[SOLVED] MQTT not working on 2.4 (already tested all suggestions in other topics)

Add-ons Bindings
1

Hi all,
I am really puzzled. In my production environment I have upgraded from 2.3 to 2.4 stable (using openhabian).
After the upgrade MQTT (V1.13) binding does not seem to work anymore, in a sense that items linked to an MQTT topic don’t get updated.

I use textual configuration (addons.cfg).

I have checked the suggestions found in other threads such as:

  1. enable legacy bindings
  2. remove and install the binding
  3. increase the log level in Karaf to check for errors

None of this helped me finding the cause.

from Karaf console:

openhab> bundle:list -s | grep mqtt
225 x Active   x  80 x 1.13.0                 x org.openhab.action.mqtt
244 x Active   x  80 x 1.13.0                 x org.openhab.io.transport.mqtt
256 x Active   x  80 x 1.13.0                 x org.openhab.binding.mqtt

Attached is the log of mqtt binding during startup:

transformation files:

inverted-contact.map

CLOSED=0
OPEN=1

and

inverted-binary.map
0=ON
1=OFF

I am stuck now.
Any idea to resolve the issue?

adding Karaf output for MAP transformation:

Have you cleaned the cache and rebooted?

I’m a bit suspicious about your logs, the entries for the mqtt binding are lacking the “mqtt1” which I would suspect for the use of the legacy binding.
Can’t check my system atm (staying at Catania the next weeks)

What does PaperUI show as installed mqtt binding, 1, 2 or both

5

I have rebooted several times.
How do I clean the cache?

6

PaperUI shows installed only mqtt1 (V1.13).

7

Use the following commands:

sudo systemctl stop openhab2

sudo openhab-cli clean-cache

sudo reboot
or
sudo systemctl start openhab2
if you prefer not to reboot again.

Also, if you don’t need the mqtt action binding then I would remove it and use only the mqtt binding.

Hi,
I have removed the mqtt action and mqtt started to work again.
So they are incompatible somehow.

Very weird. This should have been stated in the release notes as a breaking change…

It’s been an issue (or has caused issues) with mqtt 1.x even on earlier versions of OH.

Hi,
thanks for your reply.
Actually with previous version (2.3) I never had any issue with regards to the presence of both MQTT binding (V1.13) and MQTT action.

Anyway, I am happy that I solve it, but there should be a note saying that the two elements are incompatible.
