6. Highly recommended connect an external power supply during setup/upgrade. 6. Highly recommended connect an external power supply during setup/upgrade.
7. 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). 7.

2. Model D06 Type 2. Built on Tuya WiFi module CBU (BK7231N chip). Replacement required. No physical equivalent (as of this writing). Performed replacement with ESP-M2 (ESP8285 chip) because it was in stock. It can be replaced with any ESP8266 compatible. Total response time about 0.5 sec.
