I wanted to see if I could tap of 5v from an aqara zigbee rocker to power a neabry Amazon Fire HD8 smart home display.
- The first is the AC section/power-supply that is wired into the back box - be warned it is quite large and my back box was quite cramped too, it was a very tight squeeze for the installer.
- The second is the DC zigbee section
I asume when comparing across the different (neutral vs no-neutral) that the front portion is quite similar.
Removeing the four screws in the grey portion dose NOT allow it to pop out easily. I had to then reclip it to the back box and pull on the white housing to reveal the circuit board:
Seems to use the JN1589 Zigbee chip
Unscrewing the board and fliping it does not reveal any well labelled points:
Note there is space for 2 more switches unsoldered. I wager that they use the same board for the 3 gang switches, and maybe even the 2 gang switches.
Board number: A20-WSK03-LNS-DC
If I had 8 small bread board wires I could probably connect the two portions and look at the signals and find a 5v rail. But not even knowing which pin(s) is ground means it would be a hard job.
