RFLink pairing lost

[RTSnewbie]

Hello!

I am new here, please excuse the silly question.

I managed to pair RFLink with my Somfy RTS shutters successfully (rolling code). However, I have the impression that the pairing was lost suddenly. I re-did it, it worked again and then was lost again.

Is it possible that this loss is connected with the power supply of the RFLink? I could imagine that I disconnected the RFLink module from power when moving it within the house for testing/pairing.

Any hint appreciated!
