Help with state label based on sensor value

1

For the life of me I cannot figure out why this isn’t working. I just need a different set of eyes on it. I’m trying to change the color of a state label based on the battery level of my vacuum. I made a sensor in my config:

  - platform: template
    sensors:
      vac_batt:
        friendly_name: 'Roborock Battery'
        value_template: "{{ state_attr('vacuum.roborock_s7_maxv', 'battery_level') | int }}"

and I’m using it in my card as follows:

 card_mod:
      style: |
        :host { 
          color: {% if is_state('sensor.vac_batt') > 75 %} green {% elif is_state('sensor.vac_batt') > 30 %} yellow {% else %} red {% endif %};
        }

The sensor I made for changing the color of the state label for the activity works fine, but this one just won’t. Any thoughts?

Try to use states('sensor.vac_batt') instead of is_state.

is_state requires 2 arguments, the first one should be the entity_id and the second one should be the value to compare to, but that is an equal comparison, while you are trying a higher than, so probably in your case the states will work better, or even the state_attrib, as in this last case you don’t need that template sensor.

Nope. Still no color change.

Ok, I don’t know if that way of setting color work on that card.

What if you try this (I would expect the state always on red):

card_mod:
      style: |
        :host { 
          color: red;
        }

Does that works?
I’m just trying to verify the color attribute first before looking in the if/then/else.

No, that works because I did it the exact same way with the status of the vac. There is something wrong with the way it’s testing the sensor values. I can test in Node Red and tell that the value is a number so I’m not sure what’s wrong.

One more step isolating things to find the issue:

card_mod:
      style: |
        :host { 
          color: {% if 100 > 75 %} green {% elif 100 > 30 %} yellow {% else %} red {% endif %};
        }

It should become green now.

7

Yes. That works fine. It’s the comparison of the sensor values that’s breaking it.

What about this one? Which color you get and which color you expected?

card_mod:
      style: |
        :host { 
          color: {% if states('sensor.vac_batt') | float(0) > 75 %} green {% elif states('sensor.vac_batt') | float(0) > 30 %} yellow {% else %} red {% endif %};
        }

That worked! It bothers me that I don’t know why though. Thanks.

Probably the sensor is returning a string, then you are comparing to a number. By using the float(0) it forces the conversion to a number and will be 0 in case the string cannot be converted to a number.

This one might work also, without the need of that template sensor:

card_mod:
      style: |
        :host { 
          color: {% if state_attr('vacuum.roborock_s7_maxv', 'battery_level') | float(0) > 75 %} green {% elif state_attr('vacuum.roborock_s7_maxv', 'battery_level') | float(0) > 30 %} yellow {% else %} red {% endif %};
        }

And you probably wouldn’t have had this problem if you have created your vac_battery sensor using a device_class (and using the new format for template sensors):

template:
  - sensor:
    - name: Roborock Battery
      unique_id: vac_batt
      unit_of_measurement: '%'
      device_class: battery
      state: "{{ state_attr('vacuum.roborock_s7_maxv', 'battery_level') | float(0) | round(0) }}"
