Useless device. First, it spams ZigBee net with 2-5 messages per second. So, adding 2-3 devices to your zigbee network will make it irresponsive. It also has over-aggressive calibration with leveling the CO2 to 365ppm in ~20 minutes, even if the real concentration is 1000-1500. It reports formaldehyde level as 3-5 on free air. I left devices for 1-day to be auto-calibrated, but all of them still report inadequate Co2/TVOC/formaldehyde values
Temperature/humidity/pm2.5 are reported correctly.
