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

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?

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 purchased 2 of these units probably 6+ months ago now, and they are really good units. kzfaq.infoUgkxcr5WULFU6yC9UUKc_cdNJT9jGa6VxO1l They are great for 3d printer plastic dry boxes, freezers, vehicles, gun safes, and more. The unit in the picture was pulled from my deep freezer and moved into my truck center console (monitoring humidity for water leak). It took a few hours to thaw and normalize temp and humidity reading going from those extremes, as expected, but it handled it well and is still running great.

Thank you

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.

won't let me past the setup prompt

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

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?

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

This video helped me. Thank you!!!

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

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

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...

Thanks my guyyy

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

Hi , How long did the batteries last ?

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

Mine won’t even turn on

2:29 The Google Nest thermostat says Low battery

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!!

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 :(

Dude it looks like your in a no freezing state but what you offering won’t work for a 20 below ⬇️ temp home I leave to work and my family is completely out of heat because the batteries go dead within days 🤨🧐 go ahead drink your coffee next time put a don’t give vídeo Bra

Soon or late your battery will die, this is a temp fix FYI

... you HAVE a C wire, just connect it at the furnace.

lolz

Are you aware of the fact that you can rotate your phone 90 degrees so your video occupies the whole screen instead of just a NARROW VERTICLE PORTION OF THE SCREEN? It never ceases to amaze me how many people are unaware of this fact and or just to dumb to rotate the phone. Please do this over and rotate your phone so the lone way is right to left. You would be surprised to find out how nice it is to see a wide screen video.

Pointless video, did u just make this video to show off your house
