Cannot handle Sonoff 4CHPROr3 device
I'm trying to configure a Sonoff 4CHPROr3 device.
In the ewelink app, I can add and manage the device without any issue.
As soon as I add the device in ewelink, my homebridge detect the new device but he cannot manage it.
If I reststarted my homebridge ... and can see this message in the logs:
