How to remove mqtt devices from VRM?

Hi

I'm using https://github.com/freakent/dbus-mqtt-devices to add additional temperature sensors to my Cerbo GX running v3.00

Having figureed out what I really want to display, I would like to go back to not having the additional sensors before I then re-add them how I'd like to see them.

I've removed them from the Cerbo - and made sure there is no remnant of them on DBus - but they are still present on the VRM dashboard - no sign of them on the devices list (but they never show there) and no apparent way to delete the 7 "HW (xxx)" entries on the dashboard.

Site is MSweet.

Can you help please?

Kind regards

John

The official front end fix is now in place and deleting temperature sensors from the device list will remove them from the dashboard as well. But for devices that don't appear in the device list that fix doesn't work.

Hi Guy & others

With a combination of the new functionality and some node-red gymnastics, I was able to remove all of the old devices from my system.

I sent the last-will disconnect message to remove the 3 active sensors from my system, but there were still 7 showing on the Dashboard but nothing in the Devices page.

I then re-added the 3 sensors to my system and now there were three entries on the Devices page so I resent the last-will disconnect and then was able to Delete them from the Devices page, but was still left with 4 ghosts present on VRM Dashboard but not on my system.

3 of these had been created with a different client code so I was able to recreate them on my system, and then remove them as above.

That left 1 ghost!

Using the Diagnostics page on VRM I could see it had a Product ID of 65535 rather than 41314 that the current version of mqtt-dbus-devices uses. So I temporarily changed the code to use 65535, recreated the device on my system, and then removed it as above.

All cleaned up and no more spooky devices.

I've also readded the 3 desired active sensors and all is working well.


Many thanks


John

Just to be clear, you can send the disconnect message (i.e. a message with connected: 0 ) with just a simple publish message to the correct topic. The Last Will will ensure the disconnect message is sent automatically everytime the remote device looses contact with the MQTT server on the GX device. This is why usage of a Last Will is strongly encouraged.

Thanks, but this was not the problem I had originally.

I had sent the last will message and the dbus entries were gone from my system, but there was no entry in the device list on VRM for any of my mqtt temperature sensors even though they appeared on the dashboard.

Can you explain in more detail what you did to resolve this, I have 12 ghosts on the VRM Dashboard, but none of them are represented on the Device page. I’m not sure that I follow on how to send ‘connected: 0’ and to where . I downloaded and installed 'mqtt-dbus-devices’ on my Pi, is there something more that I need, or can I send the bus message from the terminal with the mqtt-dbus-devices tool?

@mvader (Victron Energy) I know you are all busy with the latest release, but this is very frustrating - is there anything that can be done from your side to clear these ghost entries or provide a device list entry and delete button for them?

Many thanks

Kind regards

There must be a way to flush these ghost devices from VRM!

Many thanks

Hi @johnparVIC,

Nothing can be done yet.

It is definitely on the list for the VRM team to resolve, but keeps getting pushed due to higher priorities.

I won't forget about it though because I have the same issue on my own site.

Thanks Guy for the response - I'll be patient now that I know that it is on the list!

Have a great Holiday Season!

Kind regards

I have some Ruvi sensors registered in VRM that I disconnected from my GX device (I switched off Bluetooth), after a while a delete button appeared alongside them in the VRM Devices list. Perhaps you just have to wait a bit.

Hi @gone-sailing

I've had this problem since November 14th and no delete button because there is no entry in the device list for these items!

Kind regards

John

Hi @Guy Stewart (Victron Community Manager)

Just a thought - how about a simple filter for the UI where if no updates have been received for a few days, don't show these devices in the dashboard?

Kind regards

John

Hi @johnparVIC

The solution is in sprint now, so I expect an update in the next couple of weeks.

Hi there, any news about this? I would love to get rid of those. Or at least move them to the bottom of the list.1710846477515.png

@Martin Babic, Have you sent a disconnect message via dbus-mqtt-devices with "connected": 0 ?
For example:
{ "clientId": "fe001", "version": "v1.0", "connected": 0, "services": {"t1": "temperature", "t2": "temperature"}}

A device that is not connected should be able to be deleted in VRM.

Please read the dbus-mqtt-devices README, especially the secton on using the MQTT "last will" option to send a disconnect message on loss of MQTT connection.
