By switching sockets on and off, you cannot smart steer a charging station or heat pump. Smart steering means you can adjust the power to the charging station, not just switch it on or off. Ditto regarding the heat pump, you need to be able to do more than switch it on or off.

By adding extra Qbus modules in the installation, additional savings can be realised - not only by smart control of appliances via socket outlets but also control of lighting, heating, cooling, ventilation, etc.
