The light on X1C is working again
Yes, i found the issue eventually which is a challenge lacking the model with the problem. Thank for verifying this both you and @xxJeroenxx .
Now we have version 1.0.8 live 
and compared to the last live version 1.0.3 there are both bugfixes and new features (several new trigger flow cards).
One very important bugfix is the one making the Chamber Light control (both from the read/write capbility ābuttonā and from the actions working also on X1C model.
