Lux TQ1 Smart Digital Thermostat for Home, Programmable WiFi with Matter Protocol for Temperature Control, DIY Install, C-Wire or Power Bridge Required – Works with Apple Home and Google Home

It works, BUT has a 4-6F Degree discrepancy from TWO separate thermometers when screen is on.
I always wanted a Smart Thermostat but until very recently they were cost prohibitive as in not being totally worth the utility for me. Nest ranged between $150-300 depending on how advanced the unit was and Honeywell and others were just the old models with pretty much very rudimentary interfaces.For $94, this unit featured advanced controls with several unit types and more important, Matter Integration, so it wasn’t limited to a single “automation environment” so it’ll work with Google Home, Gemini, Siri, Alexa and many other automation protocols through the Matter umbrella, that’s the Number 1 feature for me aside from being almost 40% cheaper than the cheapest Google Nest.Installation was as simple as it gets, instructions are well put and while i am very experienced with HVAC, Electric and overall Home Maintenance work, i feel pretty much anybody can do this, as long as they have a Common Wire available, and it’ll be most likely available in home built recently, if not, well you might get it done if you’re crafty enough, but if you don’t feel comfortable then you might need a technician, however that’s not the product’s fault.Everything works as intended, the screen is bright and easy to ready, and that may be part of the issue on why it lost a star, more about that in just a second.Connecting it to the App and integrating it to my integration protocol was as simple as it gets too, just like setting up a smart light or a smart lock, operation is quick and flawless and connection to my WiFi network was seamless.Now, the downside is that i felt that the AC unit was running A LOT more after i changed the Thermostat, i was wondering why and also felt that the house was feeling a little colder too at the same set temperature, i have a thermometer in the kitchen and one in the main bedroom and those always matched the thermostat or were off by no more than 1-2F when sitting in rooms different to the thermostat, so i brought one closer to the thermostat and there was a 4F difference between what was set and what the room temperature actually was, brought the other thermometer, same result.My conclusion is that by placing the hand over the screen when lit, it emits heat, NOT A LOT, but i assume that its enough to throw the measurements off, maybe they tested it in a lab and at certain specific temperatures in a controlled environment it was calibrated, but temperature is a tricky value, pressure, atmosphere and even humidity can affect heat retention inside a wall is the heat emitted is enough, i am not talking about thermal perception, but actual physics, so unfortunately it is not perfect, i am hoping that after some use it may have some learning, or software update, or that the sensor recalibrates, because that’s what the main functionality of a thermostat is, being as accurate as possible.Overall i like it aesthetically and functionally does everything i needed to do, the accuracy is an issue, maybe i got a lemon, i was debating myself between 3 and 4 stars but so far i like it and i hope Lux pushes an update to fix this issue.

Easy to install, easy to use, won’t activate my compressor
This was very, very easy to install. The instructions are clear, and it was a breeze to hang on the wall because of the built-in level. It connected to my Wi-Fi, and I was able to scan a QR code with my phone to automatically connect to my Apple Home app. It’s easy to control from the unit and from the app. Sadly, it ends there. No matter what I did, despite turning on the AC through the unit, my compressor never turned on, and cold air never blew. I checked all of the wires and connections, and made sure everything was connected and turned on. Even my HVAC guys were confused. It’s not really worth much to me if it won’t control my unit. I’ve had to un-install it and re-install my original thermostat.
