I got a couple of Shelly 1 Plus units to automate my garage door and sliding gate motors. These new Shelly’s have a dedicated 12v terminal, and the units work fine wired up to my garage door, which supplies its own 12v feed. The AP publishes itself straightaway and I can connect and configure it in HA.
Both units also work fine with 240v. I’ve just tested by wiring up active and neutral and seeing the AP straight away.
I cannot get either unit to work on the 24V feed from my BHT gate motor though. I’m just wiring up the motor’s 24V aux + and - to the Shelly’s DC terminals but I get no AP. I’ve confirmed with a multimeter 24V is going to the Shelly’s terminal.
Is there something I’m missing with 24V DC requirements? Do I also have to wire the SW/0/1 terminals before the AP starts up??
Thanks in advance.
