homekit devices are saying unresponsive

Having this issue with all my devices. A mix of Meross light switches, Meross Smart plugs, My EcoBee etc.

All of them are saying the same thing.

On the EcoBee the app on my IOS device is working just fine, and Same goes for the Meross devices I can use them all in the Native app but home HomeKit any more.

I am running a unified network and everything has worked fine till the last couple of updates all devices are showing a 95%-100% WIFI connectivity so it isn't the network.

Using a HomePod and that was also not responding till I rebooted it, but even after the reboot nothing is working in HomeKit.

I have tried HomeKit on my Mac's, iPhone,Ipad etc all say the same thing.

Every now and then a Smart plug will show working and it will for a bit and then stop, but again it works with in the Native app.

Thought?
