[Device Support Request] Develco Frient ZHEMI101 Electricity meter reader

Is your feature request related to a problem? Please describe. Device is supported but only exposes a single entity for Instantaneous measured power in Watts.

Describe the solution you’d like Support to be added for Energy monitoring in KWh and if possible battery level

Device signature - this can be acquired by removing the device from ZHA and pairing it again from the add devices screen. Be sure to add the entire content of the log panel after pairing the device to a code block below this line. { "node_descriptor": "NodeDescriptor(logical_type=<LogicalType.EndDevice: 2>, complex_descriptor_available=0, user_descriptor_available=0, reserved=0, aps_flags=0, frequency_band=<FrequencyBand.0: 0>, mac_capability_flags=<MACCapabilityFlags.0: 0>, manufacturer_code=0, maximum_buffer_size=0, maximum_incoming_transfer_size=0, server_mask=0, maximum_outgoing_transfer_size=0, descriptor_capability_field=<DescriptorCapability.0: 0>, *allocate_address=False, *is_alternate_pan_coordinator=False, *is_coordinator=False, *is_end_device=True, *is_full_function_device=False, *is_mains_powered=False, *is_receiver_on_when_idle=False, *is_router=False, *is_security_capable=False)", "endpoints": { "1": { "profile_id": 49353, "device_type": "0x0001", "in_clusters": [ "0x0002", "0x0003", "0x0005" ], "out_clusters": [ "0x0001" ] }, "2": { "profile_id": 260, "device_type": "0x0007", "in_clusters": [ "0x0000", "0x0003", "0x0702" ], "out_clusters": [ "0x000a" ] } }, "manufacturer": "Develco", "model": "ZHEMI101", "class": "zigpy.device.Device" }

Additional context zigbee2mqtt appears to support energy monitoring for this device already: https://www.zigbee2mqtt.io/devices/ZHEMI101.html https://github.com/Koenkk/zigbee2mqtt/issues/5960

Also the OEM manufacturer has documentation on their webpage. https://www.develcoproducts.com/products/meter-interfaces/external-meter-interface/

The device pairing and now both entities were created successful, however both sensors do not offer units. As the customizing menu was removed, its not even easy to add correct units. Is that something that also needs to be added in ha core? The device_class is correct

@KieranDrain I think that best would actually be not to close this until you fixed any now known multiplication errors via a new quirk.
