What I mean is that when I set the alarm from an orbiter, if I pick up the sensor from the table, the alarm sounds (due to the tamper switch), so that's fine and working as it should.
However, if I set the alarm, but separate the two parts of the sensor (simulating the opening of a door), the alarm does NOT sound.
For the dongle, the "Port/Channel number" is set to "1", is this what you are referring to? Or is the group thing different?
Cheers,
Matt.
