Double check your wiring maybe you have a bad ground somewhere.Easy enough! Works perfectly on my HS105 btw, so you can maybe call those HS103/HS105.
Next issue. ugh. sorry about all this. I can't seem to get my GPIO equipment outlets working.. same wiring setup I used before with my other Pi3 that was just working. so I was just moving it over to a replacement Pi3. so I know for a fact that it's something in the OS settings. Temp sensors are working fine, just not the equipment outlets.
I updated all the settings as per this page.. anything else I might be missing or should check? **Edit - Also verified I can't get an LED light to turn on with GPIO. maybe something wrong with this new pi3?
