Sorry, made mistake,

My domoticz is running on a Raspberry Pi3+.

Installed Debian Buster on it, and installed Domoticz 4.10717 on it.
OS runs from hard drive to spare the amount of read/writes to the sd card.

As earlyer mentioned, everytthing runs smouthly, but SDM72D-M wont..

Anyone a hint ...
