KingRichard (Richard T) August 2, 2021, 3:11am 5. mascatul (Sadi) July 11, 2020, 1 The generic version of my question is how can I use the Home Assistant area as a variable within an ESPHome config, such that if I change the ESPHome device area within HA the functionality changes? I want to use the area of the esphome device in a service call to home assistant. Hi, I have been using this guide to help keep a device awake for updates: I seem to have a problem that the device doesn’t reliably get the value from HASS (it does sometimes) and am really struggling to troubleshoot. Here is the script in ESPHome: - id: toggle_play then: - switch. This can be used as name for the device, but it can also be used as pre-fix for the ESPHome entities. So let’s say the water heater goes up to 60⁰C, and it’s a hot day so I set the target temperature to How can i restore a value from home assistant after a reboot or reprogramming. So after each wake-up (via GPIO), the The goal I would like to use ESPHome to create a multi-sensor for each room, with temperature, brightness, movement, air quality, etc. I can’t for the life of me figure out how to do this. 3 v to 200 Ohm resistor. I want something that acts like a boolean, but I’m not sure of what to use for scope and access. Is there a way to do this? Ideally a way that I can use to send the setpoint from Nodered. I tried using lambda’s but it won’t pass compilation. Unfortunately, I was not even able to work with variables within ESPHome. I’m using the Sprinkler Controller and it’s working great. This integration enables you to Currently, only the ESPHome tool, Home Assistant and ioBroker use this native API. This code works good with esp. From what I understand this would require using either a global variable or reading the value from HA and neither is allowed for a calibrate linear filter. This means that I will add an ESP8266 to this doorbell which will only activate the doorbell when my little son is not asleep. I would create the input number component in home assistant, then would apply the value of it to the sensro. I have use the code from gdoerr The code has been successfully read with my rfid reader and printed in the ESPhome logger Now By default a ESPHome sensor will lose it’s value after a power down and start again at 0. It’s The only way you can currently edit and save an arbitrary string on ESPHome is to link a Home Assistant text sensor to an input_text: helper in HA, and edit the text on HA. That is the issue. On my meter that happens to be 8, but when sharing Hi, I am trying to take a reading from a temp sensor and display it on an oled, I can read the sensor and display simple text on the display but when I try and display the variable I get errors, I’m new to this and I’m sure I’m missing somethinf simple.

It’s connected to a nodemcu and it’s working and I can print simple text to it no problems. Reading the docu on esphome. I would like to make esphome sensor independent on Home Assistant in that it reads weather forecast from openweathermap and controls some switches (roolls up exterior blinds if wind is coming). I’m really beating my head over how to do this. it does needs to live on the ESP and use STNP. It has an analog pressure Sensor fed through am ads1115 ADC, and a pulse flow meter fed through the pulse counter component. So I’d suggest creating a small automation / lambda that on a regular basis writes the home assistant value to a global I'd like to publish a boolean variable that I've calculated in a lambda to Home Assistant so I can use it as a condition in an automation. 0 - Hi!! I wish to have a sensor publish High resolution data when within a certain value set, and revert to a more manageable update rate the rest of the time. on_value: then: - sensor. I bought the IR modules off of aliexpress, and have the hooked up and they appear to be working correctly. Homeassistant has an id called “esptime” . Now i got that to work and i wanted to Hey, I really wants to know how I can show the value of a global variable as a sensor entity in Home Assistant.

I check the “timestamp” on the first edge and subtract it from the “timestamp” on the next one. The easiest way is to expose a service from the ESP that you can call in Home Assistant: ESPHome Native API Component. log: Create a global variable; Turn on restore from flash in the ESP8266 config; When you get a valid value for your set point from HA, store it in that global variable; On restart - until the value from the HA sensor is updated, Hello, I’m creating a load cell based scale and would like to calibrate the scale to a known weight via the internal web server or from HA without having to upload new code each time. h globals: id: threshold1 type: float restore_value: yes initial_value: “0. I am making this clock for a friend that does not have home assistant, Hi, I’m trying to use a stepper motor to create a twinkling effect on some fiber optic star ceiling. The preprocessor uses it to convert it to C++ format sht_dewpoint->update(). In “Entities”, the script does not appear, nor when trying to build an automation. I ran it like that, and it seems like esphome treats total_agua like a variable? I have no clue why however. send: data: [ 0x31, 0x00, 0xfa,0x09,0x28,0x00,0x00 ] can_id: 0x680 - Ok, not really permanent, but are global variables stored in a way in the device itself so that they aren’t lost in a reboot/power cycle? I just tried to set up a resistance sensor with ESPHome and I only get background noise with it. Hello guys, I know the way to set global variables. If Hi Homeassistanters and esphomers, anyone knows if is possibile to set a variable value for a delay within a script? I have a script like the one below, but I would like to have the delay duration coming from a global. matrix1_scrolling_text That holds the text to be shown on the matrix sign Context: I’m building a HA wireless yoghurt maker as a project. I see nothing VERBOSE logging and I can’t recreate the failure scenario either.

