# Thermostat Example

This example demonstrates how to configure a Home Automation thermostat on a Zigbee Coordinator. Is has been modified from the [ESP Zigbee SDK Thermostat example](https://github.com/espressif/esp-zigbee-sdk/tree/main/examples/home_automation_devices/thermostat).

## Hardware Required

* An ESP32-P4 connected to a coprocessor with 802.15.4 support (e.g., ESP32-H2 or ESP32-C6) running this example. The ESP-Hosted Transport **and** UART should be connected between the two SOCs. See the [OpenThread and Zigbee Support](https://github.com/espressif/esp-hosted-mcu/blob/main/docs/openthread_zigbee.md) documentation for more information.
* A second board running as a Zigbee end-device (see the [ESP Zigbee SDK temperature\_sensor](https://github.com/espressif/esp-zigbee-sdk/tree/main/examples/home_automation_devices/temperature_sensor) example)

## Configure the project

Before project configuration and build, make sure to set the correct chip target using `idf.py set-target TARGET` command.

## Erase the NVRAM

Before flash it to the board, it is recommended to erase NVRAM if user doesn't want to keep the previous examples or other projects stored info using `idf.py -p PORT erase-flash`

## Build and Flash

Build the project, flash it to the board, and start the monitor tool to view the serial output by running `idf.py -p PORT flash monitor`.

(To exit the serial monitor, type ``Ctrl-]``.)

## Application Functions

- When the program starts, the board, acting as a Zigbee Coordinator with the `Home Automation Thermostat` function, will form an open network within 180 seconds.

```

- If a Zigbee device with the `Home Automation Temperature Sensor` function joins the network, the board read its manufacturer code and model then add it to the binding table.

- By clicking the `BOOT` button on this board, it will read the temperature value, temperature measurement range, and temperature tolerance from the remote board. Additionally, it will configure the remote temperature sensor to report the measured temperature value every 10 seconds or whenever there is a 2-degree change.
