My internet is on but on the app its saying that the nest thermostat isnt able to connect to any wifi connection. On the device its saying the Rh wire has no power error E74. I removed the cover and checked the wire and it is quite snugg in place. There is still no resolve. Please help it's hot in here.

Hey all,

 

Sorry to hear you are having trouble with the power to your RH wire. Apologeis for the late reply as well. Please let me know if you are still having any trouble from here, as I would be happy to take a closer look.

 

Best regards,

Jake

I ended up having a HVAC guy come out.   Turns out on of my kids shut off the emergency gas switch and I didn't realize that was controlling the thermostat 🤦‍♀️. We just moved into this house and still learning 🤣
