That nullPointer occurs when you don't do a Save Preferences after the Initialize. But I will fix it by stuffing in a default value during Initialize().

When queried the device is returning the code 86, which means Not Supported. I get the same thing on my Third Reality. Doesn't mean that your device doesn't route properly, just that it has not implemented the method to access that information. I'd like to figure out which ones do and which don't, along with their relative signal strength.

To that end, can you please send me the device information from the device data area like this:

Thanks.

That is interesting. What do you get at that address when you use the hub ip?

Could you please provide the device data so I can add it to post #2, the compatibility list. I'd like to get the top 10 or 20 documented.

24

I'll check once I'm home but it should be nothing as my network is basic and all at 192.168.1.x

25

Nothing in device sata it is this.device.

@danabw This the is unfamous "Hubitat F2 bug" - something weird happens during the pairing and Hubitat picks up the wrong Green Energy cluster ...

Assign temporarily the forked Markus's Zigbee repeater driver.

Then delete the repeater ("REMOVE DEVICE" red button).
Pair it again - it should pick up Markus's driver this time, and the endPointId shoube be 01
Then you can switch to Gary's driver.

Thinking about the process to use this driver w/my SonOff dongles...I have three of them on my C8, two of them are active repeaters. If I remove and re-pair them I'm going to break all those existing routes/repeating, right?

I've only just gotten my Zigbee mesh stable in the last few weeks, after months of problems since the C8 released. I really can't do anything that might throw my mesh back into instability - WAF is well into the negative and rebuilding very slowly. One of my dongles hasn't been doing any repeating as far as I can tell, so I could "sacrifice" that one...

31

Ya its a bitch to re-pair it as have to open case and press buttons and only Way i got them to pair was immediately following a firmware flash...not worth the trouble.

You have to click Configure and wait a few seconds to get the Device Data.

33

Most probably - yes, although I can not be sure.
So, it may be wiser to postpone this operation for a better time...

Here, I still have WAF credits after installing these Nanoleaf Strip LEDs in the kitchen - they can be turned super-bright, exactly what my wife was asking for! (I am lucky she didn't ask me how much these cost! :slight_smile:

Yes, that is as expected. I'm finding not every device supports this functionality which is why I broke out retrieving Neighbors and Routes as two seperate options.

I notice you still have some preferences from your old Driver. It's not a problem, just means that you didn't do a Wipe so you will have attributes and state hanging around from your old driver.

To get the cleanest display, do a Wipe, Initialize, browser refresh (F5) and leave the Device Data Collection Mode at Neighbors Only then Save Preference. Routes are nice to have but Neighbors has the more actionable information because of the LQI data.

Also, on your next cycle of collecting Device information the addresses will reconcile to names for easier reading.

Not exactly: The neighbor data is picked up immediately. Routes are wiped out and get rebuilt as necessary.

Immediately (10 seconds) after power cycling

What does happen though is that any child relationships of devices hanging off that repeater are lost when you do a delete and re-join. Those devices will then start the process of trying to find a new parent.

I have found with end devices I can just initiate a new pairing request and the device get's re-joined to the same device definition, but with a newly issued 4 digit zigbee address. I think the same would be true of a repeater but I have not yet tested that out. If it's true I would expect it would retain all of the same child relationships.

36

Yes did a wipe multiole.times

37

I'm seeing some settings in your screenshot such as illuminanceAsMotion and vMaxSetting for example that should have been erased by a wipe.

A wipe should have log entries like these:

You are doing a Wipe without entering any parameters?

No project, however well intentioned, can survive negative WAF for long.

Things didn't quite go as expected when removing, rejoining.

Set up the dongle w/Markus' driver. Initialized, etc. (And used Device driver to clear everything before the change to Markus).

Removed dongle from the hub and re-joined it. But came in as...huh? :slight_smile:

So after pairing finished I had this in data:
2023-11-12 11_40_37-Hubs, Network, & Tech

Changed to Markus's driver and got this:
2023-11-12 11_41_23-Hubs, Network, & Tech

Changed to this driver and got this:
2023-11-12 11_42_47-Hubs, Network, & Tech

Then did a wipe w/this driver and all the initialize/etc. steps in OP, and ended up w/this in Data: :slight_smile:
