Is there any way I could trigger a push/pull setup in my basement's small windows w/12v fans when my Radon readings go above a certain level? (does Airthings have an API or integration thing? probably. hopefully).

I'd love to hear "oh yeah. just stick these two things together in Home Assistant" so I can kick my ass in gear and get that running too.. bc I do think I need it for other things too and I just haven't had enough of an urge..

@EricMalves am I gonna need an esp32 or something to help turn on some 12v fans? or is there some even easier way of doing it. I'd rather not have to use a "smart outlet" to control the power supply of a fan.

@colinstu @EricMalves i mean... how else are you supposed to do it? it's not like home assistant has the ability to control the power of literally anything that isn't connected to your network, it can't cast magical spells lmfao

best you could do is human intervention, where home assistant sends you a notification when the levels are getting high, so you get your butt up and manually turn on the fan

and that is a thing you can do, since home assistant supports sending notifications to your phone, but idk how to do that lol

@EeveeEuphoria @EricMalves could it turn on and off a USB port on a computer somehow? Is there an app I can install on some OS to have it turn on and off a port as it's told? I can power the fan via that. That's my dream.

Or an esp32 w/ethernet so it can be hardwired, and I can control GPIO/relays for fans that way.

@colinstu @EricMalves i mean, with a lil bit of programming that USB stuff doesn't sound infeasible

...but also yeah there exists ways to get esp32 to talk over ethernet instead, plenty of people have devised solutions for that

@colinstu You can use ESPHome to easily connect an ESP to HA. My smart outlets actually run on ESPHome

@EricMalves yup, was already having this one in mind too. Good. so I'm not crazy / this should just work..

@colinstu @EricMalves I have my bathroom extractor fan plugged into a smart outlet up in the ceiling cavity running Tasmota and controlled by Home Assistant, so it's definitely possible
Show threadColin10h ago
@TerrorBite @EricMalves I thought of using that fan too. But I like the idea of only pulling the air out of the basement, as the air is much less conditioned, so it would be cheaper to lose cold basement air vs heated/cooled house air.
Plus, most of the Radon infiltration is from the basement anyway, if I can evacuate it from there then it won't have much of a chance to get into house. (and I've confirmed w/sensors)

@colinstu If it coincides with humidity and water from rain is there a way to use that as the control element?
Show threadColin10h ago
@DeltaWye I’d rather it be reactive than proactive.
It all happens so fast / at the same time anyway. I don’t think much would be gained.

@colinstu Yes, airthings works over ble in homeassistant.

@colinstu OOf.. That looks like some kind of remediation needs to be set up for sure. We've hit a little over 3 once, but otherwise we're in the green here.
Show threadColin2h ago
@Zelus I’m not a fan of standard remediation methods and just plan to do DIY something myself.
But yeah I’ve long-known we are sometimes over what’s acceptable. Don’t have spoons to deal with it though. But just may finally.
