Using Extended Codes and Addressing Transmit Commands With CM15A

[Puck]

Why not just set up a timer to call a macro that will send the arm signal once at midnight?

Be aware that there is a bug in OnAlert that when you arm via a macro, the OnAlert Armed / Disarmed conditions are not updated. This only updates when OnAlert receives an RF signal from a registered security remote.

If you want to have the door's sensor trigger the macro once, then maybe use a status flag as a condition instead of the Armed / Disarmed condition.
