Tell us about yourself!
@mdshann I understood that. I've this implemented solutions myself. I detect the garage state by tapping into the limit switch inbuilt into the garage unit. The belt/chain triggers this inbuilt limit switch and that's how the unit knows when to stop. We can tap into this existing mechanism to detect the state.
@Angi1 Give particle.io a try. $20 Wifi cloud connected and managed board. As for detecting garage door state, garage openers already keep that state. Check if the chain/belt triggers some switch upon stop.
