@David-Coulson, I'll look into it.
One thing you can check in the meantime make sure this checkbox is unchecked in your profile:

Can you show me one of the emails? I wonder if it's reminding you to subscribe because you're running more than 1 command per minute. I'll add an option to disable those emails too.
Also, did you enable "Home Assistant Offline Configuration"?