In ESPHOME I would create the homeassistant component which would read the value of the sensor. But there’s a catch This is a battery-operated device so I need to be in Deep Sleep mode for as long as possible. type (Required, string): The C++ type of the global variable, for example bool (for true / false), int (for integers), float (for decimal numbers), int[50] for an array of 50 integers, etc. I have tried with dalay: !lambda "id(duration) + 'min'; " but it is making my device to randomly reboot script - id: execBoostMode mode: restart then: - In the ESPHome yaml file you can indeed define a friendly_name. turn_on(). I have this done using Home Assistant template. It looks like I have to set up a substitution, like this: substitutions: VentFanDelay: 120 #delay in seconds And then, later, I use it by typing: ${VentFanDelay} Is Is it possible to send a text to a nextion display connected to a D1 mini with esphome on it? Did you solve this? Home Assistant Community Esphome & nextion tft lcd. sleeptime id: sleeptime to check the value Hello, is it possible in esphome to store a list of strings and then recall them from a lamdba? I have an esp with a buzzer and I would like some music to be played depending on a condition example: globals: - id: Hello! I recently updated Home Assistant to 2021. The challenge is that the voltage fluctuates by 0. I have two temperature sensors on a NodeMCU ESP8266. I thought with setup like this: globals: - id: pref_pos type: int restore_value: yes initial_value: '55' - id: timer_active type: bool restore_value: yes initial_value: 'true' I could have an initial values 55/true after flashing and Hi i am stucked importing forecast states in esphome. I am powering the D1 Nott that relative pressure is (still) wrong on Esp’shome page for BME280. The entity id referred to in the sensor definition must already exist in # ESPHome program to test how to control WS8212 LED strip # WS8212 LED Strip can be divided in segment, each one can be address to Turn On/Off as well as control Brightness and Flash_length # Credit and many So what I think you are trying to do is loop through a bunch of sensors named “cell_voltage_1” through 16? Your problem will be that ESPHome converts the id references to internal pointers at compile time - I don’t believe it does it at run-time like your code assumes. BME280’s absolute pressure output has already temperature taken into account, so having it in relative pressure formula again is wrong. If I follow the usual instructions, the sensors are called the same (“temperature”) in all rooms, but they should be called livingroom_temperature in the livingroom device, kitchen_temperature in the kitchen device, This is tied in with using a delay. I have set up a climate entity in HA where I can set the desired temp for the maker to hold at and a timer. Hello Mattias, as I am still at the beginning with ESPHOME and practising, I have tried to proceed in small steps! Task: when the temperature goes above 26°C, a “time” should start → the time is stored in the variable “my_globel_int” and can be changed if necessary via “HomeAssistant”. You can also define a “id” for sensors in the ESPHome yaml file, which can be used internally in the ESPHome code. 61 represents a voltage reading. It looks like variables are not accepted in entity_id. 1. Specifically, I’ve got a “one wire” (dallas) temperature sensor, which I’d like to be able to use the temperature value from in my component. To get an accurate reading I have to define the reference voltage as a configuration variable. I’ve tried to do my homework, and the closest I could find was probably this guide: ESPHome variables from Home Assistant - Schinckel. perform(); The rgb values are assigned in global variables in the code, hence when above line of code executes the I’m trying to send a list of upcoming events from a service call in Home Assistant to an esp32 running esphome. Hi all! I got stucked with my first custom integration. I have not found anything like this. Is there a way to define global varriables inside a lambda? And, is there a way to write/read data directly to the flash? I ask these questions because I am planning to program a light control for my aquarium. If anyone has any suggestions it would really help. So I’ve set up the pulse_meter sensor to read out my gas meter and I’m trying to figure out how I can persist the total number of pulses between reboots / updates, since the total value returned by the sensor resets to 0 when I update the esp. My goal is splitting various states from forecast ex “Day 1 condition” “Day 1 max temperature” etc In case it helps somebody else in a similar boat, here’s what I did to get the SlimmeLezer talking to Home Assistant. Automation can do it if it is the same volume every time, but I want to be able to change the volume. I obtain the value from home assistant as follows: sensor: - platform: ESPHome variables from Home Assistant - Schinckel. I am trying to control a thermostat knob with esphome stepper motor. Internal components will not be exposed to the frontend (like Home Assistant). I want to integrate a rfid reader. 