I personally use both a smart light bulb and a smart watch. The smart watch is to track my heart rate during running and light bulb for wake up and sleep routine for my 1 year old.
Smart switches can also turn on and off heaters and light bulbs, smart washing machine is very optional but timing it so that it completes when I finish work is nice, some people can time heavy electricity use for night time or peak solar to reduce cost.
None of these need to be smart but there are some benefits for some of them.















I don’t recognise many, but there are a few that pop up regularly like PugJesus, Picard Maneuver and K O L O N A K I.
