Someone help me learn how to set Zigbee2mqtt QOS please

Configuration
1

Hi all

TLDR: I have zigbee2mqtt set up and I thought it would be easy to set a QOS value. But I’m obviously stuffing something up as I cannot set a QOS. Can someone please point me to a good place to learn how to set this up?

Some detail: I’ve been into settings of all my zigbee devices and attempted to set the QOS value, but the setting value just disappears out of the box about 2 seconds after I enter it in, leaving it blank again. I’ve gone into the zigbee2mqtt/configuration.yaml file and manually entered a ‘qos: 2’ value for every device but it still doesn’t take. I’m testing with MQTT Explorer which is showing a QOS value of 0.
I’ve tried searching online but this doesn’t seem to be a problem for people as I only found 1 similar topic where no one answered that person. So I’m assuming I’m just doing something stupid as a noob or not using MQTT Explorer properly. Any help would be greatly appreciated.

Thanks
Alan

Did you stop Zigbee2mqtt before doing that?

3

No but I restarted HA after.

Always stop Zigbee2mqtt before you edit it’s configuration.yaml

OK, thanks. Will make sure I do that in the future.

Does that mean the settings won’t take hold now even though I restarted? Do I need to remove them, stop z2m and then add again.

Restarting HA does not restart Zigbee2mqtt

Ok, sorry, I think I get you now, since it’s an add-on it needs to be managed directly

Unfortunately though, still didn’t help as QOS still showing 0 after stopping z2m before making a change and then starting again.
