I have a new garage and extension being finally completed in the next week or so, so getting everything nice and automated.
I have a Smarthings hub which I used for basic lights + Arlo security at the moment, but the garage door opening will have a Somfy Tahoma system and Somfy opener.
I’d like to have the doors open automatically when I arrive home, but I don’t want them opening all the time - so whilst I could do this with a presence sensor, I want it to be more clever than that. Daughter is 8, and if she works out she can open the garage by tripping a beam sensor or waving my phone or keys outside she’ll be doing it all the time! Am relatively new to automation, but can work most things out if I can get a few hints.
So far i’m considering:
Arduino ultrasonic proximity sensor in the garage itself: can tell me whether there is a car in the garage first. Also allows me to put something like a LaMetric LCD display at eye level when i drive in to tell me whether I am close enough to the wall (car doesnt have front parking sensors)
Life360 for presence. I guess I could use something like Webcore to make it triggers only at more likely commuting times of the day, but still worried there will be too many false positives. There is a village pub 200 meters from my house, so am often sneaking off for a pint - don’t want the garage door opening if for whatever reason I’ve not parked the car in the garage before! This together with the above will likely be my solution - but doesn’t feel 100% fool proof
Velleman photoelectric beam sensor. Could put in front of the garage itself, so expands potential data sources to allow me open only there is no car in the garage, i am home,and that beam is cut. This would remove most false positives- but does mean I have to wait a few seconds for the garage to open if the beam is close to the door. Whereas in my mind at least, the door is opening as I pull into my drive and open by the time i’ve made it to the garage entrance!
What other ideas to create a fool proof system for opening the doors when I return? If there any way to use data from Life360 to flag only if i arrive at a certain velocity for example…? Doesnt feel likely but am sure some very clever people here have better suggestions than I’ve managed to come up with…
