Wemo Motion - Alternatives for 1.8?

I’ve been persevering with wemo motion + IFTTT for a while now. I recently moved the wemo motion to a space with an RF lightswitch. When the motion was just to detect an entry-way it was ok, but now that I have an action attached to it, the IFTTT integration takes about 10 seconds for motion to light-on - which is a very long time to be standing there.

Anyone figured out any creative alternatives for Wemo Motion using 1.8? I had a look at ouimeaux, but I’m not sure if I want - yet another service - started on my poor little Pi.
