Great functional controller that does the basic job expected from a controller. However....YOU CANNOT USE THE WIFI ABILITY UNLESS YOU REGISTER THE PRODUCT, BUT BUT BUT YOU CAN ONLY USE A USA TIMEZONE.!!! How hard is it in this day and age to include the rest of the world???

4.0 out of 5 stars Very good T'stat; the install can be a bit tricky for the amateur

I gave it 4 stars only because of a lack of clarity using an Android to set up. But let me digress.First off the product is very good; and mechanically, it's easy to install. All I needed was a screwdriver and a pointy nosed plier to put the wires in. And it's versatile for just about any HVAC system. Shipping was less than a week in TX.In my case, I have a heat pump. I spent time understanding the features of my system (emergency heat, meaning 2 stage air handler but no Common wire at themorstat since I had a manual t'stat).My installer was kind in that they had the common wire spared in the t'stat and I tested that with voltmeter to confirm voltage between Red and that wire that it read the 24 VAC and I knew it was the common.Once I had all my wires properly landed and then turned back on the breakers at the air handler, I was faced with the setup. This is where things got troublesome. I had the Sensi app already installed and a login setup. So the first step is to connect to Wifi. I tried everything I could and Googled for help and no matter what, would not connect. (Keep in mind there are a list of routers that it is NOT compatible with so make sure to check that list before you even start. Go to Sensi website for that list.)So after 20 minutes of fiddling (and I'm a past IT professional) and realizing I had an hour before their support phone line closed, I gave them a call. I was pleasantly surprised that I got through quickly to a lady who was very helpful. After running through the basics of turning Data off on my phone, and making sure I was connected to a 2.4 ghz wireless connection, and that my router was compatible, what I then learned was that there are several steps that are not clear in any instructions. First, when you are in the App and connecting Wifi, you will see the wireless connections pop up and list the available wireless networks. BUT, you have to give it a few seconds and suddenly you see a Sensi network show up. You have to select that as well. Then the t'stat temporarily disconnects the Wifi and connects to a Sensi server and downloads a firmware update and takes a few minutes to do that. Then the t'stat reboots and you are asked on your Android a second time to connect to both the Wifi network and to check the Sensi network a second time. Then you are ready to manually put in your Wifi password twice. And you finally are past that step.Next you go into the Advanced Settings on the touchscreen of the t'stat and to the HVAC setup icon. There you need to know your type of system; heat pump, 2 stage air handler/1 stage outdoor unit. And then you manually choose the proper choices to get the control functions mapped correctly for your system. That went quickly.So the lady spent at least 20 to 30 minutes on the phone with me walking through all of these.Lastly, is the actual temperature setting. At first my temperature readings seemed to be way high and I had to apply a -5 degree offset via the phone app settings to get the temperature in the neighborhood. I had my old t'stat and a kitchen digital probe nearby to compare those readings to the new t'stat. I would say after about 24 hours of use, and the next day, the numbers dropped on the Sensi to where I had to then remove the offset entirely and back to zero, and now it's right on the money. I do like the new auto change feature that will come in handy in TX with 40 to 50 degree temperature swings in the fall and/or spring.If most of what I said seemed scary to you technically, then I would certainly recommend you get an HVAC pro to install it for you.

5.0 out of 5 stars Sleek, simple and amazing value for the money (I’ve worked in HVAC for years)

I worked in HVAC for some years prior to entering the new field and have installed my fair share of thermostats. Recently purchased a house and it came with an Ecobee 4. Had nothing but issues with it. Would crash randomly and take up to 25 minutes to reboot, and in general does not carry ease of use.Now onto the Sensi touch. Amazingly simple to install and wire, the app even gives you a guide so you can designate what your previous wiring was at the terminals of the thermostat and it will automatically reconfigure and give you a 2-D diagram of positive wire up the Sensi using your existing wiring. Once wired up, I finished registering in the app and was able to control my thermostat remotely on my phone. Both of the app and the thermostat itself are quality, sleek, simple and is incredibly easy to use. I know there are a lot of high tech options out there, but if you are looking for something that is easy to install, reliable, and really offers most of what you would get when spending several hundred dollars on a thermostat for a flat $100. I highly recommend it.

5.0 out of 5 stars This is the one to get

This is the thermostat I wished I would have had all along. Easy to install, easy to read and good looking. The app is great and has a lot of features that I haven’t seen on other thermostats I’ve owned. The temperature settings are right on out of the box but you could do some minor tweaking if necessary.I find it very attractive, I bought the brushed metal unit.I installed it a month ago and not once have I had any connectivity issues; rock solid app. My wife and I have the app on our phones and they both work fine; you just need to share the same user and password is all.I like that the display dims down enough to be able to see it ok without it keeping you up at night because it’s too bright.One of the features I really like is when the furnace is actually running the display background turns orange on the unit and the app. I think it turns blue when the ac is running.I’m really impressed with this unit and recommend it to anyone. The directions are very clear and easy to follow so pretty much anyone should be able to do the install.

I already had a non-smart programmable theromostat, which worked fine, but was nearly impossible to read unless you were inches away, with the room light on. I like that this one is easy to read from across the room (with brightness controls), or right on my phone. Also very convenient to be able to adjust the temp from anywhere and set a reminder to change the furnace filter. Excellent installation instructions! Overall….very happy and would recommend.

I purchased two Sensi thermostats since it was getting close to heating season and one of my old thermostats died. Sensi was top rated on many sites so I found the best price at the time on sale on Amazon.These are very easy to configure. You can set up lots of schedules and quickly adjust the temperature on the phone app.I did have an electrician do the installation because I did not have a c-wire on the old thermostats. But she simply did the installation and tested it. She said she hadn’t installed this brand before but was very impressed with the quality and ease of installation so she planned to recommend them in the future.I set up the WiFi connection, all the schedules and options in no time without reading instructions because it’s very intuitive. You can change the brightness, set it to dark for nighttime, and quickly adjust the temperature by touch. They’ve been in use for a couple of months with no issues. Highly recommend.

Very easy to use

So far this thermostat is working very well as a replacement for an old-style analog Honeywell. The touch screen is easy to use, setup and home network integration are a breeze, and it easily connects to Apple Home. The Apple Home app functionality is very basic, but I like having the ability to run automations or use voice commands with Siri. The Sensi app on the other hand has a lot of features, and is well-designed with a pretty intuitive user interface. It’s only been a couple of months but I’m very happy with it thus far.UPDATE: It’s now been over a year. I have had no issues at all. The only time it drops connection from wifi is when the power or internet go out. The app is just amazing. You can do a lot but it’s not clunky or confusing. They just keep making it better and easier to use. One of the best smart home device apps I have ever used. I hardly ever use the touch panel.

Niet geschikt voor gebruik binnen de EU

Dit product is niet geschikt voor gebruik in de EU. Probleem begint al bij het registratie proces, daar loop je vast omdat registratie alleen voor USA en Canada mogelijk is. Het alternatief (Apple home) beschikt niet over alle functies voor optimaal gebruik en functionaliteit. Programma’s (schedules) maken is onmogelijk. Door registratie problemen werkt deze thermostaat (zonder schedules) alleen binnen je eigen netwerk omgeving en niet buitenshuis.(Middels Apple apparatuur geprobeerd het draaiende te krijgen)
