OJ Electronics Wireless Thermostat

I have radiant floor heating in the bathrooms of a short term rental house and would like to be able to control them when guests are not staying. I already do this with a google calendar plug-in, PLEG, and a 2gig CT100 for central heat.

Has anyone tried to use the OJ Electronics WiFi thermostat with Vera? LINK

EDIT: I just found this one too, anyone used it? Stelpro KI LINK
