Revert from OH3.1M4 to OH3.0.1

I upgraded from a running OH3.0 to OH3.1M4 because I was not able to install the Modbus binding on this version. No problem with that on M4.
But now I had to step back, as the Zwave binding did not work under M4. After approx 1/2-1h the stick went offline. Errors as “ZWaveNodeInitStageAdvancer: NODE 21: Error in initialization thread”

Update: I tried the current SNAPSHOT and with that Modbus & Zwave do work.
