Heb nu een 4 relais module een DS18B20 temperatuur sensor en een DHT11 sensor aan de Nodemcu ESP8266 gemaakt.
3 van de 4 relais werken met een dimmer van 0 tot 1
relais 4 is aan uit
DS18B20 temperatuur sensor heb ik als dB waarde ingevoerd omdat 2 temperatuur sensoren niet wil in homey.?
en de DHT11 sensor maar die heb ik nog niet aangesloten.

Werkt perfect alleen jammer van de temperatuur in dB maar dat gaat om de waarde.
