Trigger works when ZigBee All On is sent #2

Closed exsilium closed 6 years ago

exsilium commented 7 years ago

When testing OSRAM Lightify ZigBee 4-button switch, which by default has a function to send out "All On" / "All Off" command it was seen that the Trigger also reacted to the On command. As the aim of the trigger is to control gates etc. This should not happen. Ignore broadcast commands and only Trigger when signal is explicitly sent to the device.

Some findings:

The Lightify ZigBee switch sends the ZCL Frame Control as 0001 0001 using the upper part of the frame control which should be reserved?
It's possible to detect the broadcast signal via envelope->options. The switch broadcast option is sent as 0x301 (0b1100000001)
