mqtt autodiscovery in new domoricz release doesn't seem to work

[akamming]

i noticed the deprecated openzwave warning in the new stable, so i did some testing with z-zwave JS UI, following the steps at https://www.domoticz.com/wiki/Zwave-JS-UI. But unfortunately no devices are created.

the weird thing is there are no errors. z-wave JS UI initializes all devices. in the logfile in the container "/var/lib/docker/volumes/zwave-js-ui/_data/logs" no errors, i see zwave is initialized and sensor readings are received

in the domoticz log also no errors. Autodiscovery is switched on and the discovery prefix is ok. I also know mqtt is working, because i use mqtt for communicating with siri/homekit (homebridge) and that works fine (another prefix ofcourse)

how can i troubleshoot to find out what is going wrong?

nevermind: fixed it. apparently you cannot use localhost as hosturl for mqtt in z-wave js ui (which is weird, i use "localhost" for every other config on the machine). using the ip adress of the machine instead fixed it...

I had the same problem & sat for a couple of hours last night trying to fix things. I was convinced that it was my old version of Mosquitto that had caused the issue until I saw your post!

After update 2022.2 14716 domticz seems to give errors in using devices which have been added by mqtt auto in previous domoticz release . Every device is giving: "Error sending switch command, Check device/hardware (idx=6312)
Zwave-js is running correct. MQTT (mosquito) is running correct.
What an i missing here?

First, don't update to Beta versions if you do not really need to, to prevent getting into unexpected issues.
What happens if you disable/enable MQTT Autodiscover hardware (idx=6312)?

Hi Walter. The updaterelease does not work on my rpi3 system ( for 5 year) so i am always running updatebeta.
Disabeling MQTT Auto does not help or improve the situation. My MQTT AUTO Zwave-Js is realy f 'up since latest release..
I accidentally used the check for update menu item. Now i am in trouble....
Something has change in the authentication system of domoticz. I also had a hard time to get the docmoticz system working correctly again ( after the check for update item)
Had to recreate a user/password. I am complete surpriced by this move...
I thing something is wrong in the authentications routines ( domotics <-> MQTT) since the new release.

There is an automatic backup created during update beta. So you can revert back easily. See wiki https://www.domoticz.com/wiki/Raspberry ... eta_update

That ./updaterelease is not working and update beta does is very strang as it are basically the same scripts.

But don't revert to stable now from latest beta as there was already a datamodel update in the database which could give errors in stable.

So go back to the backup beta (and losing some measuring data) and after that it would be possible to update to latest stable 2022.2 (if you want)

I'm trying to update to Zwave JS UI, from OpenZWave, but don't get the autodiscovery working. No new devices are appearing:

• Mosquitto is working fine

• Z-Wave JS UI is installed an works fine, I can access it throught the web interface. I've updated all settings in JS UI according to the migration manual, like Activating MQTT Discovery, using the prefix homeassistant

• Enabled Accept new hardware in the Domoticz settings

• Added the MQTT AD Client in Domoticz, using the IP instead of localhost and using the autodiscovery prefix homeassistant

When I press update it looks like it is working fine:

Code: Select all

2023-01-04 18:52:40.794 Status: Zwave JS UI: Worker stopped...
2023-01-04 18:52:41.797 Status: Zwave JS UI: Connecting to 192.168.1.100:1883
2023-01-04 18:52:41.998 Status: Zwave JS UI: connected to: 192.168.1.100:1883

• Added the device names in JS UI and pressed 'save' in the setings several times to push status messages for all devices

• Tried to change the prefix into something else (zwavejsAD) in both JS UI and Domoticz

But still.... nothing happens. Does anybody know what can be the reason it is not working. Or how I can do some debugging?

[waltervl]

To debug check the debug section of the mqtt wiki. https://www.domoticz.com/wiki/MQTT#Debugging_MQTT
Especially check if zwavejs sends data to mqtt

Thanks for the tip, using MQTT explorer I indeed found that zwavejs was not sending data. And I found that the 'localhost' was also used in the MQTT configuration in zwavejs. Based on this topic I was under the impression that it was about the localhost in the Domoticz hardware configuration. Now I put the IP in both and it is working!

Hi guys,

I'm glad I (finally) found this post on the forum. It took me way too many hours to figure out why my migration from Open Zwave to Zwave-JS-UI wasn't working! Installing the Zwave-JS-UI was successful, as the web front end on port 8091 showed all my Zwave devices flawlessly. Yet none of them showed up in Domoticz! Inspecting with MQTT Explorer revealed that the information didn't reach Mosquitto. I saw just the Zigbee2MQTT data, but none from Zwave. And I couldn't figure out why! Until I found this topic on the forum in which akamming found out that you cannot use localhost as hosturl for mqtt in Zwave-JS-UI, but one has to use the ip adress of the machine instead! This contradicts with the instructions and the default.

So my strong advice is to add this information to the Wiki https://www.domoticz.com/wiki/Zwave-JS- ... _OpenZwave at the 4th bullit under the Basic Steps, describing the settings of the MQTT section in Zwave-JS-UI. In order to prevent others from searching this needle in the hay stack, like I had to.

Thanks,
Nick

Thanks for reporting, wiki is adjusted

[DomoNick]

Thanks!

PS. I see at the same time you also modified the contents of the html to add the Zwave-JS-UI as a custom menu in Domoticz. That still doesn't work for me. I get the option in the custom menu, but after selecting it, I get just an empty window. Any suggestions?

I had the same issue. You need to double check that your Zwave-JS-UI/Settings MQTT uses a real IP adresses not localhost! This will connect to the broker MQTT(MOSQITO).
You can check a log mosquitto.log it should have two connection one from homeassistnat one from domoticz. After that it will work in domoticz and show up the devices
