If you switch power to a light or wall socket this should only be implemented with a bistable relais. Use the monostable relais actuators for your window blinds/shutters. Shutters/blinds actuators only turn on the relais when they are moving, this is what I meant with “a short time”, so it’s OK to have a monostable relais here.
Universal actuators (that can be used in switching or shutter mode) have bistable releais (or should have at least).
