The verdict is not out, yet

I'm not sure if this CO2 meter is working correctly - it reports huge spikes (all leds on, default threshold setting) at times when no CO2 spike could be expected (e.g., no occupancy, ventilation running). I will try to calibrate with another unit and report back.

If you think you need it then buy it.

Safety first! This thing works very well for automating exhaust to remove CO2. Very important because you can’t smell or sense CO2 to get it out of your workspace. Somewhat complex to setup but worth the safety feature.

Good for home

Keeps my house in the desired range for CO2 by running the HRV system using the relay connection. Range is adjustable.

"Easy to install, easy to set up, and easy calibration - just what I was looking for."
