timetemp

timetemp

Raspberry Pi-powered time and temperature in custom, 3D printed display. With cloud logging.

IMPORTANT: The Raspberry Pi code has been superceded by the follow-on project:

• idcrook/timetemp3: Monitor and display time/temp with RasPi and log to cloud, 2020 refresh

The website with live charts is still found in this repo (in gh-pages branch).

---

• This project originally launched in 2013.
• It includes a sensor that measures indoor temperature and air pressure. It also connects to online APIs to get thermostat readings and outdoor temperatures.
• It's still in use today.

UPDATED (2020-May-17):

• Switch API for outdoor temperature and conditions

UPDATED (2018-Jun-09):

• Cleanup and ported to Python 3
• Created an updated library idcrook/python3-phant
• See BUILD_PYTHON3.md

Wiring Diagrams

• Fritzing source file (Fritzing app)

Hardware References

• 2 of Adafruit 1.2" 4-Digit 7-Segment Display w/I2C Backpack, with custom designed 3D printed case
• Adafruit BMP085 sensor breakout board (Discontinued)
• Adafruit I2C Level converter
• Raspberry Pi Model 2 B
  • PSU and Ethernet networking, running Raspbian
• Seeedstudio Breakout Kit for Raspberry Pi B w/40pin to 26pin Cable (Discontinued)
• Solderless Breadboard, wires, and a shelve
• Raspberry Pi Model B (1st gen.)
• Pi Cobbler Breakout + Cable for Raspberry Pi

My scripts

Way back in 2013, used Adafruit python libraries on this Pi when this project was created, on my first ever Raspberry Pi.

Updated in October 2016 to use more recent library versions and overhauled in 2018 to additionally use Nest API (thermostat temperature), Dark Sky API (local outdoor weather), and swap in some other hardware.

• "Time", displays current local time (relies on NTP to sync Internet time)
  • my_7segment_clock.py
• "Temp", reads BMP085 sensor, displays on LED display. Logs to a stream at my own phant server
  • weather_logging_phant3.py
  • .json files to hold configuration settings (like phant stream and API keys)

Updates

(2018-Jun-03):

• Updated to work with latest (version 4.0.1) python-nest module

(2018-Apr-19):

• Added Dark Sky and Nest API support for displaying outdoor and other indoor temperatures.

(2018-Mar-25):

• Added most recent code and explicit dependencies as git submodules. See Build.md

(2016-Nov-05):

• Added pointer to Porting indoor weather (BMP085) logging project to SFE Phant blog entry.