94165 litros/min with 2 decimals of accuracy, so over the course of a week that would sum up quite rapidly. I am trying to display the set temp and the ESPHome Home Assistant Sensor. template. I would like to have some reusable functions that I can call in lambda’s. Instructions for setting up the native ESPHome API for communication with Home Assistant. 8 Ohm output. yaml: voice_assistant: microphone: mic_i2s on_tts_end: - What im trying to do is set the above and below values to a home assistant sensor that can adjust the humidity level with an input_slider` Ive built the slider on my home assistant and have the values showing on the esphome web server interface, Just stuck with getting this value into esphome. Connected a lcd_pcf8574 display to it. is_on: p5 then: - logger. I am using a potentiometer with adc on the esp, I get the value in HA as a sensor, this works fine. You can feed home assistant sensors into esphome with the respecting platforms available, for example: ESPHome Home Assistant Sensor. But I find it very uncomfortable when you need many varriables. 125, then multiply with I think that is due to something being wrong with the meter itself. I have a helper called P5 defined in home assistant. thanks for your reply. ADMIN MOD Publishing a Global Variable to Home Assistant . A helper, in this case called input_text. Is there a way to fix this? It is used for ESP deep sleep. set_brightness(id(off_brightness)). 2 esphome changelog, ESPHome now supports setting a friendly_name which is sent to Home Assistant. Hello, I’m using ADS115’s to measure the resistance of PIR motion sensors. I’d like to compare the two values so when they match, the motor is turned off. I have a global prevent deep sleep toggle and device specific ones. I've searched around but can't find anything on this and You can’t pass a string to id. g 70% brightness is displayed as 0. You can use this variable in lamda however you like. Convert the integer to text. This name will be used for the config entry, the device name, and will be automatically prefixed to all of the entities where needed by Home Assistant. So, if you want to execute a function on a component based Edit: don’t know how to run with -v option as I’m using ESPHome in Home Assistant. I have the following sensor that gets the volume level from my sonos: - platform: homeassistant id: media_volume entity_id: media_player. Can someone explain to me how can I do something as simple as assigning a value to a variable? I have this: globals: - id: zmiana_predkosci_mozliwa type: bool restore_value: no initial_value: 'false' and then this: sensor: - platform: pulse_counter pin: D4 name: "Pulse Counter" Hello, as mentioned in the 2023. I was thinking about global variables, but I can not understand how to implement it using HA. Replaced it with a 3. Then, after I turn the switch off, and the delay has ended, I want the boolean to change to false. test value_template: '10' The I got the id from home assistant and defined a sensor in esphome in this way: api: # MQTT mqtt: broker: 192. I found it by accident, but I cannot find it documented anywhere, and I wonder what other homeassistant ids are available. My aim is to have an esphome. Thanks! Hi, I’d like to measure the time (in seconds) between two rising edges on one of the GPIOs. One clear example is my water pump for the home. I’d like to be able to set a variable / number on the web_server webpage, have it persist during reboots, and use that number in some calculations. This is my first Integrating ESPHome with Home Assistant allows you to have seamless control and interaction between your ESPHome devices and other smart devices connected to Home Assistant. So this is in the pulse sensor declaration. DrewW: does not appear to add the needed input. Here, we can have a global variable sun_is_down that defaults to being true, and is only set to false when the sun comes up. First problem is the right way to define the string (char[] or String?), second problem is to store a value from a textsensor-state into my global. Below is what im looking to do Configuration variables:¶ entity_id (Required, string): The Home Assistant entity ID of the number to synchronize with. You can calculate the linear equation y = mx + c from the following:. You would use a lambda to write the value to the Hello. 5°C heat_output: gasklep control_parameters: kp: !lambda: Home Assistant Community String as global variable. Click the “configure” button next to it. Automation ESPHome is a framework for working with ESP devices, and making them easier to setup and use in a home automation environment. Components do not have a string name representation. Everything works fine but I can’t save the steps value on flash memory of esp32 (in order to survive power loss). Also keep in mind it does not have any filters applied yet (see the documentation: Pulse Meter Sensor — ESPHome) Hi all, I would like to use ESPHome to generate sensors in HA from UART reading. Can anyone help me out? climate: - platform: pid id: PID_Kachelthermostaat name: "PID Kachelthermostaat" sensor: living_temperatuur default_target_temperature: 21. ESPHome. 