Been waiting for something like this, but...

Works well for simply adjusting the temperature, though it doesn’t seem to be able to handle Heat + Cool mode in which you set a range, which is kind of annoying. It also doesn’t seem to be able to switch modes—only adjust the temperature in the current mode. When it’s more full-featured, it might be worth the $2.99. As is, I’d just use the web portal.
