 A custom setpoint creates the same temporary manual override for every member zone and normally expires at that zone's next schedule boundary. Returns a group control/result object including updated members/state.
 
-Group `power` is a scoped bulk-power/control action. `power=false` immediately powers member units off and releases `group:*` ownership; members are stored as individually-off thermostats rather than being blocked by membership in an OFF group, so a user can turn a thermostat back on independently. `power=true` clears that scoped thermostat-OFF state and immediately re-runs group thermostat arbitration. Explicit Web/Home Assistant group power actions take over older member manual/temporary ownership; scheduled group automations still respect higher-priority manual/local ownership. Group mode/preset/setpoint changes are accepted only while the group is ON. Whole-house power remains independent and authoritative.
