What does “zwave_serial_zstick_78e94ad2_serial_sof changed from 262 to 263” mean?
I notice it is logged (default level) each time I move the sensor. I can’t find any docu about it when googling.

Check out the docs :wink:

https://docs.openhab.org/addons/bindings/zwave/readme.html#controller-channels

Basically, SOF is the start of frames the binding is sending, and an ACK is the acknowledgement of a frame we sent.

thanks @chris. Great docu. I was yet guessing that “ack” was somehow related to network packages. I read it earlier, it’s too much detail to remember all.
I feel embarrassed because I could have consulted this again, but I didn’t find it when searching for it. Maybe if you could add some the separate words on this page like zstick, serial,sof,ack,nak, can, changed,… the page would show up better in search results. That can improve the level of self-service.

Many thanks!
