HomeKit - Accessory out of Compliance

FYI — I started with one light, it went well.
Then more and more until it finally fell over with 33 devices. Got messages telling me hub was overloaded. ( I have 2 hubs networked together )
I did remove apps and anything I could think of to lower load on hub. After a reset or two and apps removed, I’ve not seen the overload situation again.

So i started to reconnect HomeKit. I decided this time to just adding contact switches and water sensors — about half ). Tried resetting the QR code, and finally figured out that I also had to “unpair all controllers”. That got it to where it would start to reconnect. It scans QR code ok, but then I started getting the dreaded “accessory out of compliance”.

Since then, I’ve not been able to get it to where it will allow me to re-add the bridge to HomeKit.

Any thoughts?
