Arduino/ESP-IDF library for providing sensors and actuators to Home Assistant using MQTT.

Home Assistant has a well defined way of defining sensors and actuators using MQTT. This library register a device with one or mulitple sensors and provide a way to publish new values for them, as well as listen for commands from Home Assistant.

### Currently supported sensors
- Atmospheric Preassure (hPa)
- Brightness (%)
- Door (open/closed)
- Humidity (%)
- Json (raw "json"-sensor)
- Lock (locked/unlocked)
- Motion (detected/not detected)
- Number
- Sound (detected/not detected)
- String (raw "String"-sensor)
- Temperature (°C/°F)
- Voltage (mV/V)
- Weight (g/kg)

### Currently supported actuators (and sensors)
- Curtain (open/opening, close/closing, position)
- Event
- Light (brightness, rgb, effect)
- Select
- Switch (on/off)


### Installation
#### Platform I/O:
Add the following to `libs_deps`:
```
   Johboh/HomeAssistantEntities
```
#### ESP-IDF:
In your existing `idf_component.yml` or in a new `idf_component.yml` next to your main component:
```
dependencies:
  johboh/HomeAssistantEntities
```

### Examples
See Examples for [sensors](examples/Sensors/Sensors.ino) as well as [actuators](examples/Actuators/Actuators.ino).

### Functionallity verified on the following platforms and frameworks
- ESP32 (tested with platform I/O [espressif32@6.4.0](https://github.com/platformio/platform-espressif32) / [arduino-esp32@2.0.11](https://github.com/espressif/arduino-esp32) / [ESP-IDF@5.1.1](https://github.com/espressif/esp-idf) on ESP32-S2 and ESP32-C3)
- ESP8266 (tested with platform I/O [espressif8266@4.2.1](https://github.com/platformio/platform-espressif8266) / [ardunio-core@3.1.2](https://github.com/esp8266/Arduino))

Newer version most probably work too, but they have not been verified.

### Dependencies
- https://github.com/Johboh/MQTTRemote @^2.0.2
  - _Note_: If you don't want to depend on [MQTTRemote](https://github.com/Johboh/MQTTRemote), you can copy the [IMQTTRemote](https://github.com/Johboh/MQTTRemote/blob/main/src/IMQTTRemote.h) interface from the MQTTRemote repo and implement/adapt/forward to your own MQTT implementation. This library only depend on the [IMQTTRemote](https://github.com/Johboh/MQTTRemote/blob/main/src/IMQTTRemote.h) interface.
- https://github.com/bblanchon/ArduinoJson @^6.20.0
- Needs C++17 for `std::optional`.
  - For platform I/O in `platformio.ini`:
    ```C++
    build_unflags=-std=gnu++11 # "Disable" C++11
    build_flags=-std=gnu++17 # "Enable" C++17
    ```
