Particle.publish time to live (TTL) avail?

That's similar tothis thread

Particle.Publish TTL implementation status

The Firebase idea is the last example in my firebase tutorial, using Firebase for persistent variables to communicate data between Particle devices that are online at different times. Sure, it’s more work than having TTL support, but has the advantage of working right now, and you’ll likely easily fall in the free tier so it won’t cost anything.
