Temperature Sensors Part 2: Grafana

Recording temperature into InfluxDB isn’t very useful if I can’t visualize it. Thanksfully, Grafana exists.

This is part 2 in a series describing my DIY temperature and humidity sensors.

Grafana Setup

I have Grafana running on the same webserver as this website, configured with two different data sources:

1. My InfluxDB server (Currently a Raspberry Pi)
2. The DarkySky.net plugin for an approximate idea of the outside temperature (Plotted as apparentTemperature on the graph below)

Records:

• The recorded temperature in my room was 56.09°F on October 19th at 8 AM. Later that day the heat was turned on
• Since the heat has been turned on:
  • Living room:
    • Max Low: 67°F
    • Max High: 68.34°F
  • My Room:
    • Max Low: 36.65°F
    • Max High: 75.02°F

Takeaways

• My third floor room is colder than the second floor living room directly below by about 5-7°F on average.
• Turning on the living room ceiling fan lowers the living room temperature, but does not change the temperature in my room.

Actual Graphs

Below is a “snapshot” of the data my temperature sensors collected between Oct 22nd and Oct 29th, 2018. To make it load quickly I’ve set the resolution to 30 minutes (each point on this plot is the average of the past 30 minutes).

I’m also collecting relative humidity data:
