I have a liftmaster opener with a garagemote installed. I discovered that the "lock" mechanism can be triggered by applying a 22mf capacitor across the 2 leads for about 1 second, and then turn it off in the same way. When the opener is in a locked state it fluctuates the voltage across the 2 leads, which makes the LED on the wall button blink. I was thinking about ways to add this to the garagemote, but I am not sure how. I don't know if I would need to use another relay to insert/remove the capacitor, or if a transistor would work? Also, I am unsure of the available pins on the moteino. It looks like D3 is unused, and maybe D8 since I don't have flash installed. I think I could use something similar to a battery voltage divider to detect if the voltage was stable to determine if it was locked or not, and I think A2 and A3 are available for this. Ultimately I'd like it to lock the door at night and unlock in the morning. Any help would be appreciated! Thanks.
