Wired Ethernet has been supported since OpenSprinkler v3.2. It's implemented by using an external Ethernet module—ENC28J60 for v3.2 and W5500 for v3.3 and v3.4. If you have OpenSprinkler v3.2 or later and your unit did not come with a wired Ethernet module, you can purchase and install one separately. This page will guide you through the installation steps.
Step 1: Ordering an Ethernet module
If you didn't order a wired Ethernet module at the time of purchase, you can order it separately here.
Please select the module based on your OpenSprinkler hardware version, as the two types of modules are NOT interchangeable. You will receive the Ethernet module in a 3D printed enclosure, a 2x5 ribbon cable, and a 3D printed bracket.
Step 2: Unscrew the controller enclosure
Use a screwdriver to loosen the four screws on the back of the enclosure. Then insert the 3D printed back bracket to help hold the screws in place when you flip the controller upside down. (If you don't have the back bracket, use a flat object to cover the screws and flip the controller and object upside down together so the screws do not fall out)
Step 3: Connect the ribbon cable to the controller
Remove the top cover of the enclosure and locate the 2x5 receptor under the top circuit board. If this receptor is missing, your controller is an earlier version than 3.2 and does not support wired Ethernet.
Next, separate the top circuit board from the bottom, and insert the 2x5 ribbon cable into the receptor. Make sure the cable points up through the gap in the top board, as shown in the picture below
Step 4: Reconnect the top circuit board
Insert the top circuit board back onto the bottom. Double check that the female pins on the top board align with the bottom, as circled below. Misalignment will cause the controller to malfunction!
Step 5: Replace the enclosure cover
Place the enclosure top back onto the circuit. The 2x5 ribbon cable comes through the hole on the right. The hole is slightly narrower than the cable width, so lightly squeeze the cable into an arc to ensure it passes freely through the hole, as pictured below.
Step 6: Screw together the enclosure and connect the module
With the back bracket (or flat object) in place, flip the assembly upside down. Remove the bracket/object and tighten the screws on the back of the controller. Please DO NOT over-tighten screws. Finally, insert the other end of the 2x5 ribbon cable into the Ethernet module. The connector is polarized so it will fit in only one orientation, shown below.
