That's a good question - and I'm not sure. I created my app when I had a Nest thermostat and was working from home. The thermostat would assume that no-one was at home during the day - and so turn off the heating - as I didn't walk past it often enough, so the original purpose of the app was just to detect when I was actively using my PC, and ping the thermostat not to go into "Away" mode. It was then really rewarding to add more features and make the app available for others to use. I got some lovely feedback and sensible feature requests via email, and one user generously did a French translation of the UI. I even got a small number of $€£s in Paypal donations! However. I no longer have a Nest thermostat (moved to Australia, where they're not available), no longer work from home, and now have a young son. So I have to admit that prioritising the time & finding the motivation to rework the app to work against a different set of APIs (if even possible) may be hard to come by.
