Missing alarm codes for "electrical measurement" cluster.

Milivoje Bulajic

Other Parts Discussed in Thread: Z-STACK

As described in "Home Automation Public Application Profile" ZigBee document, alarms for "electrical measurement" cluster should implemented using alarm cluster. As I understand for that appropriate alarm code is needed.

I am unable to find alarm codes in publicly available documents, neither macro definitions in z-stack header files.

Best regards.

I don't read this in my latest reading to HA spec. Can you specify the document number and which chapter/section you read this?

ZigBee Document 075123r04ZB (page 142)

9.1 Electrical Measurement Cluster

9.1.2.1 Dependencies

For the alarm functionality in this cluster to be operational, any endpoint that

implements the Electrical Measurement server cluster shall also implement the

Alarms server cluster.

You can search ZCL_ALARMS for related codes in Z-Stack.

Well I searched z-stack for definitions and I was unable to find anything. I opened this topic in hope that someone with access to documentation will be kind to post alarm code definitions.

The Alarms related APIs are in zcl_general.c. You can refer to ZCL_ALARMS define in it.

Alarm code defines should be located in zcl_electrical_measurement.h but they are missing.
I double checked all files from /stack/zcl and I cannot find anything.

You probably mean document 075367r03ZB (the Home Automation standard) chapter 9. The document you mentioned is the Cluster Library Specification, in which no mention is made about those relatively new additions to HA.

Anyway, in 075367r03ZB 9.1.2.2.9.1 there is an example for AC Alarm Mask. It seems that the defines are missing from the Z-Stack Home 1.2.1 release, you might want to add them yourself.

You are right about document, 075367r03ZB is right one.

For alarm functionality alarm mask and alarm code definitions are needed.

Here is example for Power configuration cluster.

Alarm mask:

and alarm codes:

Does anybody know alarm codes for electrical measurement cluster?

It looks like the specification is currently incomplete and no alarm codes are provided for this cluster. You could try sending an e-mail to the Zigbee Alliance and report this.

Some googling has revealed that these clusters were originally proposed by Energy @ Home, and they are used by Centralite devices as well. None, however, specify alarm codes. My best bet would be just the but number as a code though the Zigbee specifications usually seem to prefer non-obvious solutions instead, so your mileage my vary. Good luck.
