It’s not so much that something is missing, more that too much is included, without and checks against firmware numbers.
Parameter 38 never used to exist, but it was added at some point with a firmware update, so for older devices running the old firmware, parameter sync fails due to that number not reporting a successful update.
I’ll take a look at the DTH this weekend and If i can figure out a way for it to work for new and old firmware, I’ll suggest the necessary revisions. It’s certainly possible to get Fibaro modules to report firmware version, so I just need to write some code around that.
Are zwave OTA updates ever likely to happen?
