So I'm thinking of using a using the RR-VCRX with a 3rd party automation system. I'm wondering of the best to get the transmitter's home and away buttons to trigger my 3rd party system. The RR-VCRX output would work if its a latching relay, I dont want it to open or close on a power loss. Or can I trigger a phantom button on the main repeater from the visor transmitter? I don't have the hardware to test this ATM but looking at the RA2 software it seems the transmitter just talks to the VCRX. Ant thoughts? TIA
