TIAO Smart Network Sprinkler Controller

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

The TIAO Smart Network Sprinkler Controller (TSS) is a piece of hardware controls your irrigation systems. It replaces your traditional sprinkler controller. TSS 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 (5V and 3.3v power)
  • Status LCD - displays system status etc
  • Low cost! It's cheaper than the traditional sprinkler controller!

TSS Hardware Dimensions

The board dimension of TSS 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:

Toggle between the main controller (MC) and each expansion board (E1, E2, etc). Manually start an existing program or a test program.


LCD display header

Insert the LCD module directly on the LCD header. Make sure pins are aligned, otherwise the LCD/controller will be damaged.


Ethernet receptacle

Plug Ethernet cable here for network access. If wired network is not available, there are many other options, such as using a wireless router in client mode (for example: 150Mbps Wireless N Nano Router (Micro USB Power) TL-WR702N or 150Mbps Wireless N Mini Pocket Router (direct power) TL-WR700N) or powerline network adapter kit (Linxe LSP06 200Mbps etherent powerline network adapter Kit (2)).

Pin Description
PWR ON: VIN (5V) is working
V33 ON: Vcc (3.3V) is working

24V AC and rain sensor header

None

This header allows you to connect the power (24V, 2A AC) to the TSS. This is the only power source needed for the controller. For power, connect one of the 24V AC 2A transformer's terminal to pin 8 (24V AC In) and the other terminal to pin 7 (GND) For rain sensor, connect one of the rain sensor's terminal to pin 5 (Rain sensor terminal) and the other terminal to pin 6. The rain sensor is optional.

Pin Description
1, 2, 3, 4 Common wire, connect to sprinkler valve's common terminals.
5 Rain sensor terminal
6, 7 GND
8 24V AC In

Station 1-16 header

None

TSS can control 16 stations (including master station if you have one) without expansion board. This header has 16 connectors, so you can connect up to 16 valves.

  • Example 1: My irrigation system has 10 stations, I do not have a master station.
    • Connect RED wires of the valves to 'Common wire' connectors (see #24V AC and rain sensor header), then connect BLACK wires of the valves to connector 1 to 10 respectively.
  • Example 2: My irrigation system has 15 stations, I have a master station.
    • Connect RED wires of the valves to 'Common wire' connectors (see #24V AC and rain sensor header), then connect BLACK wire of the the master valve to connector 16, and other BLACK wires of regular valves to connector 1 to 15 respectively.
