15-in-1 Air Quality Monitor with WiFi & Mobile App - Detects CO, CO2, HCHO, TVOC, AQI, PM0.3-10, Temperature & Humidity - Digital Alarm Clock with Timer & Alerts (White/Red) for Home, Office & Baby Room Air Monitoring

I saw this on sale, so I thought I would give it a try. I was content with it, at first, but the main issue is that it stopped working after about 6 hours. It just turned off, and when I tried to turn it back on, the screen would only stay on for about 2 seconds before turning off again. I am getting a replacement to try again, but I don't have high expectations. I wanted to use this with Home Assistant, and I was pleasantly surprised that you could with the Tuya app, but not all of the sensors are supported, for some reason, which is curious. I wish there was a local interface option, as I'm not thrilled with opening up my home assistant to a Chinese app, either. That said, I was content enough to try to get a replacement.Edit: My replacement has worked for over 24 hours, so I am updating my review to 3 stars. I'm taking off two stars for the very bad app interface, lack of Home Assistant to be able to view all of the sensors, and the lack of a local interface option for data recording. You really need to view sensor data like this over a long time period for it to be useful and figure out what is causing your air quality to diminish. This does have an alarm function, so I suppose the intent is to just detect extremely bad issues that require immediate attention. I disagree this is the correct approach and I was hoping for more.
