Good news - there’s a community HACS integration available now that works with OVOS/Neon to bring your Notify automation back to life: Home Assistant Integration for OVOS/Neon
I do intend to keep this one up over time and PRs are, of course, welcome to add functionality!
The Home Assistant skill/plugin combo that @JarbasAl linked to is the one that is being maintained and rolled into CommonIOT for OVOS 0.0.9 (still a couple of releases away) so if you’re using OVOS, that’s the recommended path. The original HA skill is still being actively maintained so if you have that working on OVOS, by all means, use that! Just be aware that come OVOS 0.0.9 there will be some intent collision that could cause issues.
I check this forum a couple times a day, but if you have questions, the Matrix chat is usually pretty busy. Or if you don’t mind delayed responses I’ll keep an eye on things here as well.
