I have a garage door opener which has a operating range of about 10 feet. It uses RF signals to trigger the gate, and it poses a couple of problems.
- Range is very limited
- You have to wait and verify that the door closes before you leave.
- Sometimes you are unsure if you even closed the door.
So, i decided to get a new app controlled door opener. That was until i checked the prices. Its 2000nok for a commercial one, with 1 door sensor. To me that sounds like robbery, so i decided to make one myself.
