I have the honeywell 9000 with remote sensors. While getting the internet connectivity was a little odd (you need this weird redlink device to bridge the devices for web management) They work and are remotely managed extremely easily. They're not 'machine learning' thermostats, but they work predictably, reliably well. Cheaper than a nest, too..
