“I have a client who had a gated area where many people needed to come and go. They didn’t want to use a keypad on the outside and only had a limited number of keyfob transmitters. Finding an affordable source for additional keyfobs was difficult. I thought it would be a great opportunity to upgrade this Liftmaster gate operator to be IoT compatible with custom hardware, web API and web app interface. This not only solved the mass access problem it opened up additional functionality as well!
In the last photo above is the test unit that I had running for almost a year in a ziplock bag. I thought it was time for an upgrade!
This is a fully functioning solution with all code and designed listed here.”
