Well, if we take a one off case, say a smart plug behind my desk which I want to turn on/off with a smart button on my desk?
Hue
Given I've already got Hue all I'd need to have is a Hue Button (£18) and a Hue Smart Plug (£22) = £40
And as the Hue Smart plug appears within Alexa Routines, it can be controlled from there (or from Hue) for voice command or schedules etc.
Flic
About £150-200 for the hub and four switches. But that means yet ANOTHER hub. I already have Hue and Blink and Somfy ones.
BUT
I have FOUR Gosund smart plugs already, which I'd like to control with buttons... So Flic would be the only way to do that!
If Only
If only Amazon had Flic like buttons for £30 a pop which worked within the Echo infostructure
Answer?
Looks like the best solution is the Flic one, because at least that gives me four automation buttons which are completely independent and can just fire off Alexa Routines.
Sighs! At expense!
