ecobee Smart Thermostat Enhanced - Programmable Wifi Thermostat - Works with Siri, Alexa, Google Assistant - Energy Star Certified - Smart Home

This is not battery operated. If your house’s thermostat wiring doesn’t come with a C wire, consider paying for professional installation. The C wire is what supplies constant power to this thermostat, but some houses didn’t bother to run that wire because they assumed your thermostat will use batteries. This does NOT mean you’re out of luck, but it does make the install more complicated.You will either need to run an additional wire through your walls or you’ll need to install the included PEK (not all thermostats of ecobee include it, so check your model and house wiring before buying). The PEK is, in my opinion, an ingenious piece of technology that deserves praise for how magical it seems. It repurposes 2 existing signal wires so that one wire becomes the C wire carrying constant power, and then the other wire carries various voltage levels to indicate multiple signals between thermostat and PEK; the PEK then translates those voltages and splits them back into separate wires for the rest of the system.However, it does require work near or in your HVAC unit. I had to spend a good bit of time carefully inspecting the colored wires, making sure I knew exactly which is which. Again, houses are all different and some might use nonstandard wire colors; for example, my blue wire functioned as the Y wire, with no yellow in sight! You should be absolutely sure of what does what; you’ll probably want to read up on the purpose of each wire. ecobee includes stickers to help you label the wires as you investigate.But once the PEK is installed, the thermostat works beautifully. The touch screen is responsive, it walks you through startup easily, and the app is full of features and settings galore.Again, paying for a professional will save you wiring confusion whether you need the PEK installed or just run a new wire.

I'm bias but I love electronics like this. It is polished and just works right out of the box. The instructions (on your phone) walk you step by step through installation for whichever version of the thermostat that you buy. They even prompt you to take some pictures along the way that could be shared with support if you need to call them for any problems. I didn't have any problems so I can't speak to tech support. Out of the box you'll need to connect it to your WiFi and then you have access to most of the controls via the app.. A few things require you to be on the device to adjust, but those are one and done settings. Touch screen and trim ring look gorgeous. My favorite part, being able to set the fan to run a min number of min each hour. Keeps the house from getting stuffy when indoor and outdoor temps are close. The A/C over cool to manage humidity is also great as sometimes the A/C needs to run a little longer to pull the moisture out of the air. Would recommend.

This is a great thermostat. Great build quality. Easy to control and works great with my wifi and Android device.

Much more attractive than the white Honeywell that it replaced. The Honeywell had become erratic at reaching the cooling set point so had to be replaced. However, the Honeywell user interface is slightly more user friendly - the features most frequently used were not buried as deeply in the menu structure as the Ecobee. For example, setting the fan behavior is easier on the Honeywell.that being said, the Ecobee is working well.

After struggling to read my old thermostat, and doing plenty of research, I invested in this one. Frankly I should have done it a lot sooner. This thermostat runs my home temperatures seamlessly. Once I set up my preferences it took over and I have not had to constantly adjust the settings. I can run it from my phone, my tablet and from the thermostat itself. Easy for a senior to operate. In addition I have saved money by using the suggested settings. Highly recommend this product, easy to install, although I did not install it.

Works great, easy to install and my electric bill has gone done! I love that I can program it when I am on vacation to pre cool or heat the house depending on the season!

Very VERY disappointed! Bought 2 of these as I have 2 zones in the house. Looking forward to operating these remotely on my iPhone.Had them professionally installed. Worked well for about two months. Then the first one failed. Would not call for air conditioning at all. And it was not on the programming or wiring.Had HVAC guys come back and go over everything. $400 later they concluded it was broken. They put a Walmart $25 simple thermostat on it and works fine. Tested the ecobee on other wall locations and still won’t work. The second one was working fine for a couple more months then that one went too. NO HELP from customer service which is so automated with AI directing me to self learn online. When I have gotten a human ( took a long time ) …he was reading from a flow chart manual and seemed like a young kid with minimal experience. Nice enough but suggested having HVAC guys come back. I’m into Ecobee products for over $400 plus install and multiple service calls to the tune of over $1000. The worst is the poor customer support. No refunds as well !!!I’d like to be say it’s the internal wiring but I took them to another location and they still don’t work. Did I just get a bad batch ? That seems reasonable. But NO support. No refund. No replacement! Tired of A.I. and automated “support.”It’s the time lost and aggravations they deter me from ever recommending this product. HVAC company has 30 years experience. Strongly urged me to purchase Honeywell as they have minimal to no complaints. They often have issues with NEST and Ecobee. I took it a step further and asked sone electricians what they recommend and Honeywell was their choice. Live and learn. Do not buy this product. Do not expect support. So very very disappointed.

I have an Over 100 yr old home - furnace is over 10 years - the app stepped me through Connecting and installing thermostat. I am loving my new smart thermostat as it is up and running in less than an hour.
