> Yeah that's my goal -- basically I want to be able to control the devices from anything web connected (and ideally, the same program running in multiple places). HomeAssistant provides a REST API for all devices connected to it. I don't even use its automation features, I just use it for the API to control my ZWave devices from other stuff. https://developers.home-assistant.io/docs/api/rest/ https://developers.home-assistant.io/docs/api/rest/ (POST to /api/services/ to control remotely) (Granted it's pretty heavy if that's the only feature you want, but hey, what you want does exist)
