Hi,

I have a Danfoss Thermostat connected to my coordinator.

I also have the ZigBee Cluster Specification of the thermostat. (Link)

I've tried to use AF_DATA_REQUEST

<TX>12:37:03.48 COM4 AF_DATA_REQUEST (0x2401)
    DstAddr: 0xE195
    DestEndpoint: 0x01
    SrcEndpoint: 0x01
    ClusterID: 0x0201
    TransID: 0x01
    Options: 0x00
    Radius: 0x1E
    Len: 0x05
    Data: ...Q@ (0x10, 0x01, 0x00, 
                0x51, 0x40  ---> custom attribute has value 0x4051
                )

But I get this message in return:

<RX>12:37:07.41 COM4 AF_INCOMING_MSG (0x4481)
    GroupID: 0x0000
    ClusterID: 0x0201
    SrcAddr: 0xE195
    SrcEndpoint: 0x01
    DstEndpoint: 0x01
    WasBroadcast: 0x00
    LinkQuality: 0x54
    SecurityUse: 0x00
    Timestamp: 0x00614CD9
    TransSeqNumber: 0x00
    Len: 0x06
    Data: ...Q@. (0x08, 0x01, 0x01, 0x51, 0x40, 
                 0x86 --> the value should be either 0 or 1
                 )

Any suggestion?

Luca

Can you use sniffer to check what exactly exchanges over the air and attach sniffer log for us to check it?

Unfortunately I can't use a sniffer. I don't have the hardware nor the money it.

Does ZStack 3.0 support manufacturer attributes?

0 YiKai Chen over 4 years ago in reply to Luca Vetri

What do you mean manufacturer attributes? Is it custom attribute? Basically, it should be no problem if you follow ZCL cluster/attributes mechanism.

0 Luca Vetri over 4 years ago in reply to YiKai Chen

If you look at the link you can see the manufacturer attribute being already embedded inside the danfoss thermostat.

Do you setup sniffer to check it?

0 Luca Vetri over 4 years ago in reply to YiKai Chen

As I said above unfortunately I don't have the ability to set up a sniffer.

Didn't use any sniffer to check it, but I assume that is somehow embedded inside the danfoss thermostat. Also because the document I linked is supposed to be used by developer to implement the thermostat.

For experienced developers, the document might be enough but since you have problems, sniffer would be a best tool to verify what command you send and what the device responds.

Hi Luca,

0x86 represents a ZCL_STATUS_UNSUPPORTED_ATTRIBUTE, and Z-Tool is not concerned with manufacturer attributes since it does not have a ZCL layer. Instead, everything is processed at the AF layer hence the AF_* MT commands. This Attribute ID is also listed as optional in the Danfoss spec.

Regards,
Ryan

Is there any way to activate it?

0 YiKai Chen over 4 years ago

try to reverse the order of 0x404E that you input to ZTool.

Nothing. I assume it is not implemented; which confuses me since I don't understand why they added them in the Danfoss Spec.

Maybe try to contact Danfoss to make sure you have correct firmware running on your device.
