The state shown for LED components and what happens on the device appears to be inverted. "Feeds" page also shows LEDb with a value of 0 (and LED is 1). Is this intended?
Data in the packet when moving the switch to "On" is:
D [0x44], 2 [0x32], [0x12], [0x01], 1 [0x31]
which seems to confirm that a value of 1 is being received by the device, yet the LED goes out.
When moving to "Off" the packet as expected contains:
D [0x44], 2 [0x32], [0x12], [0x01], 0 [0x30]
but the LED turns on.
