We have covered a bunch of connected air conditioners here in the past. The Ambi Climate happens to be a handy device that turns your dumb air conditioner smart. The device lets you sync your air conditioner to your iOS/Android smartphone. It uses its sensors to monitor the temperature and environment inside and outside to make decisions. It can automatically control the temperature and save you money. You can also use the Away mode to keep your home at a certain temperature / humidity level.
The Ambi Climate is easy to install and location aware (thanks to your smartphone). The companion app provides you with useful information about your energy consumption. You can get one of these on Kickstarter.
