Hi, am new here, so please excuse if this was asked before.
can one use a 2nd OpenSprinkler main board as a ‘remote’ extension?
basically using the http commands a ‘master’ OpenSprinkler sends to a ‘slave’ OpenSprikler to control it like it would be an extension board.
I was reading a post where someone had a set of valves 200′ away and wanted to place the extender board close to it, but ended up running long valve wires instead.
Using two OpenSpriklers, both on the same network over WiFi could be a nice solution.
I am also looking into something like this to control multiple zones, each about 300-400 feet apart, but would be great to control them all from a single web-interface. That would mean that ONE OpenSprinkler would need to act as a master… (hope you get the idea)
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.
