Thessa is a beautiful and incredibly easy to use widget that allows you to control your Nest Learning Thermostat™, right from Notification Center in Mac OS X Yosemite. Simply click or drag the slider to change the temperature. That's all there is to it!
Additionally, Thessa can receive messages from your Nest Protect™, so you will instantly know when smoke or carbon monoxide has been detected.
Control the temperature in your vicinity right from your iMac or even on the go from your MacBook.
- Set the target temperature for your thermostat.
- See the current temperature and humidity as measured by the thermostat.
- Set states like Home, Away, Heat and Cool.
- Receive notifications from your smoke and carbon monoxide alarm.
- Supports both Celsius and Fahrenheit.

Can’t end Away setting
When the Nest goes into AWAY, the controls on Thessa to end Away don’t work. I have to use another app, Climate, to end Away. Please fix!
Just installed… but so far it works great
Was concerned at first after reading comments on version 1.0… but I took a chance and it works well. It now supports multiple thermostats. Easy to switch between them in the widget. Super easy to setup. Will check back later after I hook up my Nest Protect to comment on its functionality with Thessa.
Developer not maintaining app anymore. Do not purchase.
Partially because of MacOS updates, and partially because of Nest's acquisition, this application is no longer maintained. I used it happily for a while before all development was pretty much dropped. If you purchase this app now, you're just going to be disappointed and donating to an undeveloped, non-working application. You’ve been warned.
With Family Sharing set up, up to six family members can use this app.
