Yes, it’s true that the master station can only be one of the first 8 stations. so please add this constraint to your app too. Thanks.
I am very impressed by the interface you designed. Now, I haven’t tried it yet, but I am a bit confused how to get it running. From your instructions, I am guessing that this is a front end that runs on a local server which talks to OpenSprinkler and outputs a mobile webpage, is this correct? I would like to give it a try and blog about it. Thanks!
