1. A gateway is required. For details see [zh_gateway](http://git.zh.com.ru/alexey.zholtikov/zh_gateway).
2. Highly recommended connect an external power supply during firmware update.
3. Because this sensor is battery operated, it has an additional controller (MCU) that controls the power of the WiFi module (Module) and transmits data to it for transmission to the network. The communication is done via UART at 9600 speed. Make sure that the protocol is correct before flashing. Details [here](https://github.com/aZholtikov/ESP-NOW-Window-Door-Sensor/tree/main/doc).
