Wifi smart plugs
I don't know if anyone else has tried these but I recently obtained a couple of wifi smart plugs from amazon:

There are quite a few around using various brand names and based on the ESP8266 wifi chip I think. While the RF plugs that I use are generally pretty reliable these give another option and it would seem could be integrated with the HAH using python code from here:

I've just used a lua app to send data to my raspberry pi which is on the network anyway running the fauxmo.py script for amazon echo integration. There's a bit of an issue regarding having the app open on your phone because the devices can only have one connection at a time but it seems to work on an experimental basis so far.
Just something else which could help to keep this excellent system alive.
Allan I have just purchased a wifi smart plug and am quite impressed with its speed to respond "Alexa" commands.
I wish I had the skills to write the software for the Home Automation Hub and incorporate/integrate these devices into the HAH platform.
