This app is the answer to WEMO and Hue devices working together! – MasterSwitch for HomeKit+Hue Review

Best solution I have found for controlling WEMO plugs with Phillips Hue bulbs! The app detected all devices and connected to the Phillips Hue bridge immediately, automatically, and with no issues encountered. Setting up the buttons had a learning curve, but only because the there are so many customization options. This app and developer succeeds where Belkin and the WEMO app fail.
