Allow/block IP or MAC addresses for individual switches?

Is it possible to configure a switch (or any other item) to only be controlled from specific IP addresses? It’s like giving access permissions to certain users and blocking others.

eg. The master bedroom light cannot be turned on/off by the child’s phone but, only by the parents’ phone.

Didn’t try it out myself yet, but you may have a look at the new multi user feature introduced with v0.74:

Cool, thank you. I read that the devs want to make HA available for office environments with multiple users so, there needs to be permission restrictions implemented. I didn’t know if it was ready or not.
