Had none of the set up issues that some users have had (see iTunes WeMo App). Set up was easy and straight out of the box. Created a IFTTT.com account and now I get a free text to my mobile each time the motion sensor is activated. A great product and look forward to more of this from the Belkin range
Week everything worked perfectly. After the upgrade, all of the devices are not available. I tried to set up for two days. Follow the instructions to configure. No device was unable to reconnect to my home network. All returned.
