Sonos ZP100 and ZP80 unknown to Sonos binding

Add-ons Bindings

I recently discovered the following text on one of my players;

Sonos ZP100

Zone Player

The Zone Player represents a Sonos Zone Player which is not known to this binding

Then I looked on others and also found

Sonos ZP80

Zone Player

The Zone Player represents a Sonos Zone Player which is not known to this binding

Is this because of the binding actually does not know these players, or is this because it was a very long time ago since I added the Sonoses to my OH system?
I’m now on 2.1.

I’m guessing this is a binding issue, since my Play:5’s are recognized, and I sometimes get Line-in exceptions in the log.

Try to remove them and then add them again.

OK, so I tried on one unit, and it made no difference. Or did you mean that I should remove all of the unidentified units before re-adding them?
