Wiz smart RGB bulbs have this feature that turns any regular switch into a smart switch. Basically, each time you flick the wall switch on-off the smart bulb cycles through to the next saved preset, wrapping around to the first preset once it gets to the last. If you wait long enough it starts over from the first preset. I realise at the moment flicking the switch 5 times caues Tapo bulbs to restore factory settings, but maybe this could be limited to the first 4 presets. You could think of this as an advanced default state. Thanks!
