Getting tired of zigbee2mqtt discovery

Configuration Zigbee
1

my z2m is not finding devices no matter what i do.
sonoff dongle -e - with latest 8 version firmware, core mqtt broker. no success. not finding either the router (itead dongle 3.0 with router firmware) or any of the sonoff devices.

I am a bit confused - when you say Z2M is not discovering them - do you mean that you can’t see them in Home Assistant? Are they on the Z2M devices list?

The error says they are already discovered by HA, if you go to the Devices tab under the MQTT integration, do they appear there?

I have the same question. You’ll need to provide a screenshot of the z2m interface you’re seeing so I can help you.

so, after i made the post, did a try resetting the zigbee devices and i could see joining.
here is the current screen shot

trying to figure out why the two snzb-03 motion sensors are not getting interviewed successfully.

Also i noticed the coordinator is showing as having router firmware. i flashed it with 8.0.x coordinator just yesterday.

Device Type: Router does not mean it is flashed with router firmware. It simply means that this device can route zigbee signals and is not an End Device (which you would fully expect for a coordinator)

Regarding your motion sensors, try pairing again. There should be a pairing button on them - press that every couple of seconds so that they don’t go to sleep halfway through the pairing process. Battery devices tend to do that to conserve battery, and you need to keep them awake while they pair
