    What an adorable little bag in pristine condition! It’s exactly as described (small but roomy enough for essentials with a fun summer print), was shipped promptly, and was packaged well with attention to detail. Plus, there was great communication from the seller. These are quality bags that aren’t easy to find, especially this reasonably priced. I’m thrilled with the buying experience from start to finish. Thank you so much!

    Ok and budget choice

    I had an American standard thermostat, made by the same company obviously, as the sensei wifi stat was exactly the same base etc. I snapped it in place with the old base, took a minute to install. The features of the app are ok, but some are reserved for the website that your have to pay for, which is annoying.

    Not worth it for me.

    Was VERY hard to get it to connect to WiFi and instructions were ZERO help. Had to search and seach online and on YouTube. A one hour install turned into about 8-9 hrs over 2 days. I don't use my thermostat much and when you put it in off position, you can't use Alexa to turn the unit on. If it's on, you can raise or lower the temperature and that's it. So, I'll be using it manually all the time and I could have gotten a different thermostat for that for half the price.

    The best WiFi thermostat for simplicity and value!

    I have installed 3 Sensi WiFi thermostats so far and this one I purchased on EBay will make #4. I also have an Icomfort and Nest that I use as well for my home and rental properties. I also tried to install a Honeywell but I had to take it back. I do have considerable experience with using these. Very simple to install and hook up to your internet. The App screen shows me 3 units at a time. One rental house has two HVAC units and two thermostats so this is valuable to check. The biggest bonus is all WiFi thermostats measure the humidity in the house. Anything over 70% causes mold and this Sensi software allows for humidity settings to run the air or heat automatically to decrease it. It even sends me an email when the humidity exceeds 70%. This Sensi unit also keeps track of the ...

    WIFI integrated thermostat that does not require a "C" wire

    One of the few thermostats that will hook up to wifi that does not need a "C" wire. I go away for the winter and will be able to check my home to make sure the furnace is working and adjust the temperature. I can set a schedule for each day of the week with up to four events during each day or I can let it sense that I am home, probably through my phone app, and if I am not it will set the temp down three degrees and raise it back up when I get back home. I wish that I could use both of these together because I set the temperature down at night. it does it without fail. It also keeps my temp at the set point. It does not go down two or three degrees and then come back up to set temp. I have had a couple of different electronic set back thermostats before but this is much easier to ...

    Thanks again for an excellent product and easy to install

    We found your thermostat to be entirely simple to install especially after having some experience with a Google thermostat that was a monster to do anything with. It sounded simple with all the squishing and pollen but yours is ideal it works beautifully we're so happy with it. The wireless works just beautiful I can check my temperature from anywhere from my cell phone within 1 mile or 3000 miles. Thanks again for an excellent product and easy to install
