TIAO Smart Sprinkler Pi

For system connection diagram, please refer to TIAO Smart Sprinkler Pi System Connection Diagram.

The TIAO Smart Sprinkler Pi (TSSPi) is a piece of hardware controls your irrigation systems. It replaces your traditional sprinkler controller. TSSPi has many benefits over the traditional sprinkler controller:

  • Web interface - program the watering schedule using your PC or mobile phone
  • Supports complicate watering schedules
  • Unlimited watering schedules
  • Allow seasonal adjustments
  • Weather API access - automatically adjust watering amount/time by checking online weather forecast (rain/wind etc)
  • Control your sprinkler stations from anywhere in the world
  • Software supports unlimited stations
  • Total of 16 stations (or 1 master station + 15 stations), can expend to unlimited stations using our extension board
  • Software supports unlimited stations
  • Supports rain sensor
  • Open source software - which means you can add your own function to the controller!
  • System ON/OFF hardware switch
  • Status LEDs (power, Pi power, system on, system running)
  • Low cost! It's cheaper than the traditional sprinkler controller!
  • Supports Raspberry Pi 1 Model B (version 1 of TSSPi)
  • Supports Raspberry Pi 1 Model B, Raspberry Pi 1 Model B+, Raspberry Pi 2 Model B, Raspberry Pi 3 Model B, Raspberry Pi Zero (version 2 of TSSPi)

TSSPi Hardware Dimensions

Version 1

The board dimension of TSSPi is 122.5 x 87mm, or 48.2 x 34.2 inch. It also has 4 mounting holes, the radius of the mounting hole is 2mm:
