I have created an integration for Homebridge: https://github.com/timcharper/homebridge-opensprinkler
“Hey Siri, turn off my sprinklers” works, plus some other niceties.
There’s not a really good way to manipulate run-once programs with a valve-by-valve basis, so I haven’t implemented anything on that front yet. Would welcome input from the community / OpenSprinkler creator on how to best go about this.
