Zigbee2MQTT addon cleanup

Hello,

I’m in a house cleaning phase of my HASS running on rpi 4.
Currently running 2024016.

At some stage, I installed the Zigbee2MQTT addon.
Now no more in use.
I uninstalled the addon through HA UI.
However, according to supervisor log file, I still find the addon loaded.
I still have a directory zigbee2mqtt under HA main directory. Is it the reason ?
Can I simply remove this directory ?

Thanks, B.

Yes, if you have removed the addon.

You will also need to remove any retained discovery messages in your mqtt broker.
