How to read attributes

ON/OFF switch can only send ZCL ON/OFF/Toggle command and doesn't support ON/OFF attribute on itself. Do you mean to request ON/OFF status on light device?

I want my switch to send its status(On/OFF) to my coordinator so that i could check whether the swicth is in on state or off state currently

Does your switch device support ZCL ON/OFF cluster server?

Yes. I got my switch binded to two lights(ZED) and I can control the lights from my switch.

Then, your switch won't support ZCL ON/OFF cluster server and you cannot do ZCL on/off attribute read to your switch device.

1) By cluster Server do you mean OutClusterList or InClusterList?

2) Actually I'm new to ZigBee so I'm a little confused between InClusterList and OutClusterList, can you please elaborate on this?

3) Which ClusterList on a source device gets compared and matched to which ClusterList on a destination device to do a binding?

1&2. Cluster server is mapped to InClusterList and Cluster client is mapped to OutClusterList.

3. When binding, you need to give endpoint and cluster you want to.

3) I know that to do a binding, we need to provide EP and cluster, what I want to know is when we send a ZDO_BIND command to make a binding between a source and a destination device, which ClusterList(InclusterList or OutClusterList) on the source in compared and matched to which ClusterList(InclusterList or OutClusterList) on the destination to do a successful binding. Suppose we are using cluster 0006
