add mdns discovery for network coordinators

[Tarik2142]

I described everything in the request here #https://github.com/Koenkk/zigbee2mqtt/issues/17430 I don't know much about typescript so improvements are welcome

Thanks for the PR, in order to get this merged:

• Make sure to add tests for this (npm run test-with-coverage should pass)
• Create a PR to update the docs (https://github.com/koenkk/zigbee2mqtt.io/)

Ok, thanks for the reply. I think there will be no problems with the documentation, but I've never written tests, so I'll have to figure it out. I ran a local check and somehow it passes. Here on github everything correctly shows that there are no tests for lines 85-115 I would be grateful for a hint why the local check is passing

Can you try to do a npm ci and then a npm run-test-with-coverage?

Unfortunately that didn't help so I'll look here sometimes. Also, I got a strange thing in the test system, when passing the LoggerStub to the Adapter, the logger for some reason still remains undefined and causes an error

why line 107 is uncovered? do i need to check all radio types?

[Tarik2142]

After the PR to the documentation, I will update the code and add a links to the documentation in the error messages

[Tarik2142]

So the links exceed the length limit, how should I shorten them?

@Koenkk PR to docs is ready https://github.com/Koenkk/zigbee2mqtt.io/pull/2028

@Tarik2142 I made some updates, can you check if everything is still ok? If yes, I will merge this.

[Tarik2142]

@Koenkk Tested the changes on my installation. Everything works.

Also tested handling of some errors, except the wrong packet, this requires changing the firmware of the coordinator

[Koenkk]

Great, thanks for this cool feature!

https://www.zigbee2mqtt.io/guide/configuration/adapter-settings.html#mdns-zeroconf-discovery If your coordinator supports this functionality, you can type mdns name in the configuration, IP, port and adapter type will be determined automatically. Even if the IP of the adapter changes, it will still be found. This simplifies the configuration
