Amazon offers the WeMo Maker Controller for $65.04$65.63 with free shipping. That's the lowest price we could find by $18. It allows you to control select low-voltage electronics remotely via your smartphone.
I wouldn't give 2¢ for anything Wemo. The Wemo smart plugs I bought worked ok until the first firmware update. It has been downhill since then. I replaced them with TP Link smart plugs which work flawlessly.
The fact that this doesn't work with the Amazon Echo makes this even less appealing.
