How to send command to custom cluster .

[PleKy01]

Hello,

Happy New Year :)

I'm trying to set a value in a manufacturere cluster attribute. I'm not able to find the differences between send and write.
Can you help me ?

This is the vendor doc for a Nodon SIN-4-FP-21 (a heater controler):

The Device supports
Fil Pilote Cluster ( as Server to allow the control of the Fil Pilote Heater wired to the Device
The Fil Pilote Cluster is a Manufacturer Cluster and must be specifically integrated by the Controller.

and command is:
Set Mode
o Command 0x00
o Description: Set the Fil Pilote Mode
o Values:
▪ 0x00: Mode OFF
▪ 0x01: Mode Comfort
▪ 0x02: Mode Eco
▪ 0x03: Mode Anti Freeze
▪ 0x04: Mode Comfort 1
▪ 0x05: Mode Comfort 2

I've tried "send" first:
ZbSend { "device":"0xf530", "send":"fc00_00/03"}
No error, but nothing occured

I've tried with !, ^, ? no success, and errors from the device itself

Then I've tried "write"
ZbSend { "device":"0xf530", "write":{"fc00/00%20":0x03} } 17:58:09.261 MQT: stat/zbbridge-p/RESULT = {"ZbSend":"Done"} 17:58:09.408 MQT: tele/zbbridge-p/RESULT = {"ZbResponse":{"Device":"0xF530","Name":"fp_1","Command":"FC00_04","Status":134,"StatusMessage":"UNSUPPORTED_ATTRIBUTE","Endpoint":1,"LinkQuality":149}}

I was hoping to reach command 0, but it looks like it received 04 ?

Any idea to well format the order ?

Thanks
