How can I stop my Philips Hue bulbs resetting to full brightness after a power cut?

Question

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.

Answer 1

@Helmar 's comment is quite good for a workaraound : You should monitor power outage.

Monitoring power outage is starting to become recurrent here and it is critical to see if there was an intrusion attempt. So several solutions can be managed to detect power recovery:

• ping your Internet gateway and log the last time you did this. If the time is large (> 1 minute), you just recovered.
• query an UPS connected to a RPi or any computer to see when the battery is loading
• ...

You could then issue a command to reset the previous light dim stored in a global variable.

Of course a Philips Hue oriented answer could be interesting but automtated light bulbs act funny during OTA updates or rogue rules so you might not have the behavior you want.
