I ran the command, to uninstall "node-red-contrib-harmony-websocket" and it has stopped the messages???!!! (@realjax - I shouldn’t have doubted you, and just tried it )
I can now add/move/change nodes and do deployments with no server update message (so far)
I wonder what the hell that Harmony add-on was doing and why do I not see it elsewhere I have it. (I’d still like to get the root cause as I’d still like to use that add-on)
