@Jan-Gatzke The Log Parser says the payload type is P_INT16 so I would expect a number. It is also unclear why V_VAR1 to V_VAR5 on every senor appear.

I made some test of the latest development branch 2.2.0-rc1. The RFM69_RFM95_ATC_SignalReport.ino got six Custom Values (V_CUSTOM) which are not correctly shown in ioBrocker and the values are empty.
The adapter version is the 1.0.10.
Here the log of my sensor:

Other sensor values like V_TEMP for example are represented like expected.
