Z-wave device stopped updating, now won't discover

[jefft]

Strange things happening... I noticed that one of my z-wave sensors, a Fibaro universal binary, hadn't updated any values in domoticz for 2 days. I forced a refresh in the zwavejs console, restarted the system, still nothing.

Deleted the domoticz devices for that node completely and forced rediscovery; only some of the node's devices have been discovered. Whatever I do, I can't seem to get the important ones - the sensors - to show up.

The domoticz log shows that it received the auto-discovery messages for the relevant devices:

Code: Select all

... yet only the root device and -1, -2 have entries in the domoticz devices list.

There are no records in the DeviceStatus table with those -3, -4, -5, -6 IDs, only the root and -1, -2.

Does anyone have an idea what I need to do to fix this? What could make domoticz report that it has discovered the device, but not create a device record for it; is there another list of discovered devices where there might be a stale record, perhaps?

These things are the temperature sensors on my ventilation system, so I'd very much like them working before it hits 40C tomorrow

Thanks!

Is it showing (and updating) correctly in the zwavejs2mqtt web interface ? Maybe you have to check the node groups ?

[jefft]

Yes, zwavejs console is fine. The node has the controller in both lifeline and another group.
What's odd, is that domoticz reports discovering the z-wave child devices but does not create domoticz devices to match. Feels like an issue between discovery and creation within domoticz. What happens between those two steps that could cause the devices not to be created?

[jefft]

@gizmocuz, it looks like this might be an issue with the MQTT topics.

zwjs2mqtt is publishing this device as 'zwave/9/49/4/Air_temperature', but I see messages for some devices as 'zwave/nodeID_101/...' and also the name, 'zwave/Node_name/...'.

I spotted that 'use node name' was set on in the zwjs console, so I tried switching that off. It didn't cause domoticz to create the devices, but it did stop most of my switches and plugs working!

Which MQTT topic format does domoticz want, and do you know how I can get zwjs2mqtt to send every node in the same format?

I'm puzzled; given the different topics that the messages can come in with, how does domoticz map them onto its devices? For example, one of my plugs has the ID 'zwavejs2mqtt_0xc7625338_111-37-0-currentValue' in domoticz, but the message sent to switch it on/off has the topic 'zwave/Kitchen_water_heater/111/37/0/targetValue' and its actual node name in the zwjs console is 'TKB Plug X'... how is the mapping between those IDs and names done?

Thanks!
