ZHA patch for more precision display of data for all Zigbee devices.

[pvvx]

ZHA patch for more precision display of data for all Zigbee devices.

Find the file components/zha/sensor.py (base path ~/.lib64/python3.xx/site-packages/homeassistant) and fix it:

class Sensor(ZhaEntity, SensorEntity):
    """Base ZHA sensor."""

    _attribute_name: int | str | None = None
    _decimals: int = 2
    _divisor: int = 1
    _multiplier: int | float = 1

        """Return the state of the entity."""
        # per zcl specs battery percent is reported at 200% ¯\_(ツ)_/¯
        if not isinstance(value, numbers.Number) or value == -1:
            return None
        value = round(value / 2, 1)
        return value

site-packages/homeassistant/components/zha/core/cluster_handlers/general.py :

class DeviceTemperature(ClusterHandler):
    """Device Temperature cluster handler."""

    REPORT_CONFIG = (
        {
            "attr": "current_temperature",
            "config": (REPORT_CONFIG_MIN_INT, REPORT_CONFIG_MAX_INT, 10),
        },
    )

            attr="measured_value",
            config=(REPORT_CONFIG_MIN_INT, REPORT_CONFIG_MAX_INT, 50),
        ),
    )

...

        ),
    )
