Hello!
A new development for the Tuya integration is underway and will eventually allow you to add additional devices such as your charger.
Unfortunately, I can’t give you a date or deadline, just tell you that it’s coming.
I’m tagging @Terdious who had a hand in this so that this message doesn’t get forgotten.
If you want, the discussion thread is here:
