So three more power cuts over last night. Each one lasting several minutes. At the end of each one,
all my Hue bulbs/devices (strips & plugs) were turned on and with all colour reset. ie: Every single bulb and strip was (reset) to a warm white colour.
So over the course of about 7 power cuts in the last 24hrs, 6 left all my Hue devices on/reset. And just one time, the Hue bulbs/unit were left set to the previous setting (which is obviously what I have them set to do).
It's ridiculous that a power cut leaves every Hue unit turned on/reset
