PXL_20231217_085203870.MP.mp4

Working principle

• Station retrieves sensor states from home assistant via http api (/api/states) every n-th second (defined in config-lock.json)
• List of home assistant entities required for the station to work is defined in devices section of config. For example, temp_outside contains the name of the sensor with outside temperature, prec_type contains numeric type of precipitation (0 - clear, 1 - rain, 2 - snow, 3 - snowy rain).
• List of widgets is defined in elements section of config. This list describes display order, color and alignment of elements. Widget types are hardcoded by name and linked internally with sensors from devices section.
• Home assistant auto-discovery is used to create controls and input for text.

todo

• merge devices and elements sections of config, make widgets list fully configurable, create widget types
