If I look at https://developer.athom.com/tools/zwave and enable the logging I see a lot of ProcessSendData and isFailedNode entries. When Homey is slow on z-wave (or sometimes not even responding) the Current Process constantly lists ProcessSendData. PTP resolves sometimes, but sometimes I just need to wait for 30-45 minutes before z-wave gets kind of stable again (responsive). Still on a regular base the ProcessSendData and isFailedNode entries are listed in the log. Does anybody have a clue on what is happening here?
Homey is on current stable 1.5.12 release.
