Describe the bug

Problem #12 (comment) still exists on Lanbons and current CC versions:

• turn on moodlight from HA entity (the one created by this component)
• select a nice color and brightnesd, and test by turning the moodlight on and off repeatedly from HA - everything's fine at this point
• turn the moodlight OFF
• restart HA and reboot or power-cycle plate in the same time
• try turning on moodlight: color/brightness forgotten + error below

The real world case is very simple: a power outage can restart plates and HA in the same time.

Can be reproduced also by sequential restarts:

• turn moodlight on, select a color
• turn moodlight off
• restart plate, wait for it to boot
• restart HA, wait to finish and sync with the plate
• turn moodlight on.: color is lost

hope it's fixed ;)
