Smart thermostats: Nest or Ecobee3
1Since we’re building a house (which will be ready in 2 months!!!) we’ve started looking into getting a nice smart thermostat. Anyone have either the Nest or Ecobee3?
We’ll have zoned heating/cooling (so we’ll need 1 for the main floor and 1 for the basement), and it would be great if the thermostats would talk to each other.
Right now our gas company (Questar) is offering a $100 rebate for up to 2 of either brand.
Nest is $250 right now, and Ecobee3 is $200 (momentarily on sale), so my total would be $300 for 2 Nests or $200 for Ecobee3’s
Any recommendations between the 2?
p.s. Amazon and Home Depot are where the Ecobee3’s are on sale.

i’m not sure about the ecobees, but the nests can talk to each other.

@carl669 I thought I saw that somewhere before, thanks! Do you own one?
@luvche21 i do, but only one. and, we only have heating as well. i got it for free. i looked back at old bills for the winter months, prior to when i got the nest. it looks like the nest has saved me anywhere from $5-10 per month. so, free nest + $5-10/month = profit!!
I am in a rental right now but looked into buying an ecobee specifically for the remote sensors. Our thermostat is in the hall near 2nd and 3rd bedrooms, master is in the back of house. So it can get cold in second bedroom trying to keep master cool enough in summer (or thermostat cuts off when master is still warm). So i wanted to be able to sense temperature in master and control based on it at night, or on 2nd bedroom also but only when it’s occupied.
Looking at buying now so following this thread with interest. I’m still leaning ecobee so far but automation capabilities also interest me.
@djslack what automation capabilities does the ecobee not do?
@luvche21 I didn’t look into it a year or so ago, I only wanted to solve a temperature problem. I see the new version supports homekit and alexa, so im thinking there’s not much it doesn’t do.
@luvche21 Do you have pets?
@cinoclav nope
@cinoclav
@DMlivezey @luvche21 The point of my asking is there is a minor concern with ‘learning’ thermostats. For those that have pets that roam the house, if you use your thermostat’s ‘away’ setting, it may cool/heat the house to an uncomfortable temperature for your pet. Particularly if it’s not in the room where a sensor may be and the thermostat doesn’t know your pet is there.
As for me, I just bought a Lux Geo. I work days, my gf works nights so there’s typically someone home most of the time. We don’t need a thermostat to learn, I just wanted one I could control via wifi or remotely. Plus I liked the looks of it and it can run on batteries, 24v, or micro usb.

Maybe you’ve already narrowed the choice down, but I’m happy with the Emerson Sensi. It’s about $110 at Amazon. We only have heat, and the house only had 2-wire thermostat wiring, so I had to put in a 3-conductor wire for it. I’m happy enough that I’m scheming how to get new thermostat wiring to the upstairs thermostat location to put a Sensi there.
It’s cloud-based, and has apps, and it sent me email this week when the humidity was high inside. All that 21st century stuff.
@sligett I haven’t looked much into anything but the 2 mentioned above, but will look into this one, thanks!
I adore my ecobee3
!!!

I have it along with two sensors and it works like a dream.
For sleep, it only uses the temperature in my bedroom. The rest of the time it follows me around my house.
I also love using Siri to control my bee, although it works just fine from the ecobee app.
Feel free to ask me any questions about it.
@curtise well, I pulled the trigger and bought 2 ecobee3’s tonight! Looking forward to setting them up! I doubt I’ll set them up until August when our house is built. After the rebate, $100 each isn’t too bad!
Any favorite ways to use it (settings, etc) that you would recommend using right off the bat?
@luvche21 Basically, it just works out of the box… I use the home
, away
, and sleep
settings, and I also created a morningrise
setting which, like my sleep
setting, only cares about the sensor in my bedroom, but warms the temperature a few degrees after the cooler night to help me wake up naturally.
schedule based on my usual patterns - so days when I am usually out a bit later, I have it set to home
around 10pm, whereas other evenings I have it set to home
around 7:30.
, so I use Homekit to set a geofence. Now, whenever I leave the house, my ecobee
automagically is set to away mode, and when I return, it resumes my schedule. On particularly hot or cold days, I tell Siri I’m home
as I’m leaving the office so that the ecobee
has extra time to get the temperature back to where I want it, rather than wait till I get home to start heating/cooling.

I turned off the Enable/Disable based on sensor occupancy, as I found it somewhat unreliable and slow to change, and instead set the ecobee
I have a modern Apple TV and the iPhone
Oh, another thing I love is that I set it to have the fan go at least 5 minutes of every hour, whether or not the heat/cool comes on. This ensures a better distribution of heat through my house, and also keeps the air cleaner.
Go with the Nest if you like a company owned by a company that buys things (companies), gets tired of them and either neglects them or shuts them down. And incessantly collects personal data.
@RedOak Microsoft?
@thismyusername good one
- if anything, they might hang on to things too long. And they don’t spend nearly much money doing it as the other monolith.
We’ve been really happy with our color touch screen Honeywell (9500?). Got it for $160 from Newegg. That model has been around forever. We like that since it controls our HVAC system.
This might appeal to technically inclined cheapskates like myself:
I swapped our apartment’s basic thermostat with a Radio Thermostat CT30 for a couple of bucks, then upgraded it to the CT50 (also sold as Filtrete 3M-50) with a $50 WiFi module.
It has the usual cloud-based control and monitoring and mobile app, but the real selling point (aside from being half the price of anything else) was the open remote API.
It has a pretty decent touchscreen but it’s mounted behind our TV, so I made my own sensor to send it remote temperatures. Other people have gotten it to work with Alexa.
@trisk That sounds really hard! …for me at least…
With the rebate, I only spent $100 each, so it didn’t end up being too much more than yours after all, which is especially appealing since I’m not sure if I could have pulled that off without learning a lot more than I already do.
@luvche21 So did you go with the Ecobees?
@djslack Yeah, shoulda mentioned that - ended up going with the ecobees. They’ll work well with the two heating/cooling zones (which was my biggest hold up.
@djslack one thing I didn’t think of right off was being able to control temperature based on bedrooms at night, that will be nice. I’ll only have 1 sensor for each, so hopefully that will be enough for now.
@luvche21 2 packs of sensors are like $60 on amazon IIRC. You can always add them on later. I think the sensors track whether someone is in the room so they know which parts of the house matter at any time.
I know it will be a little while before you get in the new place but share your thoughts once you get them working!
@luvche21 if we hadn’t gone “traditional”/“safe” (The Honeywell 9500(?)) we would have gone with the Ecobee. Chickened out due to being burned too many times by dead newish companies and the resulting dead support.
@djslack Yes, right around that price point. I’ll write something up as long as I remember (…lots going on between now and then with a new baby and moving and all, so I might very well forget).
@RedOak That was another reason why I was hesitant too, although I’ve never been burned by newer companies. Well, if they end up going under after a few years, I’ll still be able to use them as a ‘dumb’ thermostat.
@luvche21 You did get a great net deal. At that net price we would have gone Ecobee. I have to check our local utility since I believe we might be eligible for a rebate from them.
I just got the Zen Thermostat. Came from my security system provider, but was crazy easy to setup and operate, if that’s your thing. Works with most home automation systems.

@ACraigL Looks nice, but my gas company doesn’t offer a rebate on that one
Personally I turn the thermostat up to 80 when I leave and down to 70 when I get home. I rarely pay above the minimum for electricity.
A client of mine has me administrating an ecobee thermostat and collection of Honeywell smart thermostats. The Remote Management options on the honeywells are eclipsed drastically by the plethora of options ecobee offers.
When you ask if they can talk to each other could you clarify what you mean by that?
