@kevin1 yes it’s DC circuit board that switches DC motor. Do you know why it’s tricky to detect by any chance?
@yermiychyk,
With an AC garage door drive, the line-in pretty much connects directly with the motor so Sense “sees” the signature of a motor activated by a relay/switch. With a DC drive, the line-in looks like an AC to DC power supply that could be in a million different types of devices. Right now, Sense just looks a a very short, maybe half second signature, to determine what kind of device is turning on - the signature for your opener likely looks closer to big desktop computer turning on, than an electric motor.
Found mine in just a few days. Chamberlain
Old, power hungry garage door detected while the newer more efficient has not.

My garage door is one of the few things Sense detected. It doesn’t use much power but I know exactly when my daughter got home at night!
