Zigbee allows me to program off and on independently, so landing light outer set to switch off at 1 am, and inner at 2 am, so even if we as
forget, the lights still switch off, it also means when I have made two cups of coffee so hands full, when I realise at bottom of stairs the landing lights are off, saying hey google turn on landing lights turns them on without me needing to put down the coffee's to manually do it.
OK 5 x 6 watt for all landing lights, 4 x 6 watt for outer, and 1 x 2 - 6 watt for inner depending on how the smart bulb has been set, normally set to "Gorgeous" so around 2 watt, it looks pretty, changing between all the colours,
maybe not practical, but what the heck, it's 2 watt. And enough to see my way to the loo.
A PIR
can turn lights on/off, I however use some thing like this
it also means with a power cut, can still see way down the stairs. And it auto switches on as we pass it.
Even at 70 plus I can say "hey google turn on landing lights" and "hey google turn off landing lights" the problem is when the grand children visit and they say "hey google set alarm for 2 am" before they leave.
