maybe AI is your friend? What I did once before is pull your device list up and copy it. No doubt theres an easy way to do it with json and the maker API, but I just plop it into excel and clean it to get the device name list.
I'll ask gemini AI to ID which ones are ZB 3.0
edit:
Well - that wasn't bad but it isn't accurate. no model numbers. sigh.
Trying Device Details Display app.
If you are comfortable privacy-wise, try dumping the output of http://[hub ip]/hub2/devicesList into an AI prompt.
That's wtat I needed. Copilot LOVES my build, lol.
Bottom line
This isn’t just a device list — it’s a very mature, power-user-level smart home system with:
- Multi-hub architecture
- Redundant presence tracking
- Full-room automation coverage
- Integrated security + environmental monitoring
The main trade-off you’re dealing with now is power vs. complexity.
Ok, now i'm bragging - but i wouldn't be here without this community! Now i'll have to find out if it can drag out a real "device list" that gives me MFR, model, and firmware details

Done. See linked thread above.

Not seeking assistance yet - just posting but when my ZB went sideways, it REALLY went sideways. more than 1/2 my devices are 'unknown'.
What did you have in mind when you shared this information here?

That looks terrible and I will leave the "good advice" to the guys in here who always come through for me.
Not a suggestion, but I have gone to the extreme of resetting entire radio and manually readding all (56) of my devices a few times over last 10 years. But in a couple of those experiences I would get to a point where a "bad" device getting added started the problem and then I had to eliminate it/them and do it all again. Again, not a suggestion for you, just an extreme I have suffered through a few times.
Good luck!
depending on answer, might want to break this out as well.

The post was supportive of the OP title - just my recent flavor of Zigbee Hell. Having been using HE since 2018, I've fallen many times with my Zigbee network and learned tons.
I wrote a journal of how I proceeded to repair it. Just not sure how to share that journal but it has some good stuff (I think) on tools and methods to recover.. My network now repaired:
(There is one 'unknown' device but I put it there purposefully)
If your interested in a document to read called "Hunting the Unknown:
Fixing a Broken Zigbee Network" please DM and I'll find a way to share.
