getDevicePowerState error: 511

[GeRiY]

Hey,

I love this tool :) I used to work with it.
I got { error: 511, msg: undefined } response when I called getDevicePowerState with deviceid.
Someone can explain me why I got this?
Can I see somewhere what is error codes and thier reasons?

Also I have zigbee devices, can I handle it with Ewelink API?
I would to emit a "pressed" event on zigbee switch, I couldn't find the solution for that.

Thanks for reads and helps.

Regards
Geri
