Following these two links, I created a new group called “family” a put my dad on that group, so that he can only manage (turn on/off) some entities when he comes home when we are away:
Hi Marco, I’ve recently started setting up something alike, but I faced different problems.
Did you edit this user using the UI after adding the new group on the auth file? I made a few tests and noticed after rebooting my manually added group config is still there, but if I change anything using HA UI, all the params for the user are overwritten.
You have to stop homeassistant to modify this file. I connect my instance to ssh, and write ha core stop. Modify the file and save. Thern ha core start and works. Regards
