Comfort Zone Living Comfort Smart Wi-Fi Reversible Twin Window Fan with Removable Cover and Bug Screen, 9 inch, 3-Speed, Expandable, Timer, Compatible with iOS/Android/Alexa/Google Assistant, LC310SWT

Work great. GF’s said to “how did you hook a fan up to Bluetooth?”, “Amazon “3 speeds and can cool, exhaust or circulate.

I bought this fan to integrate with Home Assistant to control air flow into a sunroom. It is recognize immediately by Smart Life once plugged in. Using the official Tuya inegration, only on/off is exposed. But if you use the "Tuya Local" integration, you can control everything, including fan speeds and modes.It works quite well for its purpose. The noise level is on the loud side, around 48db at low setting and 54db at high setting. There is some humming from the AC motor. But I think that's true for most window fans. I will probably put some more padding around it to reduce the noise a bit.

Works as advertised.Airflow is less than expected, but i use as exhaust fan on low, in a window, near the cat box. Works for me.Little louder than expected but not so much its a problem. On low setting and in other room you can't heat the fans, maybe just a little.The left and right expansion wings need to be just a little wider. One inch each. Will 3D print an extension and be all set.The wifi works good. I used Smarthome app instead of one recommended with the fan and it was visible and setup in under 2 minutes. Alexa recognized on first try. Not a lot of options, but it's a fan. Off/On, Mode, Speed.I plan on keeping it on low all the time, so maybe didn't need wifi, but it's there and working.Would buy again if needed for another part of house.

The sides could extend longer. Moves hot air quick

I bought this for its WiFi function. I already had one from different brand with exact same dimension and almost identical to the model with remote but no WiFi. I put the fan in the window in the our bathroom in master bedroom. In winter, we close the door and all windows in the room in night except for the opening of window to accommodate this fan. It serves a few functions. 1st, clears out the moisture inside from shower; 2nd, get cool air from outside during summer; 3rd, get fresh air from outside to reduce CO2 inside.The fan functions mechanically identical to the one I had without WiFi. It’s a decent fan. However, with WiFi, it can run automatically when the situation calls. It supports the Smart Life app available in both iOS and Android. I had the app already connects to sensors (a CO2/temp/humidity sensor connected to a Bluetooth gateway compatible to Smart Life), I can set the fan to turn on (at desired mode and speed) during night time when the CO2 in the room exceeds limit (I choose 1200ppm), and turns it off when it drops down to lower level. Now it automatically runs to refresh the air during the night and shuts off itself when done.It works really well, and you can do similar setup with temperature or humidity with sensors compatible to the Smart Life app.By the way, although it does not come with remote. You can easily use your phone anywhere in the house or just ask Google or Alexa to turn it on/off. I highly recommend to purchase WiFi model instead of others.
