Updating other components states

Development
1

Is it possible to update other entities states.
The case I’m looking at is:

I have a component to manage my blinds (see yaml). The commands are RF commands, so I prefer to just send 1 for each task, not group them together which would result in multiple commands.

Edit: Based on some research track_state_changes seems like a good option. This is where I’m up to:

covers:
    blockout_blinds:
      friendly_name: blockout
      command_stop: ...
      command_open: ...
      command_close: ...
    sunshade_blinds:
      friendly_name: sunshade
      command_stop: ...
      command_open: ...
      command_close: ...
    all_blinds:
      friendly_name: all
      command_stop: ...
      command_open: ...
      command_close: ...

What I want to configure is when all_blinds does a command it updates the state of sunshade and blockout, ideally configurable like:

blockout_blinds:
      friendly_name: all
      command_stop: ...
      command_open: ...
      command_close: ...
      covers_list:
        - cover.all_blinds

Component snippet

track_state_change(hass, self._covers_watch, self.covers_state_changed)

For anyone who’s looking this up, this is how I achieved it:

from homeassistant.helpers.event import track_state_change
...
track_state_change(hass, self._covers_list, self.covers_state_changed)
...
def covers_state_changed(self, entity_id, from_state, to_state):
      try:
          _LOGGER.debug(entity_id + " change from " + str(from_state) + " to " + str(to_state))
          if to_state.attributes.get(ATTR_CURRENT_POSITION) != self.tc.current_position():
              _LOGGER.debug(self.entity_id + ' changed position from ' + str(self.tc.current_position()) + ' to ' + str(to_state.attributes.get(ATTR_CURRENT_POSITION)))
              self.tc.set_position(to_state.attributes.get(ATTR_CURRENT_POSITION))
              self.schedule_update_ha_state()
      except:
          pass
