Thank you for your reply.
Made a clone of the SD cart and yes, it worked. Just inserted the SD card, Connected the ZWAY Module and powered it on - perfect.
The PI4 is way faster then the PI2 - so it was a great success.

How can We I easily change my R2 with a new R4?
Does it work to just place the SD Card and the Zway-Board into the Raspberry 4?

I would like to avoid having to much effort for this Upgrade.

Is it possible that the Raspberry 2 just have a bit too less power for all situations? In total a currently have about 30 devices registered - most of them W...

Since I updated my Controller (Raspberry2) to 3.1.0 the CPU usage is always about 100% with the z-way-server and reaction of the entire System is very slow.
Anything I can do to bring the usage down?

...did the update yesterday from the commandline - worked.
Looking forward how it is ...

Coming from version 3.0.6 I run the Update to 3.0.10
Basically works as expected, say done successfully but after restart it still shows the Version 3.0.6 and recommends to update.

Today I did the Update to 3.0.5
I was happy to run and expected the the Z-Way Control App now works.
But sadly it dosn't- same Situation as before.
Is there anything beside the update I Need to do to make it work?
