Alexa and Harmonic Hub to control "Power Plug Connected"

[ric80]

Hi All,
I liev in Belgium and just got an Alexa (Amazon Echo) + an Harmonic Hub.
I thought the Harmonic HUB would allow me to control my RF power plug but it does not (unless I missed something).
So if it's really the case, what should I buy as a "connected plug" to be able to control it via ALEXA?
I can see that CHACON has some kind of HUB connected to the Wifi and can control several plugs but will it be controlled by ALEXA?
The idea is to have an activity in Harmony HUB which would turn on Power plug, then start al lthe devices correctly to start the TV on HDMI 1, ask the Cable TV decoder to start with a dedicated channel, start the BOSe SOund bar by 1 voice command in Alexa.
Help appreciated
Thanks,
Ric.
