SmartThermostat Lite | Black

I've had this thermostat 2 1/2 months now. I bought it along with 2 remote sensors. My original thermostat was installed in a hallway, close to one of the return vents. I believe this threw off the temperature measured at the thermostat. My master bedroom was always hot in the summer and cooler in the winter. Now I keep a sensor in the bedroom and bypass the thermostat for temperature purposes. You can set it to average between the thermostat and sensors but as I said I only use the sensor for temp readings. Looking at my electric bill it has actually decreased slightly versus last year and the outside temp was about the same. Much more comfortable in my house at all times of day. I like that I can monitor and change temps from my phone while away and also like that the thermostat can enter smart "Away" mode and adjust the temp to save energy if it senses nobody is home. I have a variable-speed air handler and heat pump and was concerned this wouldn't work with it, but I checked with customer service beforehand, sent them a picture of my original thermostat wiring and they assured me it would work. Their enclosed instructions seemed to indicate I would need to do a bit of wiring work in the air handler but this was not the case, all the wires were there on my old thermostat so installation was a breeze. If you have problems contact customer service and they will walk you through it. Definitely recommend this to help with comfort in your home, without adding an additional A/C.

I got one of these for Christmas 2017, and installed it the following day. I have a smart home and mainly got it because I like to automate everything. I was surprised by how much of a difference this thing made. I just installed my second one last week on our top floor. Our house is 3 stories and nearly 6K sqft - additionally, it is propane powered heat, so it can get expensive if not managed properly.First off, the installation can be tricky because nobody wires HVAC systems in a uniform fashion. I did it wrong both times but I called support and 5 minutes later, they were both working perfectly. Send them a few pictures and they tell you how to change up your wiring. The app is great and makes it easy to set your schedules and modes. I have them both integrated via smartthings and alexa, so changing settings is super simple even from the comfort of your easy chair.I decided to get a second one after I reordered propane last month. I expected 1300 gallons, and only needed 1000, so I saved 300 gallons of propane over the same period of the previous year. Propane goes for between $2-$3/gallon, so these things will pay for themselves in months if you set them up properly around your schedule - I saved ~$750 from December 2017-September 2018. The 3 lite has everything I need. Love the subtle refined looks unlike Nest which screams "look at the smart thermostat!"Anyway, house is comfy when you walk in the door at night, vacation modes are handy and integrates with smart hubs and Alexa to complete my geek thing. I'll be ordering a 3rd when I add a zone for the basement in the spring.

I left home for an extended period in the winter, with confidence the Ecobee thermostat would reliably let me monitor and control the house temperature from the remote app. It proved me correct.

At my old house I did a ton of research and ended up buying an EcoBee 2 although I originally was thinking Nest. Compared to my friends with Nest, I think EcoBee is much more functional and matches my needs better. I just moved and right away I bought 2 of the EcoBee 3 Lite (new house is 2 stories so I needed 2).First off, install is easy and they include everything you need with easy to follow instructions. They include a power booster attachment if you don't have a C wire but for all 3 of these I've installed, I found my wire bundle had an unused wire so I just hooked up the C-wire and used that. It was really quick and easy and took maybe 10 minutes for the whole install.The thing that really pushed me towards EcoBee were the sensors. I've bought 4 room sensors and have them all over the house. Our thermostats area usually in a hallway but I care way more about the bedrooms we're sleeping in, living areas we're hanging out in, etc. Being able to average those in really improves the comfort level of the house. Using the "follow" function has been really useful allowing us to only average in occupied rooms to not over cool/heat for rooms that don't matter.The app is easy to use and I have it hooked to Google Home as well. There are tons of settings I can nerd out on, tweak for my house, etc but also you can leave it with factory settings. Also, the HomeIQ is interesting to look at and try to improve our house's performance.I've used these on a 2 stage A/C unit as well as a 2 unit house and it handled those nuances with ease and really simplified setting them up for me. I also got a rebate for installing these from both my Gas and Electricity company so I got $150 back making them cheaper than a standard thermostat. I'm also able to enroll in my electricity company's Smart Energy program which gives me credit on my bill for letting them adjust my thermostat in high use times. From that alone I've gotten over $50 credit on bills so I'm already in the black with these purchases before I even look at energy saved for being able to program them better, set vacation times, adjust the tmp from my phone while not at home, etc.Overall, I love the smart thermostat and can never go back. I'm making money on them and the house is much more comfortable and efficient. You can go crazy with settings and nerd out or do a basic install and still see huge benefits. I much prefer the EcoBee over competition such as Nest and recommend it to anyone!

I've lived with this thermostat for about 1 month now and it's better than I thought it would be based on some prior reviews. A few observations based on what I've seen.1. Contrary to at least one popular review, the temperature sensor works just fine. The thermostat's screen produces heat which the device then automatically compensates for. If you put a thermometer directly on top of the thermostat it will read a few degrees warmer than the actual air temp.2. I simulated a power outage and then a few weeks later experienced a real one. In both cases the ecobee had no issues reconnecting to my wifi (Orbi mesh 5) and all setting resumed normally.That said, I have experienced some unexpected behavior with this unit. I bought this originally because I wanted to place remote sensors in our bedrooms so it could focus on keeping those the right temp. The software is very handy here in that you can tell it which sensors to use at any time and which it should ignore. However I've discovered that if the thermostat or another sensor drops ~5 degrees below the set temperature, the system panics and will start "seeing" those sensors again and try to get them up to temp again. Not a bad idea conceptually, but very annoying that the user doesn't seem to have any control over this override.Still very pleased with this thermostat and it's a big improvement over our old one. They are pushing out regular software updates so hopefully this is something that can be fixed later.
