Background

The Nest thermostat has provided all sorts of revealing details about our AC and Heating.

My curiosity kicked in to see what else could I learn that the Nest doesn't provide. In doing so, I attempted to answer the following:

• How well does it stay at target temperature?
• How does the outside weather affect this?
• Can pre-cooling help? And at what outside temps?
• How does humidity (indoor and outdoor) play a role?

The Nest already provides a historical view but only answers how many hours it ran.

What this repo does

nest.py does the following:

• Get thermostat data from Nest
• Get local Wunderground data from a PWS
• Merge and timestamp data
• Print metrics (for Datadog to consume via Cloudwatch Logs)
• Store in a Datastore
