Zigbee2MQTT Link Quality messages

[iridris (Steven)]

In Zigbee2MQTT, are link quality messages separate messages? Or is it pulling the LQI value from other messages passing on the mesh?

Looking at my activity log in Z2M, the majority of the messages are just reporting minor fluctuations of LQI with no other actual values changing. These messages aren’t very useful to have so frequently - so I’m wondering if they can be tuned down for a quieter mesh.

LQI is listed as a value on the “Exposes” tab, but I don’t see it listed on the “Reporting” tab.

No, they are part of the state update topic that Z2M publishes:

z2m:mqtt: MQTT publish: topic 'zigbee2mqtt/Motion Stairway 1', payload '{"battery":100,"device_temperature":22,"illuminance":3,"linkquality":91,"occupancy":false,"power_outage_count":1182,"temperature":31,"voltage":3035}'

Z2M needs to know the quality of each device’s signal and LQI is a pretty big part of that.
I wouldn’t worry too much about having a quieter mesh. Go to Settings > Health inside the Z2M interface and sort by “Messages per sec”. As long as the values are reasonable (less than 1 message/s), then your mesh is fine.

I did not know about this so was curious, I don’t see a list of messages?

Or is this in the new UI?

It’s in the new Windfront UI. Still getting used to it, but it has some pretty decent features.
