how is it possible to get the current state of all wanted hue elements (in my situation, there are only hue light bulbs) and store these information in a cache?
get the status should be the
msg.payload = any right? but how can i save these values to restore it later again?
i'm a voluntary firefighter and i did my pager a bit smart - the charger has a relay output. as soon as the pager is in the charger and trips, the relay output closes and starts an automation like (at night) turning on lights (red, 30% brightness) and turning them off after 30s for example.
now i want that the old values (which got cached) will be restored again after the light got switched off (because i had left the house ). how will this be possible?
