1.
Introduction
(OSBee) 3.0 is an open-source, WiFi-enabled sprinkler controller for
latching
solenoid
valves. It is suitable for garden and lawn watering, flower and plant irrigation, hydroponics, and other
types of watering projects. It comes with built-in WiFi, OLED display, laser cut acrylic enclosure, and can
switch up to
3 zones
independently. It is primarily designed for
latching
solenoid valves, although with a
simple modification it can also operate
non-latching
valves (e.g. standard 24VAC sprinkler valves), low-
voltage fish tank pumps, and other types of low-voltage DC or AC valves and pumps.
The package includes one assembled and tested OSBee circuit board in 3D printed enclosure, USB
cable, and (optionally) a USB power adapter (5VDC output, minimum 1A current).
2. Hardware Setup
OSBee has four terminals marked
COM
(common),
Z1
(zone 1),
Z2
, and
Z3
. The positive (+) wire (often
colored red) of each valve should be connected together and go to the COM terminal; the negative (-)
wire (often colored black) of each valve should go to an individual zone (1, 2, or 3). At the back of the
controller there are four big screws. Un-tighten a screw, insert the wire through the opening below it,
wrap the wire around the screw, then tighten the screw. OSBee is powered by a USB adapter through a
microUSB cable.
3. Software Setup
The first time you power on OSBee, or after each factory reset, the controller starts in AP (Access Point)
mode. In this mode, OSBee creates a WiFi SSID, the name of which is printed on the LCD screen (e.g.
OSB_xxxxxx). Use your smartphone, or laptop to connect to this WiFi SSID (there is no WiFi password).
Once connected, open a web browser on your phone (or laptop) and type in the IP address 192.168.4.1.
This should open the WiFi configuration page. The main purpose of the WiFi configuration is to let
OSBee know your home WiFi's name and password, so that it can subsequently connect to your WiFi. So
