A few days ago I discovered it’s possible to use IFTTT with OpenSprinkler, and this is much more powerful than pushingbox because IFTTT supports a larger variety of triggers and actions, including using Amazon echo to trigger actions. I wrote a blog post here:

so we will be switching from supporting pushingbox to supporting IFTTT in the firmware instead.
