## Features
1. Supported sensors:
1. DS18B20
2. DHT11/22
2. Support sensor power management.
3. Automatically adds sensor configuration to Home Assistan via MQTT discovery as a sensor.
4. Update firmware from HTTPS server via ESP-NOW.
5. Direct or mesh work mode.
6. Support of external or battery powering.
1. Supported 1-wire sensors:
1. [DS18B20](https://github.com/aZholtikov/zh_ds18b20)
2. [DHT11/DHT22/AM2302/AM2320](https://github.com/aZholtikov/zh_dht)
2. Supported I2C sensors:

MQTT configuration message should filled according to the template "X1,X2,X3,X4,X5,X6". Where:
1. X1 - Sensor type. 1 for DS18B20, 2 for DHT11, 3 for DHT22.
1. X1 - Sensor type. 1 for DS18B20, 2 for AHT, 8 for DHT, 9 for BH1750.
2. X2 - Sensor GPIO number 1 (main pin for 1-wire sensors, SDA pin for I2C sensors). 0 - 48 (according to the module used), 255 if not used.
3. X3 - Sensor GPIO number 2 (SCL pin for I2C sensors). 0 - 48 (according to the module used), 255 if not used.
4. X4 - Power GPIO number (if using sensor power control). 0 - 48 (according to the module used), 255 if not used.

1. A gateway is required. For details see [zh_gateway](https://github.com/aZholtikov/zh_gateway).
2. Use the "make ota" command instead of "make" to prepare 2 bin files for OTA update (for ESP8266).
3. For ESP8266 battery powering mode GPIO16 must be connected to RST.
4. A battery powering mode sensor power management is highly recommended for greater stability.
5. Updates and setting changes are only available in external power mode. To temporarily disable battery mode, enable "menuconfig -> ZH ESP-NOW Sensor Configuration -> Enable power mode selection at startup" and set the "Power selection GPIO number". Connecting this GPIO to GND during startup will temporarily disable the battery mode.
