Trying to create an icon_template of a mqtt sensor

TheStigh · February 13, 2020, 7:58pm

Hi,

Have a MQTT sensor with a value (in this case -99)

Tried this in dev-template and it works.

      {% set rssi_level = states("sensor.mate_30_pro_rssi_level")|float %}
      {% if rssi_level == -99 %}
        mdi:sim-off
      {% else %}
        {% if rssi_level >= -90 %}
          mdi:signal-cellular-outline
        {% elif rssi_level > -60 %}
          mdi:signal-cellular-1
        {% elif rssi_level > -30 %}
          mdi:signal-cellular-2
        {% else %}
          mdi:signal-cellular-3
        {% endif %}
      {% endif %}

Completed the sensor setup:

  - platform: mqtt
    name: Mate 30 Pro RSSI Level
    state_topic: "monitor/stue/monitor_stigh_mate30/rssi"
    icon_template: >-
      {% set rssi_level = states("sensor.mate_30_pro_rssi_level")|float %}
      {% if rssi_level == -99 %}
        mdi:sim-off
      {% else %}
        {% if rssi_level >= -90 %}
          mdi:signal-cellular-outline
        {% elif rssi_level > -60 %}
          mdi:signal-cellular-1
        {% elif rssi_level > -30 %}
          mdi:signal-cellular-2
        {% else %}
          mdi:signal-cellular-3
        {% endif %}
      {% endif %}

…then the entire sensor fails…

Can’t figure out what is wrong

chnage float to int. Other than that, it looks good. But… just looked at the docs and it looks like icon_template isn’t a valid field for mqtt sensors. So that’sprobably your problem.

jocnnor · February 13, 2020, 8:04pm

Was just about to hit the reply button saying the same thing as you…again.

@TheStigh Leave your MQTT sensor as is and create a template sensor if you want a template_icon. You can use the mqtt sensor for the majority of the template sensor fields.

petro · February 13, 2020, 8:04pm

Hah, I was just giving you shit the other day, don’t worry about it

TheStigh · February 13, 2020, 8:04pm

Hi @petro,

Of course it’s you answering first Happy you’re around!
Hummm… perhaps just make a new template sensor of this sensor then?

TheStigh · February 13, 2020, 8:05pm

Haha, was typing to petro when you replied … yeap, I will.

petro · February 13, 2020, 8:07pm

Actually, just change the device class to signal_strength

device_class: signal_strength

should change the icon without the need to create the template.

TheStigh · February 13, 2020, 8:18pm

@petro, supported by mqtt platform?

petro · February 13, 2020, 8:19pm

Yep, every sensor supports device_class

TheStigh · February 13, 2020, 8:20pm

  - platform: mqtt
    name: Value Mate 30 Pro RSSI Level
    device_class: signal_strength
    state_topic: "monitor/stue/monitor_stigh_mate30/rssi"

Testing - rebooting now

TheStigh · February 13, 2020, 8:46pm

Using device_class, give it full signal at -99

Will restart my monitor-service and see when it actually connects…

TheStigh · February 14, 2020, 12:55am

@petro, @jocnnor

It kind’a works, but the negative value might cause the issues…
I never get the signal bar to increase, whatever the value is.
I’ve also tried to re-arrange the order, having -90 at the top.

I’m also uncertain if I say >= -90 what is bigger? -80 or -100 ? In my mind -80 is bigger than -90…

Any ideas?

  - platform: template
    sensors:
      monitor_mate_30_pro_rssi_stue:
        friendly_name: Mate 30 Pro RSSI Stue
        unit_of_measurement: 'dBm'
        value_template: '{{ states("sensor.value_mate_30_pro_rssi_stue") }}' 
        icon_template: >-
          {% set rssi_level = states("sensor.value_mate_30_pro_rssi_stue") | int %}
          {% if rssi_level == -99 %}
            mdi:sim-off
          {% else %}
            {% if rssi_level >= -20 %}
              mdi:signal-cellular-3
            {% elif rssi_level >= -40 %}
              mdi:signal-cellular-2
            {% elif rssi_level >= -65 %}
              mdi:signal-cellular-1
            {% elif rssi_level <= -90 %}
              mdi:signal-cellular-outline
            {% else %}
            {% endif %}
          {% endif %}

jocnnor · February 14, 2020, 1:16am

You have a gap from -90 to -65 where the template will return nothing.

        icon_template: >-
          {% set rssi_level = states("sensor.value_mate_30_pro_rssi_stue") | int %}
          {% if rssi_level == -99 %}
            mdi:sim-off
          {% else %}
            {% if rssi_level >= -20 %}
              mdi:signal-cellular-3
            {% elif rssi_level >= -40 %}
              mdi:signal-cellular-2
            {% elif rssi_level >= -65 %}
              mdi:signal-cellular-1
            {% else %}
              mdi:signal-cellular-outline
            {% endif %}
          {% endif %}

TheStigh · February 14, 2020, 1:21am

Still, even if the signal are between -20 and -40 I never get other icon than mdi:signal-cellular-outline
Can it be that it doesn’t read correctly what’s inside the if’s ?

Can it be the negative value ?

jocnnor · February 14, 2020, 2:26am

I assume so…it all works fine in the template editor with negative values.

Try adding:

  entity_id: 
    - sensor.value_mate_30_pro_rssi_stue

I don’t know what to say. It all seems right to me…

TheStigh · February 14, 2020, 8:26pm

Resolved Thnx @jocnnor and @petro

One of the sensor consist of

  - platform: mqtt
    name: Value Mate 30 Pro RSSI Stue
    device_class: signal_strength
    state_topic: "monitor/stue/monitor_stigh_mate30/rssi"

  - platform: template
    sensors:
      monitor_mate_30_pro_rssi_stue:
        friendly_name: Mate 30 Pro RSSI Stue
        unit_of_measurement: 'dBm'
        value_template: '{{ states("sensor.value_mate_30_pro_rssi_stue") }}' 
        icon_template: >-
          {% set rssi_level = states("sensor.value_mate_30_pro_rssi_stue") | int %}
          {% if -1 > rssi_level > -30 %}
            mdi:signal-cellular-3
          {% elif -31 >= rssi_level > -50 %}
            mdi:signal-cellular-2
          {% elif -51 >= rssi_level > -70 %}
            mdi:signal-cellular-1
          {% elif -71 >= rssi_level > -98 %}
            mdi:signal-cellular-outline
          {% else %}
            mdi:signal-off
          {% endif %}

petro · February 14, 2020, 8:27pm

fyi according to most things I’ve read about RSSI, anything better than -50 is ‘the most bars’.

TheStigh · February 14, 2020, 8:30pm

Well, such short distances in this house, so I kind of wanted full bars on very high signal.

Next task will be to make a math calculation to find out what room you are in.
It is possible, theoretically to be connected to all monitors (4 pcs), so to have a sensor showing what room you actually are in should be a calculation.

jocnnor · February 14, 2020, 8:33pm

Triangulation using wifi access points…love it!

TheStigh · February 14, 2020, 8:48pm

Tried it ?
