I just bought 6 plugs from HD. The first two were the older version. They configured and connected to Wi-Fi
Then I realized there were new and old versions. The other 4 were the new. I was able to connect via Bluetooth but they never connect to Wi-Fi. I have new and old in the same outlet. The new is always slow flashing blue. The old works great.
Interestingly the app is happy to toggle the power on the new plugs, but of course nothing happens. The app also shows network connection status for the new plug. Yet the plug has slow blue flashing light.
