Well, this is a tricky question to answer and it depends on your specific setup. For example, here are two options to begin with:
– extend your valve wires to closer to where the office router is, so that OS can reach the WiFi signal, and still get physically connected to your valves.
– use WiFi range extender or set up a mesh network so the WiFi signal can reach further into the field
Thanks Ray for the reply
I am thinking maybe the antenna in the link only problem is I have 2x Os3.0 and they are in opposite directions
so may have to get 2 antennas
any suggestions are greatly appreciated
I would suggest that you send the controller back to us so we can replace the top layer with another board that has WiFi chip with external antenna plug. If it’s not convenient for you to send it back, you can purchase such a top board and replace it on your controller by yourself. In either case, you can submit a support ticket with the request.
