Function by sending two triggers to the device. This presents a problem when using wemo devices to toggle devices which affect the network.
A very strong use case for a wemo outlet is to restart a router if network connection is lost, or upon getting a request by any ifttt trigger. This small change could enable those situations to function. Currently, a "off then on" instruction to a wemo outlet powering a router will just shut it down, never to start again.
Tldr; iftt "off then on" and "on then off" instructions should not require two separate network requests.
