Niko Home Control for traditional wiring - Why does my connected socket LED keep on blinking blue for several minutes after I’ve successfully added this device to my Zigbee network?
A newly added connected socket to a NHC system will automatically perform a firmware update.
The previous firmware versions of the connected socket show a blinking blue LED during this firmware update.
The newest connected socket firmware does not show this upgrade state anymore and remains fully operational during the upgrade.
For that reason, the information about this blue blinking LED has been removed from the user manual as well.
