Help with building a quirk for PTVO firmware - DHT22 Temperature Humidity

Configuration Zigbee
1

I connected a DHT22 sensor to a CC2530+CC2591 module flashed with the PTVO firmware, but I can only see the temp and humidity values beeing reported in log files but no entities showing up in HA.

My understanding is that I need to create a so called quirk in order to translate these values into someting that HA can understand.
Is there any example that I can look at ?
I have already gone through the zha-device-handlers section on github with no luck.
Any idea/guidance is welcome.

First step is to show the device, e.g:

image
image1342×851 62 KB

Then paste its signature, e.g.

{
  "node_descriptor": "NodeDescriptor(byte1=2, byte2=64, mac_capability_flags=128, manufacturer_code=4107, maximum_buffer_size=89, maximum_incoming_transfer_size=63, server_mask=0, maximum_outgoing_transfer_size=63, descriptor_capability_field=0, *allocate_address=True, *complex_descriptor_available=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, *is_valid=True, *logical_type=<LogicalType.EndDevice: 2>, *user_descriptor_available=False)",
  "endpoints": {
    "1": {
      "profile_id": 49246,
      "device_type": "0x0830",
      "in_clusters": [
        "0x0000"
      ],
      "out_clusters": [
        "0x0000",
        "0x0003",
        "0x0004",
        "0x0005",
        "0x0006",
        "0x0008"
      ]
    },
    "2": {
      "profile_id": 260,
      "device_type": "0x000c",
      "in_clusters": [

        "0x000f",
        "0xfc00"
      ],
      "out_clusters": [
        "0x0019"
      ]
    }
  },

Not that simple unfortunately

If you mean by that “Is creating a zha quirk simple?”, no, definitely not.
