THANK YOUUUU IT
for anyone that is wondering how or why:

this works only if u need a thermostat for heating BUT NOT COOLING!

[Colduck]

This way does work..I have a 2 family with 2 zones which I converted into a 1zone because I did not want tenets controlling the heat..so i put a nest E in my rental..now questions can these actually function as one one of the sensors would and still call for heat because there both programmed to my temps and schedule

FIXED! Ever since I put rechargeable batteries in my thermostat (two months ago), I haven't received the "low battery" message once. I think the low voltage charge from my air handler is going to the batteries, not the thermostat itself. Before, when I first installed the thermostat, I got the low battery message a few days after placing batteries in it, and had to replace them about every week.

I have a Williams wall heater and millivolt thermostat. Running power, even a 24V transformer would be a major pain. Does anyone make a battery powered Smart WiFi thermostat that will work with a 2-wire millivolt system with no power? Is that even possible? Is this how you set your up?

[rickygibson]

won't let me past the setup prompt

don't listen to this also, finish your damn coffee before filming a video.

We tried to connect one using the Nest power converter and it didn't work. I'm surprised you were able to get it to work without a C wire. I'll have to give this a try and tell it we have a C wire. I disconnected the power converter and put my old thermostat back on so we can have heat just until we get this figured out. You say it charges your batteries? Have you had to replace them much? Wondering how long the batteries that came with it will last till i get some rechargables. Will it still control your furnace even if the batteries are dead? BTW, if anyone needs the Nest power converter, Google will send it to you for free. there's a link in the setup app. don't pay $25 for one.

I also did this and yes it works but it will not have constant display. And constantly reminds me to add a c wire

[TheRevengeSociety]

I just installed one of these and I have a c wire seated in to the connector but the hardware itself is not detecting it. I'm still in the preliminary stages of troubleshooting this though. All the other functions work just fine though.

Do you have to recharge the nest e upstairs without a c wire? I haven’t been able to set up a nest e in my house because it dies and doesn’t turn ac on just the fan only. I have yellow green red and a blue instead of c for o/b with jumpers on old thermostat

[NYEK_GTR_]

It’ll eventually give you issues. Especially if you live in the northeast or any cold region during the winter. I install nest products for a living and a c wire is needed. Otherwise you can use a learning thermostat that will usually function fine with only heat. If you have heat and ac you will need a c wire or plug in transformer. You can use a nest E thermostat but they are hard to find due to being discontinued for this new model. Not a fan of this model btw...

[rebeccanorman]

I have a nest and it’s giving me an M20 error and my AC won’t turn on. Can someone help me figure this out?

[pichanorellana]

I installed one of these and have to replace batteries every 2 days. A little annoyed by it.

[ladoucpa]

it won't let you continue after it says no power to c

[ninjamaster]

How long does it last exactly, without a c? Does the thermostat send a message to change the battery?

My concern is that this either shuts off, stays on or flicks my boiler on and off when the battery gets low,

They originally said it could be battery only, but recently said it needs C

Don't drink coffee while doing a video. It is rude.

[AtomicElectronCo]

What's the make and model of your door lock? I like it and it looks solid.

2:29 The Google Nest thermostat says Low battery

[michaelmakes]

To whom it may concern....ditch this " instructive" video...too much is wrong with it to explain...plenty of others out there...run, don't walk!!

[KatyRD]

This is so stupid, google says online that it works without a C wire and I’m trying to set it up and it’s not working :(
