Programmable Smart WiFi Thermostat Plug Outlet, Wireless Electric Plug-in Temperature Controller with App Remote Control. Compatible with Alexa and Google Assistant

I bought this to control a through the wall fan between living room and bedroom, move warmer air into the bedroom when temp drops below 67F or so. It works well for this. Off a degree or two but easy to compensate. The issue was the hit and miss owner manual. I spent almost an hour trying to figure out how to simply make the temp show in F instead of C. I succeeded only after finding this information in the Amazon listing. Beyond that, the instructions read like “push a button (there are two) three times then hold the “other button” for 10 seconds, then push a button three times, then stand on your head and make a noise like a chicken”. It took me an hour of frustration. I copied this information by a screen shot from the product listing. FINALLY i got it working. UPDATE 2/23: It does what it’s supposed to. BUT IT SUCKS BATTERIES. 6-maybe 8 weeks from a pair of alkaline AAA transmitter batteries. The transmitter doesn’t require reprogramming on a battery change. AAA batteries are inexpensive. Just sort of a nuisance to change them 2-3-4 times every winter. Leave the receiver plugged in. That way you won’t. Need to re-pair from scratch on a battery change.

The design of the outlet on this is such that it doesnt hold a plug well. Because of that the plug backed out and the heater I had plugged into it never came on. Luckily, that didnt matter much, this time. It does sense the temperature and turn on and off like its supposed to, but without tying the plug down where it cant fall out of the outlet, that doesnt matter much. Im pretty sure the house didnt move much while I was gone, so I dont think it was shaken loose. It wasnt where any critters could get to it, so I dont think it was knocked loose. Im pretty sure it just fell out, because the outlet simply doesnt hold a plug in place.

Nine months later and still working great

Love this item. The Thermostat works very well. I use the plug + thermostat settings to control my babys wall-mounted plate heater and this helps me control the temperature in his room and save a noticeable amount of money in my electricity bills. Recommend it 100%.

The probe doesnt work, even though Ive plugged and unplugged the probe, reset factory data in the device settings, then also removed the device entirely from the app and reconnected several times. It then displayed simple thermostat and said it was 34 Celsius but then the probe shows so responsiveness to temp changes like the heat of my hand or blowing on it, not by even 1 or 2 degrees. I have a mercury thermometer in my room to cross reference

It doea exactly what it says it will, very easy to work with.

I bought this in an attempt to regulate my window A/C more effectively. The A/C thermostat was either poorly functioning or just in the wrong place (i.e. on the machine itself), so the cooling never began or ceased when it was supposed to. Finally, with this device, I can keep the room at a sensible temperature. I agree with the critics who feel the user interface and instructions could be better, but I was able to figure out and am very happy with the result.

I use these to control a couple of electric heaters in my garage. To my surprise I discovered that two switches could be operated by one controller. The temperature reads five degrees high. When the unit reads 55 degrees f, it’s actually 50 according to numerous other thermometers

Took quite a while to research how to get it from C to F for temp reading... finally found incorrect directions on how to reset and program it to F. Using the incorrect instructions, then trial and error we figured out how... the unit is also supposed to display the battery strength - mine does not. Given the bad reviews on batteries not lasting, this is an important missing item.... Ill give it a shot anyway - see what happens.....

Should come with day/night control if did would rate 10/10
