When I connect zigbee devices for the first time by zigbee2mqtt, I have the option to connect the end device by “permit join all” or join through an existing zigbee router.
So if I join through “all” does that mean the zigbee end device will route automatically through the best router onto the coordinator?
Or if I join through a permit join only through a router when joining the network, then the device is connected to the coordinator by that specific router. But what happens if that router disconnects for any reason. Will the end device route back to the coordinator by an another available router?
Feel free to point me towards any existing explanations on the forms or the Web. Im sure someone would have asked this before.
It’s also important to know that Xiaomi devices will join via the first device they hear from, regardless of signal strength. This means that for them it’s critical to use the option to join via a router you know is nearby.
Its so helpful that you mentioned that about xiaomi devices.
I have a few and I’ve experienced problem with them disconnecting. So I’ll add them again via the nearest router.
So as for the the whole mesh process, it’s fairly created on its own? Do zigbee 3 devices find their own path to the coordinator. Or is it better to add them via routers (lets say in terms of coordinator being on ground floor and the device on 2nd floor. So you should the device via router on 1st floor?)
