The following scenarios are ideas for possible implementations using suitable hardware. They illustrate relationships, rather than claiming to describe completed customer projects.
01 / The washing machine speaks up. Politely.
A suitably integrated appliance can report the end of its programme directly, for example through Miele or Home Connect. Alternatively, suitable measuring equipment can be used to assess power consumption. Instead of endless beeping, a message appears on the dashboard. If visitors are over, a subtle lighting notification waits until later. Sadly, the laundry still does not hang itself out.
02 / Movie night knows about the doorbell.
A scene dims the lights and closes suitable blinds. When the doorbell rings, compatible playback pauses and a subtle notification appears. The scene can then be resumed deliberately.
03 / The night light knows the time.
A late-night trip into the hallway gets a gentle path of light. During the day, brightness also informs the decision. A manually selected scene takes priority, so every trip to the fridge does not turn into a light show.
04 / The letterbox gets chatty.
A suitable contact detects an opening. A notification appears on the display once someone is home. An opening does not prove that new post has arrived; recognising those limits is part of the planning.
05 / The robot vacuum shows some consideration.
A supported robot vacuum, such as a suitable Roborock model, starts only within the agreed time window, when suitable presence signals and the pet area allow it. Meeting mode or a manual switch suspends the routine. Comfort comes from handling the exceptions, as well as issuing the start command.
06 / ART–SMART: give a picture another dimension.
A lighting installation changes its mood to suit the selected room scene. A deliberately activated party mode can connect colours and music where the devices support it. Everyday scenes stay calm. Art can be smart without turning the living room into a server rack with a disco ball.
First the idea. Then the reality check.
We check triggers, conditions, device connections, manual overrides and behaviour during failures. Critical protective functions remain the job of suitable dedicated systems. Home Assistant can complement them, but does not replace a legally required safety system.
The question is not how many rules we can create. It is which ones actually take work off your hands.
