Cluster List for Thermostat Sample

If you take a closer look in the TI wiki, you should find ZCL_CLUSTER_ID_HVAC_THERMOSTAT should be put in zclSampleThermostat_InClusterLis of Thermostat device. For Heating and Cooling device, ZCL_CLUSTER_ID_HVAC_THERMOSTAT should be put in zclSampleHCUnit_OutClusterList. I think you mix up Thermostat and Heating and Cooling device. They are different.

They are in the TI wiki. But, if you take a look at the newest Z-Stack Home 1.2.2a, the ZCL_CLUSTER_ID_HVAC_THERMOSTAT is put in InClusterList. Heating and Cooling device configuration looks like this:

#define ZCLSAMPLEHEATINGCOOLINGUNIT_MAX_INCLUSTERS       4
const cId_t zclSampleHeatingCoolingUnit_InClusterList[ZCLSAMPLEHEATINGCOOLINGUNIT_MAX_INCLUSTERS] =
{
  ZCL_CLUSTER_ID_GEN_BASIC,
  ZCL_CLUSTER_ID_GEN_IDENTIFY,
  ZCL_CLUSTER_ID_GEN_ON_OFF,
  ZCL_CLUSTER_ID_HVAC_THERMOSTAT
};

#define ZCLSAMPLEHEATINGCOOLINGUNIT_MAX_OUTCLUSTERS       1
const cId_t zclSampleHeatingCoolingUnit_OutClusterList[ZCLSAMPLEHEATINGCOOLINGUNIT_MAX_OUTCLUSTERS] =
{
  ZCL_CLUSTER_ID_GEN_BASIC
};

Hmm, so could you tell me if I understand this mechanism properly:

Temperature sensor sends data (temperature value) to Thermostat, so ZCL_CLUSTER_ID_MS_TEMPERATURE_MEASUREMENT is put in InClusterList for Sample Temperature sensor device and in OutClusterList for Thermostat device. Sensor is the data server in this case and the Thermostat is the client on this cluster. I understand this configuration, it's clear for me. 

Now relation between Thermostat and Heating/Cooling Unit. In this situation Thermostat sends data to Unit, isn't it? So the Thermostat is the data server and Unit is the client on this cluster, right?

So why should ZCL_CLUSTER_ID_HVAC_THERMOSTAT be put in zclSampleHeatingCoolingUnit_InClusterList? Heating/Cooling Unit receives the data, not send.

I know that thread, it helped me to understand mechanism of input/output clusters. But I cannot find answer for my question there.

So, in this example of sample temperature, the IN cluster list contains MS_TEMP, so zclEZModeInvokeData.Inclusters contains MS_TEMP so that it can find a matching node with MS_TEMP defined in the OUT CLUSTER, which is the thermostat node. In this case, the temp sensor is the data server, and the thermostat is the client on this cluster. 

I agree. If device sends data, you put its cluster to OutClusterList of device, if it receives data, you put its cluster to InClusterList to find a matching node. 

And the same for the matching between thermostat and heating cooling unit.

Actually it's not. Heating/Cooling Unit receives data and you told me that its cluster should be put in InClusterList. WHY?

Could you refer to my previous post?

What do you mean Heating/Cooling Unit receives data?

I mean that Heating/Cooling Unit receives data from Thermostat device.

from TI wiki:

Heating/Cooling Unit has the ability to receive the report command sent by the thermostat device and decide whether to enter heating or cooling mode based on the temperature value reported.

What about this sentence:

 If device sends data, you put its cluster to OutClusterList of device, if it receives data, you put its cluster to InClusterList to find a matching node. 

Is it correct? If it is, why should ZCL_CLUSTER_ID_HVAC_THERMOSTAT be put in zclSampleHeatingCoolingUnit_InClusterList, since Heating/Cooling Unit receives the data, not send?

According to that, if SampleTemperatureSensorDevice only sends ZCL_CLUSTER_ID_MS_TEMPERATURE_MEASUREMENT message, why it is put in InClusterList? The same analogy.

YiKai, I'm sorry, but I get the impression that you don't read my posts.

In SampleTemperatureSensor example, ZCL_CLUSTER_ID_MS_TEMPERATURE_MEASUREMENT is put in inCluster.

Okay, it's correct. SampleTemperatureSensorDevice sends ZCL_CLUSTER_ID_MS_TEMPERATURE_MEASUREMENT message to Thermostat device, so it is put in inCluster. If I want to send data I put its cluster to InCluster, right?

SampleHeatingCoolingUnit only receive ZCL_CLUSTER_ID_HVAC_THERMOSTAT messages so ZCL_CLUSTER_ID_HVAC_THERMOSTAT is put in InClusterList.

SampleHeatingCoolingUnit receives data from Thermostat device. So why ZCL_CLUSTER_ID_HVAC_THERMOSTAT is also put in inCluster? This is my question.

If you have to provide attributes of temperature cluster to read by other nodes, you have to put temperature cluster to inCluster.

If your device can report temperature data, you have to put temperature cluster to outCluster to let other node knows it can report temperature data.

Could you explain me what's the difference between these?

If I understand it properly - there're two states:

1) device sends data (then it's data server)

2) device receives data (it's data client)

What's the difference between  a) providing attributes cluster to read by others and b) reporting data to announce others that device can do that? Both are 1) state - device sends data, right?
