Input msg.payload on node

[mcponta]

Hello biddster!!!
Thanks for your great work.
I have been using node-red-contrib-wemo-emulator for a long time, but now I want to ask you, of course, if it is possible to add an input, like msg.payload, to be able to send an external command to both turn on and turn off the node. Why? I have a rasp and a Siemens LOGO controlling my home automation and for example, if I ask Alexa to turn on a device, it turns on an output of the Siemens LOGO, but if I turn off this output directly through the Siemens LOGO to Alexa, the device is still on, do you understand?

Please, forgive my English mistakes and a big hug from Brazil
