You can make use of the ‘remote station’ feature supported by OpenSprinkler. Specifically, you can have one controller as ‘master controller’ and the other as ‘remote controller’. Any station on the master controller can be set as a ‘remote station’ (by giving the remote controller’s IP and corresponding station ID). For example, you can set ‘station 4’ on the master controller to point to any station on the remote controller. When you open/close station 4 on the master controller, it actually sends a command to the remote controller to open/close the corresponding station. This way, all stations are in one page (i.e. on the master controller). Hope this makes sense.
