No reading on DS18B20 on WiFi MQTT relay

(MATT) #1

Hi all
I’m just setting up this relay but I’m not seeing a reading for the temperature. On the Thermostat control page it just reads NaN.

Otherwise the relay seems to be working fine, WiFi etc. I can manually switch the relay on and off etc.

I haven’t changed any of the settings in the DS18B20 page but it is enabled.

What am I doing wrong?

Did you restart the board after enabling the sensor?
