In theory you can, but this is not implemented as a built-in feature. So if you want to do this you will need to modify the source code yourself. Here is a possible solution: for the salve controllers, you can modify the firmware to start the controller by default in ‘manual operation’ mode, this way you can use HTTP commands to open or close a valve individually.
For the master controller, you can change the firmware such that if a station to be opened or closed is on a slave controller, it sends an HTTP command to the slave controller accordingly. If you have some programming background, these shouldn’t be too difficult to do.
