 Configuration variables:
 ------------------------
 
 - **time_id** (*Optional*, :ref:`config-id`): Some Tuya devices support obtaining local time from ESPHome.
   Specify the ID of the :ref:`Time Component <time>` which will be used.
 
+- **status_pin** (*Optional*, :ref:`Pin Schema <config-pin_schema>`): Some Tuya devices support WiFi status reporting ONLY through gpio pin.
+  Specify the pin reported in the config dump or leave empty otherwise.
+  More about this `here <https://developer.tuya.com/en/docs/iot/tuya-cloud-universal-serial-port-access-protocol?id=K9hhi0xxtn9cb#title-6-Query%20working%20mode>`__.
+
 - **ignore_mcu_update_on_datapoints** (*Optional*, list): A list of datapoints to ignore MCU updates for.  Useful for certain broken/erratic hardware and debugging.