3 KOhm resistor and the value is the same. I’ve tried the obvious places, but I get the impression that the ESPHome documentation is a work in progress. log: thelist - globals. write: [0x49,0x4E,0x49,0x54,0x04,0x00,0x00,0x00,0x00,0x00,0x00,0x00] Hello, I’ve just followed this tutorial for displaying time and temperature on an OLED display. For some basic data I already know the correct commands to receive a nice answer and hardcode the CAN-bus command in the ESPhome device like this: - canbus. My setup consists of: Lolin D1 Mini Pro ST Microelectronics VL53L1X Time of Flight sensor The sensor is connected via I2C. HFsi March 7, 2022, 12:30am 41. 12 I believe) it does not a show a graph anymore, but “Statistics not found”. I’m I have setup a ESPhome node for which changes the brightness of the Aquarium lights via esphome automation. execute: consider_deep_sleep # prevent deep sleep I want to calibrate it using home assistant. So I’d suggest creating a small automation / lambda that on a regular basis writes the home assistant value to a global variable - then when HA is down you can use this global variable. If I move the printf outside of the if statement so it always gets displayed, I get a NaN. Hi guys, Pretty new to ESPHome and need some help from the gurus out there 😊 I’ve a D1 mini on ESPHome used for my frontdoor bell. peted (peter) June 29, 2022, 3:46pm 3. With press of template button 2 I want to stop but only if I am in position 2. - platform: integration name: "Battery SOC" id: battery_soc sensor: wattage_calculated integration_method: "left" time_unit: h restore: true device_class: energy filters: - clamp: max_value: 640 During operation, I would set the thermostat dial to maximum and let ESPHome and/or Home Assistant switch on and off the heating element if the target temperature is below the maximum temperature possibly achieved by the water heater. I can read forecast It seems like Number Component creates an entity in Home Assistant that I can show and change both in the Home Assistant GUI and in my ESPHome code/yaml. then take note that you should remove any friendly name (substitition) that Hi all, Are there any examples or explanations available (or would someone be willing to explain) how to create a custom component that uses an existing sensor model. I want to use the value/state of this helper in ESPHome in a while section of a binary sensor: - while: condition: - binary_sensor. I don’t think the ESP type is an issue. I followed the example from the stepper documentation, and the stepper motor works fine with the “stepper. set: id: Hi, I’m in the process of learning ESPhome and doing my first project. Here is the fragment of my esphome. set_transition_length(10). In order to get the value in cm I have to divide the voltage with 4. Here I have red wire on 3. My config so far: esphome: name: So I’ve been adding the “friendly_name” option into my configurations so I can try to pass a better name over to Home Assistant but it’s behaving in a very strange manner and I can’t seem to get things to act the While I can personally use a deep_sleep mode myself, I’m currently breaking my head over the following process: Receiving a MQTT value Store the MQTT value in a global int <---- Recall the int, and apply to the deep_sleep_duration I think I’m doing something wrong storing the MQTT value in the global int. disabled_by_default (Optional, boolean): If true, then this entity should not be added to any Hi, I want to use a variable in entity_id to be able to reuse the yaml file for multiple device via package includes. But it requires a either a float or a string where I’d like to use an integer. set Action. 0. scorbot_quinled_write data: command: "{{states. Offcourse, this would be very easy to do in HomeAssistant by first sending the Hello. All other options from Number. 0 and ESPHome to 2021. It looks like it’s not possible to access the array directly in ESPHome, but that you access the array in the HA configuration and in that file you export variables that ESPHome can read, then you read those variables in ESPHome. Sensor Filters. net Difference being, I’d like it to be set in either the web page, or alternatively over I can’t find any useable information about using local variables in esphome. I am going to be using the sensor to determine the distance from the sensor to the surface of the heating oil in my oil tank. For this I need I am trying to make a dosing system. It is a very good example, and it is a project I would like to implement. In another room there should also be an ESP8266-01s which switches on/off the boolian value in the HA by pressing a button. I measure the volt level from the sensor and each cm equals 4. input_text. I tried the following code but it doesn’t accept it :frowning: I tried different syntaxes but no luck so Hi! I am looking to run multiple esphome boards running the same firmware, and it would be nice if they could differentiate themselves automatically. 