ZHA patch for more precision display of data for all Zigbee devices. #6
Description
ZHA patch for more precision display of data for all Zigbee devices.
New version Home Assistant
Core: 2024.10.2
Frontend: 20241002.3
Accuracy of values according to the Zigbee standard:
Find the file zha/application/platforms/sensor/__init__.py (base path ~/lib64/python3.xx/site-packages/zha/application/platforms/sensor) and fix it _decimals: int = 1 to _decimals: int = 2:
class Sensor(PlatformEntity):
"""Base ZHA sensor."""
PLATFORM = Platform.SENSOR
_attribute_name: int | str | None = None
_decimals: int = 2
_divisor: int = 1
Battery percent - step 0.5%

return value
REPORT_CONFIG
Find the file zha/zigbee/cluster_handlers/measurement.py (base path ~/lib64/python3.xx/site-packages/zha/zigbee/cluster_handlers/measurement.py) and fix it REPORT_CONFIG step value:
