Hey there,
I’m using homegear with homematic-binding instead of MAXCUL, so I’m not aware of issues with that.
You can read the reasons for changing the behavior of requesting the credit report here.
I think, it’s no good idea to request a credit report after every arbitrary command.
Back then I thought about a request, called from MAXUL, to explicitly get the credit report or just send a command and handle “credit errors”.
Unfortunately (or luckily), due to a new job, I haven’t had enough time to look into this back then.
Cheers
Mik
