And we have another friend.

I got through adding my RM4 Pro through the new integration, but no entities/devices were created. I'm hoping this will fix the problem as I've got nothing right now. Log error below:

Yes, this will fix.

We’ve had a number of releases and this hasn’t made it in yet? I’ve lost support for half my home automation as a result.

I opened the PR in the first hour. Not sure what else you want from me.

Use the remote for now, it's not the end of the world 🤣
