Getting Systems to Talk
A Cybernetic Feedback Loop
How IFTTT Maps to a Cybernetic Feedback Loop
IFTTT breaks everything down into triggers and actions.
We will think of this through the framework of measure and act.
How IFTTT talks to services.
IFTTT talks to services (i.e. TP-Link Kasa, or Wireless Tag). The service then talks to its hardware products. For example the Wireless Tag service talks to its tag manager and temperature sensors.
Wireless Tag — Temperature Sensors
- Light Sensor 1 — Avery 505
- Light Sensor 2 — Avery 4th Floor Stairwell
- Light Sensor 3 — Ware Lounge
Temperature & Dew Point
Light
1 — Avery 505
The light mimics the pattern of sensor 2 as the sun moves, but is less bright as the sun doesn’t hit the sensor directly.
2 —Avery 4th Floor Stairwell
You’ll notice the sensor in the 4th floor of Avery has drastically greater brightness with direct sunlight in the afternoons. A pattern of from the sun’s movement emerges throughout each day.
3 — Ware Lounge
Ware lounge is relatively dim, and even seems to go dark on Sep 10–12, perhaps a table that was placed in front of the sensor?
