Create custom cluster for device

[samChanFarm66]

Hi all, it is my first time to use zigbee2mqtt and I have some question - Is there any method to create custom cluster for device?

I have a zigbee module which cluster id: 0x08FC can be used.
I tried to edit the cluster.js file at "node_modules/zigbee-herdsman/dist/zcl/definition/cluster.js" , to add the cluster to it and it works perfectly.

However, I don't want to edit the source file.
May I know is there any method to declare a custom cluster similar to add device by "external_converter.js" ?
So cluster can add cluster externally.

Thank you

For what device is this? Currently clusters can only be added by adding it to cluster.js

I see, then I will use editing .js method to add custom cluster.
It is a Zigbee to Serial module, that cluster is to pass received payload to UART.

Thank you for your help.

I have a related issue, I am working with a device that uses the cluster
64515 0xFC03 but that is already defined as manuSpecificPhilips2

this device uses quite custom clusters and I also do not think they should be added to cluster.js. Is there a way to add the clusters per device or at least to disable the defualt handling ?

It can be added to cluster.js but with a manufacturer code (e.g. https://github.com/Koenkk/zigbee-herdsman/blob/master/src/zcl/definition/cluster.ts#L4165). Not that this only has to be done if you want to have commands/commands reponses, if you just want to support attributes it is not necessary to do this.
