Quoting myself from the other thread:
The signature for the zwave "Multi Channel" class changed from V3 to V4. The implant documentation says that you should be using V4, I don't know why it was coded as V3 in the first place (seed design by "boblehest"). Maybe hubitat didn't support it then and was mapping V4 to V3 and in the last update they implemented V4?
I just copied the function
private zwaveEvent(hubitat.zwave.commands.multichannelv3.MultiChannelCmdEncap cmd) {
...
to
private zwaveEvent(hubitat.zwave.commands.multichannelv4.MultiChannelCmdEncap cmd) {
...
I also saw that the update changed the basicSet class handling, it might require some more changes in my driver.
No need to delete your post, I was happy to see such a fast first post
