Writing a script to control one of their thermostats does not seem like a difficult task. I would do it but I do not have such a thermostat to test with and that is always the rub. It would be trivial if the pronto had a Web browser but it does not. All data will have to be gotten through HTTP GET, but there are a finite number of screens and they will not change in format so page scraping is a definite possibility. It would be nice if they had some sort of XML mode but the one I looked at the Net10e did not.
