@Chassy33 I also tested this today, and it’s working for me as well.

@Chassy33 Yes, that is correct. It was confirmed to me in a support ticket, and I also checked the code. In the javascript code, you can see that it queries the controller for its settings in this function:

https://github.com/OpenSprinkler/OpenSprinkler-App/blob/5818d27143e045dfc315348c752bfccb213a732f/www/js/main.js#L1146

And the controller replies here, putting the value of PIN_FREE_LIST in the response:

https://github.com/OpenSprinkler/OpenSprinkler-Firmware/blob/e9e04b006f82a29f2bd2317770a170402fe1bca6/opensprinkler_server.cpp#L1192

You can also find the spot where the UI code looks up the gpio list in the response.

I will be testing this myself when my controller arrives, as I’m adding a ninth zone with an external relay.

Just for others who find this discussion via search: The javascript UI now queries the controller’s firmware to find out the free GPIO pin list, so if the firmware is modified to add one or more pins to that list, the UI will correctly make them available.
