@grahamguy Ah, I see what you mean, good point.

@grahamguy And these would only need to ping maybe a few times a day. Maybe increasing rate if there’s more motion detected.

@grahamguy The math is beyond me. Conceptually I know it sounds like it should be possible, but I know little more than the concepts.

@grahamguy A cheap solar-light style PV panel would probably be enough to keep a BT radio running for a long time. Garden light chassis.

@grahamguy That’d be the sort of thing I had in mind. Something that could be dropped like lawn-darts from a distance. Cheap & hands-off.