12. set_rgb(id(off_red), id(off_green), id(off_blue)). Considering my inexperience with this platform and that I’ve forgotten everything I knew about C++ (other than that it uses a lot of pointers), it’s taking me Basically the advice in the ESPHome documents on using the Home Assistant secrets file don’t seem to work. restore_value (Optional, boolean): Whether to try to restore the state on boot up. At one point (in the 2nd post on the thread), @ckxsmart states there is no string representation of components, so what I want to do may be impossible. This is the esphome yaml that produce the sensor if Hi all, Still very new to ESPHome and finding it a very steep learning curve. My config so far: esphome: … You may also look at this Hardware from kincony - KC8568-A4 (ESP32 Board with 2x 0-10V Outputs And I see that it would appear that with your device only one signal would be needed for variable-speed one-direction. That works fine, but I have a problem with status of device after reflash firmware, reboot or repower. boot the value is saved in the ESP32. geschirrspuler_status internal: true I can’t seem to figure out how to initiate and use array variables in esphomeyaml. It is so easy to use a sensor with platform DHT for example to show temperature in HA why no having a platform for global variables I want to show some internal values I do calculation with in Home Assistant. I’m unclear on how that would be done though. I have read posts that mention how to save to flash with global variables but whatever I tried didn’t work. We should be able to define a global string, integer, float, list, dict. Third party integrations. I want to have the hysteresis as variable that I can easily access within my code. There is an “arduino nano”, it sends data from different sensors via uart to esp-01s 433-esp01-uart. With the homeassistant time platform, the native API connection to Home Assistant will be I’m wondering if it’s possible to insert data from the MQTT payload into the ‘then’ action for on_message. Any help would be appreciated, please and thanks. Sent From Home Assistant to ESPHome: sensor: - platform: homeassistant name: "feed molly" entity_id: sensor.

I'd like to publish a boolean variable that I've calculated in a lambda to Home Assistant so I can use While I’ve programmed in a number of different languages, from low level like Assembler, to higher level like Python or Java, I’m having serious difficulty understanding how to use variables in YAML files on ESPHome. globals: - id: rfcodebinary type: char[65] restore_value: no - id: rfprotocolstring type: char[4] restore_value: no switch: - platform: template name: Send Custom RF id: customrfsend Configuration variables; See Also; Join the community; Follow us on Twitter; Source Code; The preferred way to get time in ESPHome is using Home Assistant. When I turn a switch on, I want the boolean to be true. I’d like to use local INT variable to store current dimm position (as value 1, 2 or 3): i intend to dimm only to 3 predefined values with a button (1%, 25% and 100%). attribute (Optional, string): The name of the state attribute to import from the specified entity. internal (Optional, boolean): Mark this component as internal. . The climate entity is ‘climate. 0 Hi, I am building an EPaper-Display with ESP32 board. feed_volume_molly Variable in ESPHome: globals: - id: num_clicks I’m playing with SHT31 sensor, and since it has heater i’m looking the way to temporarily enable it. turn_on: water_sensor_power - delay: 5s - script. h. I thought that this might be an authentication issue, however the time section is also fetched from the HA instance and that Hi guys, I have an esp-home device with a CAN-bus controller connected. Open the ESPHome integration page on your Home Assistant instance: Then: Find your device in the device list. I’ve read through this quite a bit and tried a bunch of schtuff: I’m looking for a very simple code sample – no interactivity, just variables, really – of how one would take a state (let’s say, “outside temperature”) in Home Assistant and send it through to an ESPhome variable where it could then be printf’d to a display. My config. 0)/(ph7_value - ph4_value) c = 7. I would like to set a fixed speed for the stepper motor, but the “stepper. Goal: read and parse hex data from a uart. net. However, I wish I can just get ESPHOME to output it without having to mess with Home Assistant Templating. [12:40:49][W][nextion:395]: Nextion reported variable name Hi I’m running the esp 32 (esphome) talking to a VFD in combination with Homey(home automation). So, i wonder is it possible to use lambda or variable (or anything except true or false) in sensor configuration variables? I mean - for my case i’d like to enable heater for, say, 5 or 10 minutes when i power-up esp module, then heater would be disabled the whole Hello! I would like to build a sort of wifi remote control with an Esp32 (and espHome). However the sensor values from HA don’t show up at all. Here is the code esphome: name: humdisp friendly_name: Humdisp esp8266: board: esp01_1m # Enable logging logger: I don’t know if you still need this, but the voice assistant component has the automation, just as pcwii showed, on_tts_start.
