  • Motor voltage wasn't tested yet, but I would expect they have force switch since this is a legal requirement for door motors to lift the door if they encounter some force downwards like an object stuck underneath.Again, this is intermittent, so it could work without issue during tests, and not afterwards...

    I was told the modules fail to work, but they all do, as far as I could test them. There's a second garage door opened by the same brand of modules that show no problem, so I doubt it would be an interference problem. I wondered why he never used a standard key + lock to make the door open, but I guess it was easier to fit a remote module on an existing motor than dig a trench, lay cable conduit, make a hole in the wall. So RFID would require the same kind of heavy job. And he doesn't trust the tenants to handle anything electronic carefully, and RFID cards are prone to breaking.The only logical conclusion would be the motor, or the cable fitted from the module to the motor. The modules already have a dim LED on them telling wether they received the signal. I could add a very bright LED...see more »I was told the modules fail to work, but they all do, as far as I could test them.

The modules already have a dim LED on them telling wether they received the signal. I could add a very bright LED wired to the outside to check the module is actually working. But since this is an intermittent problem and therefore hard to debug, maybe something to log the state of the different device (receiver status, motor status, switch status) would help? How would this kind of circuit be called?
