I just popped in to look for any updates, & I'm in that group you're describing- been happy with my Caseta product for the past few years, but wanting to make the jump. I have a RA3 processor sitting here & unsure which direction I'll go at this point.
Yeah, I am thinking there are more demand for ra3 support than is thought. Sounds like Hubitat isnāt going to support it so we started the migration of our systems and our customers systems to another, similar product. Was holding out hope for support but sounds likely it will never happen.
There are working reverse engineered integrations for Home Assistant, Homebridge, and OpenHAB. So all it would take is a competent developer (not me!) to create one for Hubitat. I believe, based on feedback from ChatGPT, that there are some Hubitat technical issues that might require a node.js proxy server, so not ideal.

You mean Lutron doesnāt support Hubitat. Itās Lutronās closed protocol.
I was surprised to hear @bravenelās estimate in the single digits too, but the exact number of us (I have a RadioRA 2 system) doesnāt entirely matter, if Lutron decides who gets access to the LEAP protocol.
It sounds like Hubitat would integrate with LEAP if Lutron ever decides to allow it.

I don't know the full the details to comment. By the way, others have been able to make it work without Lutron's "official" support.
Sure, thatās what @bill.d is referring to. A reverse-engineered solution. Which might be technically possible.
Hubitat as a company has said they donāt want to go that route. It could theoretically break the day after itās released to Hubitat users. That would be a lot of effort for nothing.
I donāt have full details of any of this either. Iām mostly going by what the staff say in threads like this one.

True, and I can tell you that even some guys who are friends with Lutron engineers cannot get anything related to LEAP; it is closed even to its own engineers. Let's see if they introduce Matter... lol

One option would be to spin up a Home Assistant instance, control RA3 devices from Home Assistant, and then interact with the RA3 devices from Hubitat using HADB.

And then Lutron breaks the HA integration...

I don't think Lutron will break the integration. They don't care and they don't change the way their apis work once released.
I think that illustrates the dilemma for a small company like Hubitat.
@danabw (and others) think a reverse-engineered integration is at risk of becoming null and void.
You (and others) think itāll be fine.
No one actually knows except the folks at Lutron.

I would argue that Lutron doesn't even know. Even if you were to be able to worked with Lutron on an integration, they change direction and you are back to square one. So, you are kinda in the same boat if you "reverse-eng" a solution.

I unfortunately read this too late and updated my Lutron system to radio ra3. Now Iām going back bc no integration is available.
Yeah, we had to migrate a bunch of customers to Home Assistant
