I just migrated from OH2 to OH3 and my system seems now to be very slow in seeing state changes of ZWave on/off sensors. Problem is that my upgrade path was rather complicated, so I am looking for tips about where to start. My main goal was to migrate from OH2 to OH3. But I thought it would be coo…

@Andrew_Rowe @frankb @OMR thank you all for your suggestions about using the ZenSys tool; some initial feedback as follows.. I used the Aeotec version of the ZenSys tool (just to avoid the mentioned hassle with Silicon Labs logins). The Aeotec web page is here , and their direct download here . (no…

^ Ok. I have ordered a high quality USB 3.0 cable rated at 5Gbps. I will let you know the result when it arrives.

In the mean time, try the USB-2 port. Datarate is very low.

An interesting post about Pi4 interference on USB ports here.. [image] openHAB 3.0 Milestone 2 discussion News & Important Changes Backup causes me a day of extra work. :-o You wonder how ? I did the backup, reconnected the SSD to my RPI4. But instead of the U…

@OMR @Bruce_Osborne The Pi4 specification says.. All four USB ports on the device are connected to the USB 2.0 hub, whilst the USB 3.0 ports (blue) are ALSO connected to the USB 3.0 bus via the USB 3.0 specific pins in the socket. I think this means that a USB 2.0 Z-stick will always connect vi…

But the stick misidentifies itself as USB3.

[image] Bruce_Osborne: the stick misidentifies itself as USB3 Does it? Physically the plug seems only to have four pins inside..

I intuitively always connect USB 2 devices to USB 2 ports and USB 3 devices to USB 3. :smiling_face:

ZWave: system migrated: on/off sensors now very slow
