Things you will need. 1 A raspberry pi with Node Red and MQTT installed an Esp8266 a terminal block dev kit for the esp8266 some solder bread boards. some wire and sockets to solder to breadboard I use 4 wire phone line ( I also use it to extend the lines of the DS18b20’s and the Pressure sensors. it also ma…
