Just had another look at the Sprinklers.php posted by Dan. Although he has the OpenSprinkler at 192.168.1.55 in his instructions, and in the first part of the php file, there are a couple of references to 192.168.1.18 later in the code. If you edit these to be the same as your OpenSprinkler IP you also get the next weeks schedule printed after the logs. Even better, if you enable a rain delay, you see the schedules that won’t be run in red!
Didn’t even realise that was there – an added bonus – great work Dan!
