I’ve been fiddling with this for a while. I’m a cheap SOB, seriously, cheap, so here’s what I’m doing, and what I would like some hopefully better suggestions for:
- Car sensor to tell me if car is in or out of garage.
- Based on time of day and car presence, my arrival sensor will trigger to open the garage when I get home.
- Only when house is disarmed (wife/kids are home) between 2pm and 11pm for when I come home from work.
- Life360 working as my presence sensor on my phone.
- RM obviously does this as I have multiple conditions.
This all works GREAT except point 1 is a manual virtual switch I trigger on when car is home and off when I leave in the morning.
Due to my cheapness, I have no additional zigbee or z-wave sensors, I do have an unused Insteon contact sensor. I built this amazingly Mad Max contraption from two pieces of steel hanger (like garage door openers use,) zip ties, some motherboard standoffs, a Cisco AP hung ceiling mount plate, and some blood.
When I drive onto the steel hangers, they collapse and the magnetic portion of the contact sensor moves down to the floor where the contact sensor is strapped to the apparatus. It’s springy enough (for now) and does trigger.
Then I have the REALLY bad Insteon Hub send my gmail a notification that it’s open or closed (except closed doesn’t work as it sends to the wrong email) and ifttt parses the gmail email to turn on/off the Smart Things virtual switch.
I tested this morning, moving the car out, sent the email, triggered the switch YAY!
Insteon makes ST looks like a reliable, stable, platform, so when I drove back on the “thingy” it closed the contact but email went to the wrong address. Stupid Insteon…
Anyway, that’s what I’ve got and what I want, anyone have some drastically simpler solutions short of buying a new contact sensor? And even then, some better way to make a wheel pad or something to trigger it? Optical sensor was a thought, but that would be too unreliable, need a physical “the wheel is on the pad so the car MUST be here” kinda thing.
I did try just having wire’s that would move to make or break contact with a spring type device but the Insteon contact sensors are crap and don’t work properly with more than a few INCHES of wire attached to their screw terminals.
