UI

v3.2 in win11:

Support DMM Models

Type:	Models			Test
1. Multimeter (1):	Aneng 9002	BSIDE ZT-300AB	ZOYI ZT-300AB	Yes
2. Small-Multimeter (2):	Aneng V05B	BSIDE ZT-5B	ZOYI ZT-5B	Yes

4. Desk-Multimeter (4):	Aneng AN999S		ZOYI ZT-5566S	Not completely

Just tested with ZOYI ZT-300AB. This solution is very cheap, I just bought a new one by ~ 100 RMB (~ 10 + USD).

This is the cheapest with capability to connect with Mobile Phone or Computer. They officially provide Mobile Phone version. So I just open this project for fun.

Development

Requirements

Python 3.8
pyside6 pyqtgraph qt_material bleak
pyinstaller (nuitka not recommend because of seriously memory leak problem)
If using Linux, need BlueZ >= 5.43 (additionally required by bleak)
Whether using conda (or other virtual env management) or not, it's recommended to use 'pip install' to install all packages listed in requirements.txt.
Run:

python main.py

The way to pack for Windows:

Environment：

First install the pyinstaller:
pip install pyinstaller

Pack (Scripts for Windows)

See the files in releases fold for detail.

PyInstaller

Enter your enviroonment (Virtual recommand) -> Install all packages needed -> Run the file: "/Releases/Win64/1.pyinstaller.bat".
Note: All the resource files are included in ./Ui/resources.qrc.

Advanced Installer

Then, for Windows, you can run directly or pack it with NSIS or other pack programs such as advanced installer.
For example, using "BLE DMM Client.aip" in "/Releases/Win64/Advanced_Install".

Zip for Releases

Run "/Releases/Win64/3.Copy_and _Compress.bat".

Known issues

Memory leak

Packing by Nuitka will cause a serious memory leak problem, so PyInstaller is recommended.

Compiled file may get the error below:

File "C:\MAIN~1.DIS\pyqtgraph\graphicsItems\ButtonItem.py", line 19, in __init__
ZeroDivisionError: float division by zero

They just fix this bug in 2022.04, if you use old version, please fix it manually, change line 18 of ButtonItem.py in your env: if width is not None: to if width is not None and self.pixmap.width():
Cross-platform ability in theory, but not tested yet.

qt_material issue

qt_material's dark theme have some issues with pyside6. Current version (2.14) not fixed yet, so manually add part of stylesheet in main.py.

self.apply_stylesheet(self, theme='dark_lightgreen.xml', extra=extra)
tooltip_stylesheet = """
    QToolTip {
        background-color: black;
    }
    QComboBox {
        color: white;
    }
"""
self.setStyleSheet(self.styleSheet()+tooltip_stylesheet)
