Block device from rejoining network

[brandflugan]

Hi awesome developers!
I've seen some similar posts to my problem where a device is auto rejoined after being removed, which can be solved by resetting the device.
Since devices sometimes are owned by others (neighbours) this solution is not always applicable.

I've seen that Zigbee2MQTT offers the option to block a certain device from rejoining your network again.

Would this be something that can be added to ZHA?

Best regards

Hi Markus,

Generally, there isn't a way to block devices from joining a Zigbee network. All you can do is politely ask the device to leave if it's detected on the network. This is what removing a device does in ZHA.

Do you have a device that rejoins after being asked to leave? Unfortunately, once a device has your network key it's part of the network. The best we can do is ignore packets from it and ask it to leave. This won't prevent the device from communicating with other Zigbee devices directly (e.g. a motion sensor that sends group commands) or from using up network bandwidth.
