@badnetmask This was a pretty good review of what's out there currently. https://m.youtube.com/watch?v=pAT1TCYY73c
@badnetmask My Aqara TVOC started acting flaky after only a few weeks. I had to keep resetting it. Eventually I junked it and upgraded to an AirGradient Pro. It's a lot more expensive but it's also rock solid.
