I would love if AirGradient had radon! For now I’ve been using a RadonEye with the jdeath/rd200v2 HA addon along with some POE esphome bluetooth proxies. I find the RadonEye is more reliable than my Airthings units.
Yes, I’d like to see an Ethernet connection and PoE support for future indoor and outdoor units.

Same. TBH radon detection is a priority for me living in Minnestoa and I can’t imagine spending hundreds of dollars on a sensor missing this.

Glad to see the influencers @geerlingguy and @technotim chiming in on radon. 
as someone in the northwest hills of Connecticut, it’s a concern here as well.
