Just wondering what is going on... Does anyone have any ideas? how to fix this?

I might have jumped the gun on this since I restarted HA and restarted MTTQ and even upgraded MTTQ but nothing works... Integration to the inverter is stuck

This is normal:

It is the Supervisor heartbeat regularly checking that the broker is running. Nothing to do with your issue.

You should start by telling us which integration you are using. Also check your core logs.

Tom, thanks for the tip... I was stuck on something being wrong with mttq... I am using sunsynk/deye inverter and now i looked at the logs for that - i noticed that critical fault in there - can't connect to the dongle ip.

I verified from the router - the dongle IP has changed after about 3 years that I have been running this... I have to look into that now but when I corrected the new IP - everything started to work again.

Comment: Can I suggest allocating Static IP Addresses in the DHCP section of your router configuration for your devices to prevent this scenario recurring?
