Read values from plant domain

[k1rd3rf]

It would be nice to specify one entity instead of each and every entity, since HA support the plant domain.

plant:
  ficus:
    sensors:
      moisture: sensor.plant_ficus_moisture
      conductivity: sensor.plant_ficus_conductivity
      brightness: sensor.plant_ficus_brightness
      temperature: sensor.plant_ficus_temperature
      battery: sensor.plant_ficus_battery
    min_moisture: 20
    max_moisture: 60
    min_conductivity: 350
    max_conductivity: 2000
    min_brightness: 2500
    max_brightness: 35000
    min_temperature: 8
    max_temperature: 32
    min_battery: 15

  plant: plant.ficus

I like the idea.
Getting the current status from the plant entity is easy enough. However, I can't find an easy way to get the configured max/min-values.
There is another card here that just checks if the state contains a keyword, and will color the icon red based on that:

But I don't really like that approach.

I think it would be better to get the configured min/max-values into the attributes of the plant "sensors":
https://github.com/home-assistant/core/blob/dev/homeassistant/components/plant/__init__.py

That way we could read it directly from the plant entity.
But that requires a PR to the plant component...
