LocalTuya Version

No response

Home Assistant Version

2025.5.1

Environment

  • Does the device work using the Home Assistant Tuya Cloud component?
  • Is this device connected to another local integration, including Home Assistant and any other tools?
  • The devices are within the same HA subnet, and they get discovered automatically when I add them

What happened?

0 is interpreted as None, this is incorrect.

In sensor.py, in the function "def status_updated(self):" is the code:

if (sub_sensor := getattr(self, "_attr_sub_sensor", None)) and (
  sub_state := self.decode_base64(state).get(sub_sensor)
  ):
     self._state = sub_state
else:
     self._state = state"

The following code is better. Because if a sensor returns 0, it must not be interpreted as None.

sub_sensor = getattr(self, "_attr_sub_sensor", None)
decoded = self.decode_base64(state)

if sub_sensor is not None and sub_sensor is in decoded:
  self._state = decoded[sub_sensor]
else:
   self._state = state

Steps to reproduce.

Add a sensor with base64 - Value. And change the Value to 0.

0 doesn't interpreted as None; tho both of them interpreted as false values, when I made then I never thought about 0 being an actual value of power, voltage or current


This will works

e.g.


            if None not in (
                sub_sensor := getattr(self, "_attr_sub_sensor"),
                sub_state := self.decode_base64(state).get(sub_sensor),
            ):
                self._state = sub_state
            else:
                self._state = state


Thanks for noticing/reporting this :)
