Dual and 4 channel models should enumerate multiple wemos
I have a Sonoff Dual and an Amazon Echo. When I Discover devices in the Echo app, it shows only one WeMo switch, but would be nice if it shows up as two. The 4 channel model would likely discover 4 devices. It would likely be cleaner if Belkin WeMo had multiple channel devices. I am going to try sending multiple UDP packets in wemo_respondToMSearch(), while incrementing the serial/uuid. The functions in webserver will also need some work.
Don't know if this really works. Depends on how flexible the Echo is with accepting different UDP answers AND using differen setup.xml files. You would also need a friendly name per device. Currently I use the MQTT device name. For multi device support there should be a friendly name per device changeable by MQTT and stored in SPIFFS. A probably cleaner approach would be a HUE-Bridge emulation but that is much more complex than Wemo emulation.
Here is an Implementation of multiple WeMo Devices on one ESP8266: https://github.com/kakopappa/arduino-esp8266-alexa-multiple-wemo-switch
It's rather simple by design but requires a webserver for each emulated wemo device. Not the way I'd prefer.

Until WeMo updates the API, an extra port per extra channel may be necessary. Those additional webservers could be limited to the 3 (I think) URLs specific to the WeMo interface. I'll give it a go when I get more free time.
I've got an ugly hack that needs refactoring, but a second device shows up. I'll clean it up when I get back to it.

I'm looking into a HUE Bridg emulation version for 3 Reasons:
- Only one webserver
- Would allow for Dimming (should this ever come in a Sonoff-Device)
- RGB-LED Support
But Hue-Emu ist more complicated. Need to find out how Echo exactly detects the Hue Bridge and how it does access the devices. Hopefully there is just a minimum api setup necessary.
Greetings, Heiko.
Ok, UPnP part seems to work now, Echo requests description.xml and then tries to get the configured lights. Will continue work on http part then.
Success on HTTP part. Echo now registers a Hue smart home device emulated by the sonoff. The detection process is now understood. Now it's time to implement the required API functions...
Basic Hue emulation now working. Switching on/off devices now works and every channel is listed as own device on virtual HUE bridge.
Hi Don,
I used your code to provide a HUE Emulation mode with 4 different friendly names. So we now have a multi channel solution without different webservers and completely different names per channel. You may try my repository if you want to try it.
