The installation of DS18B20 temperature sensors is a bit hit and miss. I have managed to enter just DS18B20 into the Enter Slave box and click save and after some time / re-boot / reset display it just starts working.
At present I have one half installed ? DS18B20 giving a live plot of a -ve 7 digit number… I can not un install it using Remove Sensor’ as the button is pale / not an active option at the moment. Have tried to reset the display to clear this issue. I have tried a few re-boots. It is still sitting there if you want to ‘look into’ it. Feel free to log in.
