Philips Air Binding [4.0.0.0;5.0.0.0)

The ‘alpha’ version works fine, even it stopped with the latest 4.2 snapshot. Do you find time to cancel the verbose log because it spams the log with up to 8 or 10 repeated messages

yes, indeed time to clean it up.
I have myself also not found that it was working less than the earlier version (though it did not solve the connectivity issues as I hoped it would be ;-( )
in the mean time you can prob disable selectively the messages by switching the binding to less verbose messages e.g. log.set WARN org.openhab.binding.philipsair
