Is there any way to control if receiving is still going on. For example: a temp sensor show 3.4 and after half an hour it still show 3.4 and that can be OK but I am not sure. If I than could get any value every time I receive a signal that I can compare with like a time stamp it would be very good.
Can I do that?
I found a solution.
BatteryDate (Unix time) is changing when the device received a message.
Yes, that would be the solution, at least for devices reporting battery level.
