Z-Wave node missing in HA - visible in Logs and in other system

Configuration Z-Wave
1

Hi everyone,

One week ago I switched over from FHEM to HA and am very happy with it.

Today, there started to be a problem: I have some Z-Wave devices registered to a Z-Wave.Me ZME_UZB1 USB stick in my Raspberry Pi 4. One node (no. 34) does not show up inside HA, although there are many messages in the OZW log for that node (e.g. the node 34 reporting neighbors etc.). I cannot see any error message. In HA the node 34 does not show up anywhere.

When I switch back to FHEM with the same USB stick, node 34 shows up immediately. I have already restarted my ZWAVE network within HA 5 times with no node no 34 showing up.

What can I do to get the node back in HA - I am pretty sure it was there yesterday - and it registered with the USB stick and working fine within FHEM.

Any hints?

Update: I see some messages in OZW log now:

“ApplicationCommandHandler - Unhandled Command Class 0x31” (and other classes).

Update 2: Last reboots the node is visible in OZW log without any warning or error - same behavior as all other nodes (all Fibaro wall plugs). BUT: node 34 still does not show up in HA, in particular not in the Z-Wave node list.

Update 3: I don’t know, if this is of relevance: the node shows up in the zwcfg_.xml-File with this data:*

	<Node id="34" name="" location="" basic="4" generic="16" specific="0" type="Binary Switch" listening="true" frequentListening="false" beaming="true" routing="true" max_baud_rate="40000" version="4" query_stage="Complete">
		<Manufacturer id="0" name="">
			<Product type="0" id="0" name="" />
		</Manufacturer>
		<CommandClasses>
			<CommandClass id="32" name="COMMAND_CLASS_BASIC" version="1" mapping="37">
				<Instance index="1" />
			</CommandClass>
			<CommandClass id="37" name="COMMAND_CLASS_SWITCH_BINARY" version="1">
				<Instance index="1" />
				<Value type="bool" genre="user" instance="1" index="0" label="Switch" units="" read_only="false" write_only="false" verify_changes="false" poll_intensity="0" min="0" max="0" value="False" />
			</CommandClass>
		</CommandClasses>
	</Node>

This differs from the other Fibaro switches I have.

Many thanks, Oliver

What is your installation type? If you are running on Ubuntu or Debian host, try disabling ModemManager per the docs.

I am running the latest version of HASS on a Raspberry Pi 4.

This is my solution:

I removed the node from the zwave network through the configuration -> z-wave -> remove node option.

Then, I readded it through configuration -> z-wave -> add node option.

Now, everything is working again.

Great to hear :slight_smile:

Same problem, but every time I re-add I get a new ZWave node that never appears, and an “Unknown Node XX” (Old node #) shows up. The new node never shows up in the ZWave integration. The device and entities are there, but missing from ZWave config (node is added, messages in OZW log show it reporting in, and I am getting data).
