I've recently been having issues with lights not updating or responding until I run the HassBridge configure option again. I noticed in the 2021.6.3 release notes, there is an update regarding MQTT lights:

I'm not sure if it's an issue with the plugin, or my setup, but I never really had problems before. I would have to run configure for the HassBridge plugin when Indigo would first load, but other than that I never had an issue. Now it seems I'm having to run it randomly when the lights or other HassBridge devices get out of sync,.
