I’ve done that now and the log can be viewed here - it’s about 4Mb so give it a minute 
It’s node 12 that has the static values warning after upgrading to the latest snapshot.
I should add that the log starts with the “apt upgrade” and subsequent OH restart so the relevant messages are probably a bit further down.
After it all settles down, the following block repeats every 5 seconds in openhab.log:

UPDATE: This seems to happen everytime OH starts, not just after an snapshot upgrade. If I stop and start OH, the device displays the static values message, and if I delete it and rediscover it, it appears fine.
