I believe I did say that several days ago, that you must _not_ bridge the LWT topic but should have one node connected to the central broker so that LWT will work. It can just be an MQTT Out with nothing ever sent to it. Put a comment with it on the flow explaining why it is there or at some point you will delete it because it obviously isn't doing anything. Not that I would ever do anything like that of course, said he, blushing.

I am sorry Colin.

Alas I can't control when the brain accepts information and when it doesn't.

Alas other things have happened and I can't do _final testing_ to confirm this is the solution.  
Though it probably will be.

And in 3 days I am going away for 2 weeks so there won't be much going on with it then.

If only I could keep the compartmentalised thoughts ..... compartmentalised.  
(And life to not interfere with things)

But I guess it is all part of the deal.
