Support for multiple power points on the same board.

[Just-another-pleb]

I bought a power board which has 3 power points.

It has been reflashed to SONOFF-TASMOTA software.

I can control all three with function nodes and MQTT nodes.
But it lacks the feedback to show the state of each output.

No big.

I was told that the original SONOFF stuff only support 1 output.
But it would be nice if you could modify the node so it does.
