TG MQTT Relay 4
This project is for the KB light stand watering. A Chinese 4 relay board is driven by a Boarduino. The boarduino gets relay on/off commands from the ESP8266 serial line. The ESP8266 is used as a WiFi and MQTT co-processor. The ESP8266 attaches to the WiFi and decodes MQTT commands. A single character is output on the serial line to the Boarduino. The characters chosen and their function is as follows:
| Command | Character |
| Rly 1 on | '0' |
| Rly 2 on | '1' |
