Removal of dead device

The question has been up before, but I can't find a solution although searching through the forum :-(
Have a (battery) device, initially added as generic device, and unfortunately not removed properly.
Now it is simply impossible to remove it.
Have tried removing it by clicking the X at the device itself, using the "Remove a device" in settings, including it again (which results in a new unit with a new node-ID) and removing that device.
Get the following message when trying:
The unit has been "dead" for some week and I was hoping it disappeared by itself - but it's still there.
Looking at the graphic representation of the mesh ("157. unknown Z-Wave device"), it has 12 (twelve) connections - and I think it might be causing some delay in the transmissions...
Any suggestions?

The message you’ve mentioned, do you also get it when try removing from Settings or only when clicking on X? And what is that device actually?
I had the same problem with a couple of devices but when firmware 1.3.2.
One of them eventually removed after few attempts under Settings, Remove Device, the other was a stubborn Fibaro Double Relay 2. I had to reset this by holding the button while power on.
It will not cause any slower connection(s), as there will be no data to and from the unknown device
@danone: Yes, tried all possible combinations of what they write in the manual...
@caseda: Will the other devices not still try to use the routes they "know" according to the z-wave protocol and not until they've failed to get an aknowledgement a certain number of times over a given period stop trying?
@Fire69: It says so, yes, but it's still there - no matter the number of times I've tried to remove it, using the X or the option under settings :-(
Anyway, if it doesn't influence speed as @caseda says, it is more some kind of cosmetic problem - and maybe it disappears some day :-)
but even if it is a powered node, if a signal fails for 3 times to get an acknowledge back, it will timeout (and thus not use) for some time on that device route.

i know that better then anyone i guess but for a lot of people it will work
Looking forward to a solution. Somehow I have a feeling these doggy nodes screw up my z-wave performance.
The lag extremely annoying since I use a motion detector to turn the lights on in some rooms but now usually I enter the room, have to turn the light on manually, turn off the light manually and leave the room. Then maybe 30 sec afterwards the light is turned on by the flow .
I am not sure these nodes are the cause but I see no other reason for the lag..
For the future an option to remove devices (at least unknown ones) from the network graph would be nice
I have updated to the latest experimental f/w and was suggested to try the new heal button. Still no luck and stuck with a dozen alien nodes.
Apart from the heal function that is.
When I try to delete a device, it see a message that the device will automatically be deleted when it can't be found, that that doesn't do the trick.
After 15 seconds or so, I get a message: "vdevice.drivers.zwavebasic.pair.Connection timed out" - click close, and the device is still there.
When I look at the graph with the interconnections between the z-waves device, it's still there.
So +1 for removing the "solved" label.
Still think a way do remove devices from the Z-wave network graph would be a useful tool.
With Domoticz this was 'easy' ;-)
- Stop Domoticz (sudo service domoticz.sh stop)
- Modify zwcfg_xxxx.xml (sudo nano /home/pi/domoticz/Config/zwcfg_xxxx.xml)
- Find the ghost device-node (<Ctrl> W, id="nn" where nn is the node-number)
- Remove the sub-node with COMMAND_CLASS_WAKE_UP (Remove from <CommandClass... to - and including - ...</CommandClass>, including the two sub-nodes <Instance> and <Value>. Total 4 lines.)
- Save zwcfg_xxxx.xml (<Ctrl> S) and stop nano (<Ctrl> X)
- Restart Domoticz (sudo service domoticz.sh start)
- In the OZW console select the (now dead) Node and choose option Controller --> Remove failed Node --> GO (wait a few minutes)
- Restart Domoticz again. The Node will be there with status "Probe (Awake)". After a few minutes, the Node-state should be... DEAD.
- Stop Domoticz and power down the Raspberry Pi.
- After restart the Node should be gone.

They are unknown, the device table in Developer tools show they have no neighbors, but the graph does show neighbors
Can I discover what devices these are?
And if they are leftovers, how can I get rid of them?
Just kiddin'
I made a github issue in november. It must be on the to-do list of the Athom team. A was also in e-mail contact with @Emile but I gues the latest f/w release took over the agenda.
In November I was advised to be patient.
So, I am patient :-)
It just doesn't feel right to see this subject flagged as closed 'solved' as it obviously isn't.
As it is logged via Github, it will get addressed. So, my patience is with the Athom team.
Thanks for removing the flag 'solved'.
Another question, how does Homey handle polling time? Does it change automatically or do i need to change it for every device?
Polling is not needed 99% of the time with powered devices, as a state change is announced by the device itself.
If in case it is a battery device it can get the state when it wakes up, though that is not done for all capabilities as that creates too much traffic.
If it has polling (like greenwave devices) then it always is specified in the device's settings
