Without a common wire the nest (and other smart stats) use ugly hacks to drop the voltage between R and one of the other control pins. The side effect is that a lower voltage means more current to maintain the same wattage. This can cause damage to both old school transformers and new digital control systems. The nest will also short cycle your system occasionally to charge the battery if there is no C wire and the system isnt running enough.

Their website sucks ass. I tried getting an ecobee from it and it wouldn’t let me get it, even with all the proper information.

Despite all the “DIY” references in their marketing, Nest recommends installation by a heating technician or an electrician, in part for this reason.

Having installed a Nest myself, I recommend heeding their suggestion. I replaced a troublesome Lux thermostat with a Nest. It turns out my home’s previous owners had mislabeled the wiring, which was causing the Lux to malfunction and meant the Nest didn’t work at first. It took me about an hour to figure out the issue. A professional probably would have had it figured out in no time.

That's what the other person is describing.

If you only have two wires to your thermostat, they are designed to be connected or not connected; that's the only way the system is designed to communicate. The thermostat can't power itself from two disconnected wires, and if it connects them, then it turns the heat on. Enter the Nest Power Connector that only kinda connects the wires...enough to pull a bit of power for the thermostat, but not enough to actually turn on the heat.

Opinions will vary whether that is okay or not, but it is objectively using things in a way they weren't designed, and the majority opinion of HVAC professionals seems to be that it's no bueno.

For anyone concerned about this, I would recommend getting the Sensi thermostat. It works great with 2 wire systems and can be controlled through an app on your phone. I've been using two for about 3 years now. Great purchase.

degggendorf t1_iy9sh5b wrote

For sure, it seems highly dependent on the exact system whether it likes it or not, in addition to how frequently the heat runs and how much it can charge its battery.

I ended up running new wiring for my two heat-only zones to avoid all the headache. Before that, using a 24VAC wall transformer with wire running up to the thermostat worked well too, but was kinda unsightly.

I second that. The Sensi uses a battery (I think to make up for the lack of a C wire). I have no complaints about it. The battery lasts a long time. You get a warning when it's getting low. And it has all the same features like a smart app, event alerts, schedules, and Alexa integration. It also has a setting to prevent short-cycling.

Lol have o problem with the G's, G men within reason, the privacy thing is a low issue. I don't like not being in control but whatever. My phone freezes at least once a day. I don't need that in a thermostat. I'm also heat sensitive. I can't do too cold so any temp restrictions on top heat is bad, and frankly I grew up with a wood burning stove. A set on top thermostat is ok by me. I'm not hesitant to change I just want it to actually work.

Jack__Squat t1_iy9ubq3 wrote

I've never seen an article or study that this is actually happening. I've seen plenty that say it's possible. Or that we may get some opt-in feature for a cost savings, but I've never read that it's being done by force. I've had 2 smart thermostats for almost 10 years, not once has my heat gone down without me changing it. Why would they even want to. Assuming a grand conspiracy is in place the oil barons pulling the strings would want me to burn more oil or use more juice so they can bill me.

I used the rebate and bought an ecobee with voice control since it’s compatible with HomeKit. Bought a c wire on Amazon that plugs right into the wall outlet - pretty good rebate program, I’m happy with the ecobee so far.

My pops has had his nest for 3 years or so... 0 issues and he loves it. He says it's saved him money and great for when he's traveling.

Granted he's got his home smart teched out. From solar pannels with battery backup to a smart garage door opener.

noungning t1_iy9vmzp wrote

I bought 2 when someone else posted it.

I have the nicer one but it doesn't have battery and died in the winter because it didn't get enough power from the boiler lol. I kept talking to Nest and they sent me 2 new ones to try and it kept on having the same issue. And they basically abandoned troubleshooting.

But since I saw that this model has the battery I figure I'd try it again. But I won't be installing it til sometime in the spring just in case it doesn't work and we'd freeze in the winter unless I swap it with the old thermostat again.

No no conspiracy. I'm not that type. Nuts sure not tin foil though. I'm more talking about ok I set it low when I leave. It freezes and locks up. I come home it isn't warm and I am now stuck. I don't think they would turn it down on me

He does use oil for heat but that's his next thing to tackle.

You may be able to get the Nest Power Connect for free from Google.

I got my nest from this promotion last week (came pretty quick), only to find out this version needs a common wire. I have two Nest E thermostats for other zones that work fine already so I didn't think much about it. I coughed up another $40 for the Nest Power Connect and a trim kit. I got it all hooked up and it works ok, but I still get some occasional errors about unstable power. Then today I got an email from Google offering a free power connect to help with the power issue. So maybe you can skip a step and get one free from Google.

1, The Nest has a microphone, and a CCTV that constantly monitors the home.

2, The nest can be overridden by a remote source. RIEnergy could lower your heating or cooling setpoints at any time.

Well that goes against the info page then. I might just end up reselling these in that case. I don't want to deal with the headache I dealt with the other one I have.

I have a common wire on my AC but not on my boiler, so it works fine in the summer, but not in the winter lol. I tried almost everything in 2018 and finally gave up. That old one is in a box somewhere in my closet.

Look into “How your power company can remotely control your smart thermostat” before you buy this

Yeah it’s all fun and games till the power company starts fucking with your thermostat. Check the fine print. I would be very surprised if they didn’t reserve this right

dramaticlobsters t1_iyaclqm wrote

1.The nest thermostat does not have those, the nest doorbell does.

2.Just like any other electronic device, you have to give outside sources permission to do this. The only stories you can find about this involve people agreeing to energy saving programs that they didn't actually read up on.

Not to sound like a Luddite but what are the advantages to this over the old round dial I have? I’m interested but is there a benefit or is it just cell phone connectivity

MavDrake OP t1_iyanltd wrote

The main way smart thermostats save electricity is by reducing your heating and cooling automatically when it's not needed. The device determines the need by predicting when people are home and away.

Smart thermostats like the ecobee smart thermostat can reduce energy bills by up to 23%.

My pops has a nest and he says it definitely works.

Features Control From Anywhere You can change the temperature, adjust your schedule and more from the free Google Home app.²

Eco Temperatures The Nest Thermostat can use internal sensors and your phone's location to check if you've left the house. Then it can set itself to an Eco Temperature to save energy.

HVAC Monitoring HVAC monitoring looks out for many heating and cooling system issues. If something doesn’t seem right, your thermostat can send you an alert.³ If you need to replace your air filter, you’ll get a reminder. And you can book a visit with a Nest Pro right from the alert.

Quick Schedule The Nest Thermostat comes with Quick Schedule. When you set up your new thermostat, you can easily customize your schedule. And you can always adjust it from the Google Home app.

Easy to Install Installation usually takes 30 minutes or less. Just follow the simple step-by-step instructions in the Google Home app. For most homes, there’s no C-wire required, which makes installation even easier.⁴

Easy to Use Just swipe the touch bar on the side of the Nest Thermostat to change the temperature, and tap for settings.

Voice Control Just say, “Hey Google, turn up the heat.” The Nest Thermostat works with Hey Google on your phone, Nest speakers and displays. It also works with Alexa on other smart devices.

I didn't even know this was a thing. Did you run it through the wall and punch a hole by the outlet or did you run the wire on the outside?

No my point is that several people have already posted this on this r/ thinking it was the other one so I’m making it clear it’s not what one might think. Even the RIE websiite doesn’t spell it out. But if you need the last word, go for it.

I don't live RI , But I wonder if this will be like Texas and another state I can't remember right now . You get the smart thermostat ,sign a contract that gives them the right to regulate your heat or A/C . I would be very leary of this myself .

The fact that we clone things is Dystopian as well. Google has it's fingers in too much. That's true. However I try to scale it too. Out of all the dystopian shit in this world where does Google rank. They monitor and follow you sure, track your location cookies etc, and unfortunately that's inevitable. It's going to happen. Do they censor things yes. But buying their products is a choice. Our own government and others do far worse in the name of security and safety, which includes everything that google does as it does it with their help, and many many other sick and twisted things. So. Do I like it. No. Am I bothered by it. Like I said in many other posts, minor yes, do I like the ability to not waste heat but also have it set to the temp I need it coming home. That I say is a plus. I live alone, no kids, no wife or family out here .. it helps.

Status_Silver_5114 t1_iyb36rw wrote

most people don’t realize there are more than one model of the nest and this is basically Nest Lite. Ergo folks may be buying this thinking it has features it does not have. So pointing that out because the RIE email and Link doesn’t do that. And all of this has already been covered in this r/ last week. So adding context for your post.

I've had my nest thermostats for 5+ years and never had an issue. It was a pain in the ass having to call for help to do the work around, but they've been working for years and the heat has never shut off.

I have no idea. I'm not into all that technical stuff. I remember buying them ready to wire them myself and got stuck at the C wire I just didn't have. There was a work around someone was able to figure out.
