Ive just started the rabbit hole and Im wondering about CO2 automation. Atlas scientific makes a CO2 sensor, so Im wondering if it can be utilized? Then some kind of solenoid to control the regulator? I know I have research to do still but all this should be possible to automate through HA right?
I have used this sensor with success in the past

I used a smart plug that I had laying around to trigger an air solenoid similar to this one.
1/4inch DC 12V 2 Way Normally Closed Electric Solenoid Air Valve
Just make sure it’s normally closed and play with the automation, I think I had it trigger for a few seconds then wait for several minutes until it met my target PPM’s

Thanks man! way cheaper than the $150+ Atlas C02 sensor
i just ordered the Atlas CO2 Sensor that is compatible to Tasmota ,i will have news soon :

i have the PH and TDS already working on Tasmota/HA , including the calibration .

Good point about Atlas quality. I look forward to hear about your sensor set up when you finish. Ive never heard of Tasmoto before, so more to research.
i just ordered it today , im in Canada so it takes a little longer receive it , most probably next week i will post here using Tasmota .jeffcourtneydba wrote: ↑Thu Jan 21, 2021 6:17 pmstud wrote: ↑Thu Jan 21, 2021 4:46 pmAtlas = Qualityjeffcourtneydba wrote: ↑Tue Jan 19, 2021 4:01 pmThanks man! way cheaper than the $150+ Atlas C02 sensor

to utilize EZO Sensors on Tasmota ,you most compile it , by default EZO sensors are not enabled .
if you want i have Tasmota 9.2 with EZO PH,TDS,CO2,RTD enabled on i2c , compiled by me for esp8266 ,i dont mind sharing .

i have good news on the Atlas Scientific EZO-CO2 sensor :
https://atlas-scientific.com/probes/co2-sensor/
worked for me with tasmota on a Wemos Mini D1 ( esp8266) .
