Termo-API

A Go based API for a DIY internet controlled thermostat.

Hardware

- Raspberry Pi (Model B) - Sainsmart 4 Relay Module - DS18B20 Temperature Sensor

Dependencies

• Go
• gin a Go web framework.
• hwio a Go GPIO library.
• Termo-UI is an EmberJS powered UI for this API.

Building (on OS X 10.9.5)

• Download and mount the arm5 crosscompile toolchain
• $ script/build_for_pi

Note: The toolchain is only needed if there is a cgo dependency.

Deploying

• Create ./api_key see ./api_key.example
• Edit script/deploy variables as needed
• $ script/deploy

Note: Currently termo-api is deployed as root so as to interface with GPIO pins, this is awful, and will be remedied soon.

Starting

$ API_KEY=foo ./termo-api

Issues

• Permissions issues are preventing running the server as a non superuser
• Hardware build needs to be documented.
• No unit tests
