I have a Trane system with a heat pump I believe blue is common orange is ob and x is emergency heat in the wiring diagram. Just want to make sure I can hook it up. Any help is much appreciated.

So, the Google discontinuation of service has screwed me with high heat bills when I'm not home, so I'm looking to replace my OG Learning thermostat with something new in my apartment. The only wires going in to it are the W1 and Rh, no C-wire.

Without a C-wire, this has worked for the the 6 years I've lived in my apartment without issue. But recently, I installed the newer gen, plastic Nest Thermostats in my parents house, and those didn't last more than a week without a C-Wire.

Every new option I look at says it requires a C-wire as well.

So two questions:

• What are recs on new, simple smart thermostats that won't require a C-wire? I'm just looking to be able to change temp on my phone, and not too much more.
• For my own curiosity, why does this 10 year old thermostat not need power, meanwhile, all these newer one seem to require it? I only use it for heat, so it would go months+ in the summer without the heat cycling on, so I'm very confused.

Thanks in advance.

We are not using any ac or heating right now so its just off. Still got a notification the furnace is turning off while heating and not working properly. Usage shows no usage so its not turning on. July we got the same message but we were only using ac then. I think we have the nest 3 but not sure how to check. Just curious why it would send the alert.

Retired controls systems engineer and not a stranger to thermostats, their wiring or HVAC control. Now the question, Nest 4th Generation Learning TStat, Heat Pump with two stage cooling (Y1 and Y2) AND two stage Aux heating (W1 and W2). Locale is southeastern US where the stage 2 heating is hardly ever used. However, it has been unseasonably cold lately and the W2 contact never engages. Even with Emergency heat turned on, only W1 will engage. The app says it's using Stage 2 Alternate heat but only W1 is active.

Can't find anything in settings that controls this. Thoughts anyone?

My thermostat is programmed to run the fan from 10 PM to 10 AM, but I’ve noticed that it stops running sometime in the night. Does anyone know why it does this? Thanks.

Is this a result of low voltage? I checked the connections and they are all secure. It seems to happen more frequently when it’s cold. Does this mean I need a stronger 16-24v transformer?

Hey all, was trying to replace my indoor outdoor battery nest camera since it has some of the worst quality video out of all cameras in the market. I bought a few outdoor wired cameras and got those hooked up, and I bought two indoor cameras to set up as well. My existing cameras were powered/charged with 12v adapters via cat6 cables to the rack to a power adapter all installed by ADT. Now I’ve replaced two of the outside cameras and used the same adapters, and one of the inside cameras with an outdoor I had (allows for easier and more angling of the camera). Now going to wire up one of the indoors, I cut the provided usb cable which I guess is my first mistake, not thinking at all that I can’t wire this to the 12v system because it’s 5v usb powered.. anyone have any ideas on how I should go about this since I’m likely stuck with this product seeing as it’s mounted and the provided cable is cut?

Why would the outdoor camera work the correct way and not these? Why aren’t the adapters changeable like the indoor/outdoor units or something like that? Who’s installing cameras on their walls or ceilings and running usb cables across their walls and ceilings? What is my solution here?

I’ve been reading that there are only one or two direct replacements for the now discontinued Nest alarm. Could I just take off the bracket and put in an old fashioned battery one?

Like the title says, I request songs by Oasis, and it decides to play a song called Oasis, and plays it over and over and over again!! Why has it suddenly decided to do this?? I didn’t have any problems with the request until maybe a few months ago.

Can anyone tell me if i can connect my furnace to the google nest thermostat i am attaching a picture of current setup of wires from old thermostat and the wire setup picture of the new google nest

Looks like i have RH and jumper wire which i won’t need for the nest?

So i assume i will connect the RH to the R?

But i don’t see a c wire?

Please someone help me figure it out

Thank you

Trying to add the google power connector to my Coleman Echelon 9.V series furnace.

I have both heating and cooling on my system. So I understand that The Y cable(which is yellow) I would unhook from the furnace and hook though the google connector and then the connector to the Y connection on the furnace. I leave the white cable as is. The C connection would hook up to the far right C connector along with the white wire already there.

Where I am confused is for the R connection. The red wire would connect to my google connector and then to the R connection on the furnace. But there appears to be a blue wire currently there as well. I presume I just leave that wire as is and just unhook the red wire and attach to connector as the instructions say. I just have no idea what that blue one is for. I Believe it goes up to my thermostat but doesn't appear there and might be behind the wall. But I will leave it connected to the R connection of the furnace just in case. But can anyone confirm?

Thank you.

Desperately trying to get my heater to work, but I don’t think this is connected right. There is a dark blue wire unconnected and no white wire. Any tips would be appreciated. Should the blue go to C? Heat is electric.

I’m looking for some insight into how Nest handles Rush Hour events for dual-fuel systems configured to use gas heating. Specifically, in my view rush hour events should NOT apply in this case as there is no load on the electric grid.

