Additional info:

This worked fine with the 0.41 container, and apparently still does since someone else said they'd rolled back and it fixed it. I haven't rolled back because I want the shiny new Ring stuff. Forum discussion here: https://community.home-assistant.io/t/alarm-com-broken-since-upgrade-to-0-42/15346

Please open a issue on pyalarmdotcom and ask for aiohttp2 support. We can not fix that.

Looks like it is fixed in pyalarmdotcom 0.3.0: lorddaren/pyalarmdotcom@763fc77

[jordemort]

Yeah, I was able to hack a fix for it by upgrading pyalarmdotcom in the container (something like docker exec -t -i {your container} pip install --target /config/deps --upgrade pyalarmdotcom and then restart your container, if anyone else wants to hack theirs until it's properly fixed)

[jordemort]

Ah, this is the actual fix for it, guess I should have looked at the PRs as well as the issues! #7021 (thanks @Xorso :D)
