Just installed an OpenSprinkler using a Raspberry Pi and some board I picked up on eBay a year or so ago.
Super impressed thus far, especially with the iOS app. Thanks to everyone that has contributed.
My original thought, when I was going to try and write my own, was that it would be nice to allow actions via email. So basically if the weather forecast shows more than a 50% chance of rain, send me an email. In the email would be a button offering to “cancel” that day’s watering. There would be no login or anything required, the link has a unique GUID for that request and it allows for an easy way to cancel the schedule if my look outside differs from the actual weather forecast.
Is it something that could be achieved?
