Need periodic MQTT updates for AC powered z-wave plug

[AlfaBravoX]

Hi community,

my use case is to setup dashboard with mqtt controlled z-way elements (switches and thermostat). I need to mark different color of those elements that were not sending MQTT heart beat over 5 minutes.

For frequently waking up battery powered devices it is not a big problem, because after wake status is changed and mqtt message is fired on, but the probem is with AC powered z-wave devices ie. plugs. These are not sending regular updates.

Using z-wave/_CLIENTS/ZWAVE_GATEWAY-office/api/driverFunction and payload '{"args":["const nodeId = 1; const node=this.zwaveClient._nodes.get(nodeId); return node.lastActive"]}' is not good solution for me because I'd like to stick to this topic only: z-wave/myNodeId/37/0/currentValue

Any ideas how to enable ZWJS UI to send periodic MQTT updates/heart beats on above mentioned topic would be appreciated

Cannot you use lastActive topic?

Alternatively you could use Scheduled jobs in order to make zui programmatically send updates but I prefer the first solution

Unfortunately z-wave/myNodeId/lastActive does not emit anything regularly. Currently timestamp is 2 hour late even thought UI last timestamp is just 30 mins old. So it is not even in sync with UI.

Strange, it is updated every time stats are emitted:

zwave-js-ui/lib/ZwaveClient.ts

Line 5429 in e38b13f

if (stats.lastSeen) {

@AlCalzone is lastSeen always set in stats?

[AlCalzone]

It should always be set when there's communication with the node. @AlfaBravoX please make a driver log, on loglevel debug, set it to save to file.

When this happens again, share that log and the <random-number>.jsonl file from your store directory. Attach them here as a file (drag & drop into the text field).

You can see that lastActive topic is 3 days old, however UI is uptodate:

Client (null) received PUBLISH (d0, q0, r1, m0, 'chbk32-z-wave/myNodeId/lastActive', ... (44 bytes))
{"time":1694434125943,"value":1694434125596}

cc @AlCalzone I don't see anything wrong here at first sight

@AlfaBravoX I'll need some more context here:

• Which is your actual home ID? d30c5c0f or de583a74? Check the info icon in the top right corner to see.
• Which node ID is this example for?

[AlfaBravoX]

zwave-js-ui: 8.25.1.9b831e2
zwave-js: 11.14.2
home id: 3540802575
home hex: 0xd30c5c0f

does it help?

[AlCalzone]

Which node ID is the above example for?

[AlfaBravoX]

The only node that is AC powered is node 6. The issue is there are no periodic MQTT updates for AC powered z-wave plug, node id 6.
