Wow - I've just set up Amazon Echo; logged into the Echo Honeywell account; I asked it to discover devices; it discovered all 12 zones; I asked Alexa to set the temperature in the Living Room to 23 degrees. ALEXA DID IT!

It only too 5 to 10 minutes with no hiccoughs.

What more can I say? Clever Amazon and clever Honeywell!

And here is the proof:

I wonder what other Evohome commands it will accept?

Time for a glass of red wine in my 23 degree living room to celebrate I think.
