ZHA Toolkit - unable to read or write

Hello fellow Home Assisters

Don’t know why, I have a stubborn zigbee window cover that resets its opening time to the default 600 when I want 250.

I was hoping to get some help in order to read and write attributes in order to setup a automation that enforces the time of a 100% open blind.

My device signature is this

{
  "node_descriptor": {
    "logical_type": 1,
    "complex_descriptor_available": 0,
    "user_descriptor_available": 0,
    "reserved": 0,
    "aps_flags": 0,
    "frequency_band": 8,
    "mac_capability_flags": 142,

    "maximum_incoming_transfer_size": 66,
    "server_mask": 10752,
    "maximum_outgoing_transfer_size": 66,
    "descriptor_capability_field": 0
  },

        "0x0102"
      ],
      "output_clusters": [
        "0x000a",
        "0x0019"
      ]
    },

        "0x0021"
      ]
    }
  },
  "manufacturer": "_TZ3210_ol1uhvza",
  "model": "TS130F",
  "class": "ts130f.TuyaTS130FTOGP"
}

Using Developer Mode, I was trying this:

Basically, What I want to achieve is this:

Any help or pointer of what can I be doing wrong?
