+# Arduino-ESP32 Zigbee Temperature Sensor Example
+
+This example shows how to configure the Zigbee end device and use it as a Home Automation (HA) temperature sensor.
+
+**This example is based on ESP-Zigbee-SDK example esp_zigbee_HA_sample/HA_temperature_sensor.**
+
+# Supported Targets
+
+Currently, this example supports the following targets.
+
+| Supported Targets | ESP32-C6 | ESP32-H2 |
+| ----------------- | -------- | -------- |
+
+## Temperature Sensor Functions
+
+Note:
+ * This board means the board (e.g. ESP32-H2) loaded with `Zigbee_Temperature_Sensor` example.
+ * The remote board means the board (e.g. ESP32-H2) loaded with `Zigbee_Thermostat` example.
+
+Functions:
+ * After this board first starts up, it would be configured locally to report the temperature on 1 degree change and no periodic reporting to the remote board.
+ * By clicking the switch button (BOOT) on this board, this board will immediately send a report of the current measured temperature to the remote board.
+
+## Hardware Required
+
+* One development board (ESP32-H2 or ESP32-C6) acting as Zigbee coordinator (loaded with `Zigbee_Thermostat` example)
+* A USB cable for power supply and programming
+* Choose another board (ESP32-H2 or ESP32-C6) as Zigbee end device (loaded with `Zigbee_Temperature_Sensor` example)
+
+### Configure the Project
+
+In this example, the internal temperature sensor task is reading the chip temperature.
+Set the Button Switch GPIO by changing the `GPIO_INPUT_IO_TOGGLE_SWITCH` definition. By default, it's the `GPIO_NUM_9` (BOOT button on ESP32-C6 and ESP32-H2).
+
+#### Using Arduino IDE
+
+To get more information about the Espressif boards see [Espressif Development Kits](https://www.espressif.com/en/products/devkits).
+
+* Before Compile/Verify, select the correct board: `Tools -> Board`.
+* Select the End device Zigbee mode: `Tools -> Zigbee mode: Zigbee ED (end device)`
+* Select Partition Scheme for Zigbee: `Tools -> Partition Scheme: Zigbee 4MB with spiffs`
+* Select the COM port: `Tools -> Port: xxx` where the `xxx` is the detected COM port.
+
+## Troubleshooting
+
+If the End device flashed with this example is not connecting to the coordinator, erase the flash before flashing it to the board. It is recommended to do this if you did changes to the coordinator.
+You can do the following:
+
+* In the Arduino IDE go to the Tools menu and set `Erase All Flash Before Sketch Upload` to `Enabled`
+* In the sketch uncomment function `esp_zb_nvram_erase_at_start(true);` located in `esp_zb_task` function.
+
+By default, the coordinator network is open for 180s after rebooting or flashing new firmware. After that, the network is closed for adding new devices.
+You can change it by editing `esp_zb_bdb_open_network(180);` in `esp_zb_app_signal_handler` function.
+
+***Important: Make sure you are using a good quality USB cable and that you have a reliable power source***
+
+* **LED not blinking:** Check the wiring connection and the IO selection.
+* **Programming Fail:** If the programming/flash procedure fails, try reducing the serial connection speed.
+* **COM port not detected:** Check the USB cable and the USB to Serial driver installation.
+
+If the error persists, you can ask for help at the official [ESP32 forum](https://esp32.com) or see [Contribute](#contribute).
