THETA Plug-in sample that works with multiple "SwitchBot MeterTH"

• Acquires the temperature and humidity advertised by multiple SwitchBot thermo-hygrometers and displays them in a list on the WebUI (dynamic update)
• The humidity history of one thermo-hygrometer selected from the list is displayed as a graph on the WebUI (dynamic update).
• Take a picture triggered by a sudden rise in humidity of one thermo-hygrometer selected from the list (judgment is in THETA. WebUI is for visualization and is not essential)

This plugin is based on this plugin that displays the live preview on the WebUI, and adds BLE processing.
