Amazon makes one but to view data, it's app based and that's a dealbreaker for me: https://www.theverge.com/22971411/amazon-smart-air-quality-m...

Yeah, I bought one and am pretty disappointed by it. Not only does the Amazon app suck for looking at the data, but it has CO instead of CO2 for some idiotic reason.

At least it convinced me to finally figure out how to get my AirGradient working with Home Assistant.

measuring CO2 is more expensive than CO, a decent sensor alone would cost more than $20
