Using the Ohmie smart HVAC action, Google can now help you to interact with your Symbiot and other smart HVAC devices using intuitive voice commands. Voice commands are directed at zones within your property. These zones will correspond to fan coils, underfloor heating zones or pool heaters. The mode of fan coils and underfloor heating zones can be set to heating or cooling. All types of devices can be commanded to turn on/off and set their target temperature (restricted to 16 - 30 degrees Celsius for fan coils and underfloor heating, and 18 - 30 degrees Celsius for pool heaters). All devices can also be queried for their states.
