Do you have an old security system cabinet with numerous “wired” door and window sensors which you’d like to see in HA without messing with “configuration.yaml” changes?
And/or
Do you wish you could monitor your wired reed switch (or motion) sensors in a way where you are more sure that “closed / quiet” doesn’t actually mean “lost power” ?
Do you also like the idea of knowing a door opened/closed wtihin 100ms of the event occurring?
And/Or
Do you have numerous, wired “ds18x” temperature sensors which you’d like to “autodiscover into HA”?
If so, guarduino may be worth a look.
I wrote this project to serve as an affordable, simple home-security hardware interface. Hopefully, this is useful for some of you as well.
