Heartbeat signals
Posted: Sat Oct 11, 2014 3:17 pm
Hi all,
I'm using several DS90's with my RFXTRX to receive the status of my doors.
The DS90's send a signal when the door is opened or closed, but they also send a heartbeat signal every X minutes.
When the RFXTRX misses a 'real' signal, the next heartbeat signal of a DS90 causes an action to start.
I.e. turn on the hall light if someone opens the hall door.
Is it possible to technically recognize heartbeat signals from 'real' signals?
Thanks!
