I have an issue with my Echo Plus, in my region is common the power cuts off, specially in rainy season.
After a power cuts event, Alexa starts OK, however, power on all my bulbs.
Is there any available solution for this issue?. Can my bulbs starts to the last states before power cut off event or start on off states?, Can Alexa notify us that a uncommon event occurred (all lights on at the same time)
Note: I have a mix of bulbs (Sengled and Phillips)
If I switch a hue bulb off and switch it on again it comes on, which seems to be the sensible response from the bulb as it has no idea if it was on or off when the power is restored -other than its last colour state (did that make sense?)
i do not know if that is the case if the power is lost to the Hue hub at the same time.
there may be something in IFTT that will address the problem if power is lost, or indeed from within the Hue app (and other bulb app(s))
thank you for bringing this up as I had never considered such a scenario, all my lights go off at a certain time so it is not a long term problem for me (lights staying on for days), but I have other things that will need attention.
i guess a workaround is setting up a Alexa voice routine to switch everything off for when it happens during the day, or night e.g. “alexa all off”
edit: hue bulbs are always “on” all the time (in a table lamp the lamp is plugged in and switched on) and only change state when wirelessly or power instructed to do so, which a power off/power on would initiate. If memory serves, this is explained in the bumpf with the bulbs.
to use a hue bulb with a smart switch would involve initiating the switch to activate the bulb and then initiate a command telling the bulb what you want it to do (change colour, switch off)
i am intrigued as to how it can tell the difference between a voluntary or involuntary power change.
It can't. Philips implemented a 'default power-on state' feature, doesn't matter what caused the power-on state, an outage or user flicking a switch. IME most smart bulbs behave as luzume describes. I have some IKEA drivers and bulbs, they do the same.
So you have this disadvantage that if you get a power cut all your lights come on. An advantage is the bulbs (almost) behave as expected for people who still insist on using the switches, rather than them walking into a dark room, togging a light switch several times and being left in the dark.
