Hi, I am using some opensprinkler 3.0, DC latching controllers on my farm. I am using a Ubiquiti Nanostation to provide long range wifi so I can access them. The furthest one currently is 1km away from the Nanostation and usually works fine although the signal is weak and web interface sometimes refuses to respond until I reboot it. Mysteriously I can ping it no problem, at all times.
As the farm expands I need to put some more controllers further away. I was wondering if it’s possible to buy an OS3.2 controller with a RP-SMA (or similar) port for an external antenna. I need 2 more controllers, but I can’t see any option on the products page to specify an external antenna version of the controller.
When you place the order, you can leave a note saying you want the external antenna option. So instead of the standard ESP-12F, the controller will come with ESP-07S WiFi chip, which looks like this: https://www.mouser.com/datasheet/2/975/1494602250ESP-07S_Datasheet-1589078.pdf
and you can plug in an external antenna. There is no surcharge, so all you need is to leave a note. There will be a one-week lead time as we don’t normally stock these versions.
