Anyone elses sensor in my setup

[rvenes]

Hello...

Im using Tellus net
I've discovered another sensor in the sensor view.
It's doesn't bother me if it had worked, but last check in was 2 days ago!

And i also have another sensor that i tested, it's been offline for 10 days almost. This is the Clash Ohlson transmitter that only transmitt 1 signal, internal or external signal, now i have connected the cable and only the external is beeing updated.
When do they go away? or do i have to delete them?

A sensor which hasn't been updated for approx one week will automatically be removed from the sensor list.
