Man, sometimes I wonder if something is sending the same signals to the different parts of the planet we inhabit.

I've been spending time on a LUKS automation project too for some time now.

It's a great feature with the heartbeat! I did not think of that.

Part of the feature you're talking about could be geofencing maybe?

Heartbeat is not bad, but it is a method of detection or signalling something is alive. What about dead man's switch?
