Controlling CO2 levels in my home cinema

I recently bought the CO2 module to fit in my EP Lite . I bought it as I was concerned that there was inadequate ventilation in my dedicated home cinema room. Sure enough I found that the CO2 level in a evening quickly got up to over 2000ppm. I have now fitted a ventilation fan, and with the help of HomeAssistant, a relay and the CO2 sensor I am now able to keep the CO2 levels at a comfortable level, The add on module installed with no issues, and for the price it is by far the lowest cost option for a CO2 sensor if you already have the EP sensor. I ordered it at 2:30pm one day and it arrived the next morning in South Wales at 11:30, that even beats my local Amazon service.

really good qualit

really good qualit, very easy install. The only point would be to include better instruction for pin installation - as the device has 4 pins but you plug into 6 so you want to not miss out on that.

EP1 CO2 Addon-Exceptional

A most excellent CO2 add-on device. Especially since I can add the CO2 sensor to my existing EP1 device(s) and I do not have to have "another separate sensor" device in the room. It was immediately seen by HA, and I am now working on automations based on the sensor data. Looking to purchase additional sensors for my other EP1s. Highly Recommend.
