According to this comment on Reddit, Philips Hue bulbs reset to 100% brightness after any power interruption (e.g. a power cut, switching the physical light switch off then on, etc).
This does seem like a useful safety feature, but it's not practical for lights in my bedroom; if there's a power outage and then the power comes back on, the lights switch back on at 100% brightness, waking me up again. For areas where the power supply occasionally has problems, this could be a really big problem - imagine being woken up multiple times per night if the power cuts out, even for a couple of seconds!
Is there any way I can prevent Philips Hue bulbs from returning to 100% brightness after a power reset? Official solutions or workarounds would both be helpful.
