Hi, this is Pavel here. About ten years of IoT experience, including 3+ yrs. with Zigbee.
Is it possible to look at the docs for the device in question? Something describing the supported profile and clusters/commands/attributes. What chip/Zigbee stack is that device based on?
There obviously will be a way more question, but first I need some basic info to start with.
Thanks,
WBW,
Pavel.
