Controlling a hot tub

I have been hooking up quite a few thermostats for clinets so they can warm their ski cabins before arrival.

I now have one that want to have some control over his hot tub.

Any suggestions?

Been researching this and found someone else was able to do it using Homeseer . So should ther not most likely be a way to use Vera?
