Issac KellyWeMo API Hacking
WeMo Hacking part two!
In short! It works! miranda, with some tweaks and fixes is a good tool for tinkering with your Belkin WeMo switch with Python. I'd suggest starting with my toolkit here: https://github.com/issackelly/wemo
The WeMo is communicating over pretty standard UPnP, though like anything else, it has some quirks.
It wanted a very specific namespace string for the SOAP envelope that contained a trailing slash and Miranda wasn't sending that.
I also added the same User-Agent that the mobile app uses for the HTTP (via UDP for UPnP) headers, and fixed the character encoding, and used consistent namespacing with the mobile app.
If you poke at Miranda you'll see that you should be able to figure out how to set schedules, and settings pragmatically through the SOAP interface, it's all there.
A simple session would go like this:
rivendell:~/P/p/wemo [master]
$ ./miranda.py
upnp> msearch

If you want to use my utility on top of miranda, it should work for you. No promises Get it from github: https://github.com/issackelly/wemo/zipball/master
Open a shell and locate the wemo directory
$ cd ~/Downloads/
$ unzip issackelly-wemo-1afe45d.zip
$ cd wemo
$ python
>>> from wemo import on, off, get
>>> on()
True
>>> get()
True
>>> off()
True
>>> get()
False
Read through wemo.py to get a better understanding of scripting miranda. (again, start with my miranda.py, as it's tailored to the WeMo)
