Wiring nest...not detecting c wire already installed

[Pat12]

Installed the c wire nest connector,  showing all wires are live, app still saying c wire not detected ?? Won't let me continue set up...help

I think you have to get the power connector to be detected not the c wire because you dont actually have a c wire connected to the Nest when you use the power connector.

24 Volt Transformer, C Wire Adapter Thermostat, Compatible with Nest, Ecobee, Honeywell Smart Thermostat, Nest Hello, Ring Doorbell Power Supply (23ft Cable)

This is what I purchased because Nest was working at Thermostat but kept going off line..did I get the wrong thing and now need the connector? Thank you for your help

Oh ok I thought you had the little power adapter.

So if you are using a wall plug in transformer you have to put one wire in R with the thermostat wire also in R so 2 wires will be together in the R, and the other wire from wall transformer in C.

Post a pic of what wires you have installed.

Watch this video he explains it.

Hi guys, everything working OK with app and thermostat, however, inside thermostat is reading about 8 degrees above the actual temp in house ..I did read it takes a few days to adjust but this morning it was correct ? I tried to post a pic but doesn't seem to be coming thru? Any suggestions or just let it ride? At this point, I'm not sure I want to keep it..I installed one at our beach( air & heating there) and it's working perfect there. At home we only have oil heat, radiators? Thanks

• Hi we finally got it to work with the app following your guide. I took a pic so u can see, a problem I'm having is now it says it's 78 in the house which is not right. I have another thermometer saying it's 73, heat set at 68...I'm worried the heat won't ever go on if its not working right? My hubs is an electrician so we know it's wired right...uggg

Here's the pic what do you think? Tia

We could not fit both wires into R so he spliced them together and put 1 wire in ?

I don't see any pics showing up in your posts. If you do a power test it should show the Vin and Lin reading to make sure you are getting enough power to R and C. If this is the Nest non learning model go to the nest and hit settings equipment power status. You should see Vin above 24v and report back what the other readings say.
