I'm unsure where this file is used?

+  -- 检查设备是否支持 Simple Metering 集群 (0x0702)
+  for _, cluster in ipairs(device.server_clusters) do
+    if cluster == 0x0702 then


we have other devices for which this would return true where we would not want your specific device's logic to be used, which is why we usually gate subdrivers via fingerprints

It is often the case that the driver init event happens before the radio is up after a hub restart, resulting in zigbee messages failing to be sent. I would recommend moving these to added or configure, since they likely do not need to be re-sent to the device every time they hub restarts.

+  local divisor = device:get_field(SimpleMetering.attributes.Divisor.ID) or 100
+  local multiplier = device:get_field(SimpleMetering.attributes.Multiplier.ID) or 1


this field is not likely to be set. We do set a similar field from "st.zigbee.constants": constants.SIMPLE_METERING_MULTIPLIER_KEY (and divisor) in our defaults, but we never use the attribute ID as a key,

+        {id = SimpleMetering.attributes.Multiplier.ID, value = 1, DataType = 0x22} -- 0x22 is 24-bit integer


we provide "st.zigbee.data_types" which has a Int24 (and Int32 constant)

in the ZCL this attribute is an Int24

It seems fairly obvious that your AI agent was not up to the task here.

our default handlers should handle this case, provided your device properly reports its simple metering multiplier and divisor.

Based on what you have here, I think all you need to add is the entry in fingerprints.yml. There does not seem to be any device-specific behavior that is different from our default handlers.