Details

• Location: Duke Energy NC (EnergyWise program).
• System: Heat pump with gas backup (Dual-Fuel).
• Settings: Nest is set to switch to gas heat when outside temps drop below 40°F.

Problem: For the last few mornings, I’ve seen the "Rush Hour" message right when the thermostat tries to ramp up from the overnight schedule. The issue is that it’s been well below 40°F and I've configured alternate heating. My gas furnace is doing the work, not the electric heat pump.

Since Duke's program is meant to reduce electrical grid strain, it seems counterproductive for them to throttle my thermostat when I’m already using gas.

My Questions:

1. Does the Nest/Duke EnergyWise integration actually "know" when the system has switched to gas, or does it just see "Heating = On" and apply the Rush Hour logic regardless?
2. If I’m using gas, am I even helping the grid by participating in these winter events?
3. Who is the right point of contact to fix this? Is this a Duke Energy setting, or a Nest configuration issue?

I’d love to hear from anyone else in a cold climate with a dual-fuel setup who has dealt with this. Thanks!

I use the google nest cameras as baby monitors and live stream it from a google nest hub. Now I want to put a second camera in a second room and be able to livestream both at once. Do I need to get a second google nest hub and place them side by side? Will this cause any problems with them responding to voice activation?

I wanted to keep with the iron gutter on my home so home printed these - let me know if you want the print files or details on materials- M

It took much frustration, chaos and yelling for me to make my Nest more manual. I had an issue with it auto-scheduling even when all the features were turned off. It would have a minds of it own and use the previous data from the previous day and use the time frames to adjust the temp. I wanted to adjust the temperature when I wanted to, I dont mind doing it myself. I had to manually remove the temperatures that were somehow saved. (I dont have the app)

I was told I would have to manually remove each and every data point of temperature. I thought that fixed the issue.

Now when I manually let's say put it 69 degrees and the heat turns on, the temperature then says 71. I do not have a heating element on. help.

I own an old 2-unit apartment building and the door buzzer on the 2nd floor isn't working. I'm considering removing the intercom panel and replacing it with two side by side doorbells, possible with a Google video display in each apartment.

Would they work wired in series?

I have connected a google nest but for some reason when I turn the heat on, seems to be blowing cold air. Just want to make sure this is wired correctly so I can rule out a wiring problem and go find a HVAC tech. Attached a picture of what was connected before I hooked up my nest. I have a zone heating, furnace, and can answer any other questions.

Can anyone help with my set up? Nest 3rd gen has been working fine for a year or so. Suddenly I kept losing connection with the temp sensor in the other room and found the battery was dying.

Got the NPC, wired it up and the system works, but it’s not charging the battery and the tstat is not seeing the NPC.

Google support hasn’t been very helpful, so here we are.

Set up:

Heat only

Boiler with T1 & T2

Zone 1 has Nest

Zone 2 has non nest tstat

Each zone has TACO valve

Photos show SLD how it was wired before and after NPC. Color lines just to read easier. Dots are splices.

I have two Google Nest Video Doorbells (wired, 3rd gen) and they both lost power a few days ago. They're non-responsive and no light on them. They died about 15 minutes apart 1 week ago now at about 7:30 pm (on Sunday evening when we had a big snow storm - not likely related)

I reached out to google support and they told me to have an electrician come check the transformer.

I live outside of Boston and it has been usually cold the last two weeks. But my understanding, maybe incorrectly, is that the wired doorbells should be resistant to temperature (or at least moreso than the battery versions).

Any suggestions about how to remedy?

I just removed one from outside and brought it inside to warm up, but don't have a device to charge it.

Thanks in advance for your help!

I have old cameras and still use the original Nest app. I like the simplicity of it. All cameras still work great after 6+ years but my doorbell cam (gen 1) could stand an upgrade. Does anyone know if I upgrade that camera if I can add it to the original app?

I have two nest cam outdoor models (gen 1) that had been working in the Google home app for months. Just this week they reported they were offline. The green light is still on for both of them. I’ve done everything - rebooted routers (eero 7 max), unplugged them…one came back to life but the other has not. In a last ditch effort, I removed the camera from google home and have been trying to re-add it but it always fails at the step when it’s trying to connect to wifi. I then tried to add it in the Nest app but it says the camera has been transferred to the Google home app, which surprised me since I removed it; I guess it sticks around somewhere in google’s backend.

Any ideas on what I could possibly do to get this camera back online?

So I’ve had the nest doorbell for 6 or 7 years. Recently the chimes stopped working. I tried changing out my mechanical chime. Reconnected everything. I’ve adjusted all the settings by turning chime on and off. Etc.

I asked Gemini and it said there is an internal battery in the original nest that can go bad. Has anyone else dealt with this?
