Help! Large Z-wave mesh very unreliable (migrating from smartthings))

When mine worked it was about 30sec a node

How many are z-wave? A single controller has a limit of 232 and the controller is 1 so real limit is 231.

On a healthy network it should not takes days to run a repair unless the controller is trying to query battery devices and that is causing a huge delay as it waits for timeouts.

225 are zwave. I have about 20 zigbee.

It’s taking about 5 to 10 minutes per node ...

Wild guess... mixed network of older z-wave and some z-wave plus?

Here is the zwave repair running ...

Yes

The older non plus devices are going to slow down the overall network and that includes the repair/heal/optimize process.

I get a lot of double events in my logs... see attached. Is this because the messages are repeating through their routes? Maybe this is the cause of my sluggish network?

Like I said ... never had this issue with smartthings (using the same amount of devices). Really don't want to go back to that platform as Rule Machine and Lutron integration is working wonders for me.

I'd say they are symptoms of the signal finding different ways through the mesh?
I see them time to time on mine, I'm trying to remove all my non plus z-wave devices to see if that helps.

This is off my own bat, support keep going quite

I gave up. I can't get hubitat to work reliabilty, even with a seperate hubitat on each floor.

The home I movedi into has rockwool in all the walls (interior partitions included) - so I'm making the assumption that its creating signal issues.

I'm going to try one last attempt. Bought 4 more hubitats and will try placing in. each. major. room. Fingers. crossed.

Have you looked into zniffing?

It's not expensive (uzb3 stick is like $30) and using a windows computer you can scan to see what's going on.

Also, as you build.
