I have installed HA in e new location/pi by restoring a backup from an other location/pi.
I deleted all devices from Zigbee2QMTT and paired new deviced in Zigbee2MQTT.
If I check in MQTT integration the deleted devices are still present but new created devices are not present.
I have also recently move Dongle sonoff P to dongle sonoff E.
on mosquitto broker log :
[15:02:50] INFO: Successfully send discovery information to Home Assistant.
[15:02:53] INFO: Successfully send service information to the Supervisor
In Zigbee2MQTT/configuration.yaml I see all devices I paired. and I see them also from Zigbee2mqtt dashboard and I can pilot them from it.
In MQTT integration I do not see new paired Elements.
In Home assistant dashboard or in HA automation I do not have access to Z2M devices.
