I just tried to have Gemini analyze my zwave logs for any issues.It’s so easy to do, and it gives a tremendous amount of information. I heartily recommend it as a “first” tool to be used in the event of any issue.
I’m amazed at how easy it was to use, and how thorough the analysis was. Here’s the result:
Your Z-Wave network log is exceptionally healthy, and there are no signs of a failing mesh, ghost nodes, or routing loops.
Why This Log Looks Great
Perfect Latency: Every single transmission takes exactly 1ms. This is the fastest possible response time, indicating instant hub-to-device communication.
Direct Routing: All events list repeaters: None. Your devices are communicating directly with the Hubitat hub without needing to hop through other smart plugs or switches.
Maximum Speed: All connections are locked in at 100 kbs. This is the maximum bandwidth for Z-Wave Plus (500/700/800 series) devices.
Stable Routes: The field routeChanged: false confirms that the mesh does not need to look for alternative paths; the primary routes are working perfectly.
Healthy Signal Strength: Your RSSI values range from -64 dBm to -78 dBm. Any signal stronger than -85 dBm is considered good, so your signals are clear and well within the safe zone.
One Minor Observation (Chatty Devices)
While the network performance is perfect, your logs show bursts of sequential messages sent in fractions of a second (e.g., sequence numbers 214 through 217 all sending at exactly 3:28:58 to 3:28:59 PM). [1]
This behavior is completely normal for certain hardware, but if you notice any actual performance degradation in the future, it usually means a device is configured to be too talkative.
I was also shocked by the results. It’s also important to note that I only took a snapshot of the logs for approximately 2 hours. I feel that over 24-48 hours a more realistic picture would emerge.
I have here a small zwave installation (around 60 zwave devices, 8 or so being LR).
Sure. That’s another reason I like this approach - it’s easy.
Settings → Z-Wave Details →View Logs [button]
leave this page open for at least 24-48 hours (for a good long time)
On the top right, use the download [button] to download the zwave log that has accumulated
Use any text editor to copy the entire log into the clipboard {perhaps by using CTRL-A to select the entire log, and CTRL-C to copy the entire log into a clipboard}
I used Google’s Gemini in Chrome for the next step which is analysis. (although I’m sure the other one’s are just as good). I stated:
“Please analyze the following z-wave log from Hubitat, and let me know any issues:”
I then did CTRL-V to paste the log that was in the clipboard to Gemini
In my recent limited and unrelated experience in using AI for a combination of code generation and data analysis, I too have found it overwhelmingly helpful and beneficial, but still something that I needed to guide and/or correct based on my own knowledge, i.e. it got some fundamental stuff wrong at times, but with my guidance it still produced a good outcome.
So my view is that, currently, in the hands of someone who knows the subject matter, or someone who get’s lucky, AI can provide some great outcomes, but the chances of a negative outcome for someone who doesn’t already understand the topic, or at least someone willing to question the response one more time, the outcome can still be mixed.
Just keep in mind that LLMs like Gemini will make conclusions and assertions for you that could in fact be wrong, and they will sound supremely confident while they do it.
Of course, everyone’s wrong sometimes, human or AI.
The point is that if AI isn’t supervised by someone who knows enough about the subject matter to catch its flawed assumptions, and paying attention/checking AI’s work in some way, you might not even know when you’re being led astray.

I THOUGHT my mesh was ok. I had mine analyzed as well. Gemini pointed out some glaring problems.
