@yutaka551 Can you please fill the PR template?

I can tell what it is because it integrates with my PlotlyTempGraph plugin (obviously copilot is involved). The functionality I can tell will work purely based on the programming logic, but there are issues with plugin:

• importing the library every time it goes to read the sensor here rather than just a simple import with the rest at top to initialize on load. the module is defined in plugin_requires so no need for the whole try/catch block for the ImportError here
• software update here return doesn't match plugin identifier defined here.
• missing plugin author email
• using old setup.py method rather than newer pyproject.toml used in current cookiecutter template
• not actually an issue, but version defined here and in setup.py, make sure to update both places in future updates or it will cause update loops.
• do you even need the AssetPlugin if you're not actually returning anything, this whole block could be removed and this line.
