Two Devices for one Dimmer.

[McMelloW]

Hi Folks,

This guy, Willem Aandewiel, created a low cost DIY, WiFi Dimmer (DONOFF) controlled by an ESP8266 with his own firmware.
See on Github and on his own website

But I would like to use this Tasmota firmware flashed on it with this hardware. After flash Tasmota and configuring it with the following template.
{"NAME":"Donoff","GPIO":[0,288,160,416,0,0,0,0,0,0,0,0,0,0],"FLAG":0,"BASE":18} Auto Discovery created two devices in Domoticz. A on/off switch and a dimmer switch. Only the on/of switch seems to be connected to the ESP8266. The dimmer switch seems to be connected with nothing.

What makes AD creating 2 devices and only connect 1.
