Looks like boolean property, but instead you define some numbers. What are the values for these numbers? Why these are numbers not booleans? Second - what does it mean "enable"? We have a generic "status" property for it - isn't this the same? Third, all these properties (especially PoE) look like you keep describing here network device but this is HWMON part. > + items: > + minimum: 0 > + maximum: 1 > + > + power: > + description: Whether the port should be powered on > + items: > + minimum: 0 > + maximum: 1 > + > + poe_plus: No underscores in property names. > + description: Whether the port should support PoE+ > + items: > + minimum: 0 > + maximum: 1 > + Best regards, Krzysztof
