Cant get YAML and LAMDA working

deanfourie · September 1, 2023, 9:22am

Can anyone help me with this, i’ve tried this in so many variations and it just will not work? Gives me formatting errors.

Thanks

      float w1 = id(y);
      w0 = min(max(w0 * 2.0 - 1.0, -1.0), 1.0);
      w1 = min(max(w1 * 2.0 - 1.0, -1.0), 1.0);
      float w = atan2(w0, w1);
      w = 360.0 * w / (2.0 * M_PI) + 180.0;
      if ( w >= 360.0 ) w -= 360.0;
      if ( w < 0 ) w = 0;
      return w;

Maybe post the errors it gives you? There is probably a clue in there.

Where are these defined? Not in the yaml you have posted.

Apologies - I didn’t drop enough hints. When you’ve been a IT team lead for 30 years you try and make the guys work it out. Try:

####Wind Direction Start####
  - platform: mlx90393
    id: mlx
    x_axis:
      name: "mlx_x"
      id: "x"
    y_axis:
      name: "mlx_y"
      id: "y"
    z_axis:
      name: "mlx_z"
    update_interval: 1s

  - platform: template
    id: 'wind_direction'
    name: 'Wind Direction'
    update_interval: 5s
    lambda: |-
      float w0 = id(x);
      float w1 = id(y);
      w0 = min(max(w0 * 2.0 - 1.0, -1.0), 1.0);
      w1 = min(max(w1 * 2.0 - 1.0, -1.0), 1.0);
      float w = atan2(w0, w1);
      w = 360.0 * w / (2.0 * M_PI) + 180.0;
      if ( w >= 360.0 ) w -= 360.0;
      if ( w < 0 ) w = 0;
      return w;
####END Wind Direction####

Note the addition of the id: in the sensor definition. In the docs:

x_axis (Optional): The information for the x-axis.

name (Required, string): The name for the x-axis sensor.

id (Optional, ID): Set the ID of this sensor for use in lambdas.

EDIT: Also apologies for being a smartass. I just announced my retirement at the end of this year so I’m feeling a bit smug.

deanfourie · September 1, 2023, 11:32am

Its working,

Sorry, what did you change just so i know

Added the Id: lines - so that the ids you were referencing in lambda existed.

zoogara · September 1, 2023, 11:39am

Try float w1 = atof(id(y));

They are probably string arrays and you need to force conversion.

deanfourie · September 1, 2023, 11:42am

Ah - ok - it’s coming back to me now…

Try this - sensors are their own type, so this might work:

  - platform: template
    id: 'wind_direction'
    name: 'Wind Direction'
    update_interval: 5s
    lambda: |-
      float w0 = atof(id(x).state.c_str());
      float w1 = atof(id(y).state.c_str());
      w0 = min(max(w0 * 2.0 - 1.0, -1.0), 1.0);
      w1 = min(max(w1 * 2.0 - 1.0, -1.0), 1.0);
      float w = atan2(w0, w1);
      w = 360.0 * w / (2.0 * M_PI) + 180.0;
      if ( w >= 360.0 ) w -= 360.0;
      if ( w < 0 ) w = 0;
      return w;

lol! I’m having a sugar fix but not helping the brain. So you were right in the first instance - they are probably already float, but you were referencing the sensor, not the value of the sensor…

Try this:

  - platform: template
    id: 'wind_direction'
    name: 'Wind Direction'
    update_interval: 5s
    lambda: |-
      float w0 = id(x).state;
      float w1 = id(y).state;
      w0 = min(max(w0 * 2.0 - 1.0, -1.0), 1.0);
      w1 = min(max(w1 * 2.0 - 1.0, -1.0), 1.0);
      float w = atan2(w0, w1);
      w = 360.0 * w / (2.0 * M_PI) + 180.0;
      if ( w >= 360.0 ) w -= 360.0;
      if ( w < 0 ) w = 0;
      return w;

Thank you so much that worked.

Ill test it for calibration.

deanfourie · September 1, 2023, 12:17pm

I know this is asking a lot, but is there a way to have it report N, SW, S, SW etc.?

zoogara · September 1, 2023, 12:23pm

Ah - so that I have, but unfortunately I do it in HA:

  - platform: template
    sensors:
        named_wind_direction:
          friendly_name: 'Wind Ordinal'
          value_template: >-
            {%if states.sensor.wind_direction.state | float<=11 %}N
            {% elif states.sensor.wind_direction.state | float>348 %}N
            {% elif states.sensor.wind_direction.state | float<=34 | float>11 %}NNE
            {% elif states.sensor.wind_direction.state | float<=56 | float>34 %}NE
            {% elif states.sensor.wind_direction.state | float<=79 | float>56 %}ENE
            {% elif states.sensor.wind_direction.state | float<=101 | float>79 %}E
            {% elif states.sensor.wind_direction.state | float<=124 | float>101 %}ESE
            {% elif states.sensor.wind_direction.state | float<=146 | float>124 %}SE
            {% elif states.sensor.wind_direction.state | float<=169 | float>146 %}SSE
            {% elif states.sensor.wind_direction.state | float<=191 | float>169 %}S
            {% elif states.sensor.wind_direction.state | float<=214 | float>191 %}SSW
            {% elif states.sensor.wind_direction.state | float<=236 | float>214 %}SW
            {% elif states.sensor.wind_direction.state | float<=259 | float>236 %}WSW
            {% elif states.sensor.wind_direction.state | float<=281 | float>259 %}W
            {% elif states.sensor.wind_direction.state | float<=304 | float>281 %}WNW
            {% elif states.sensor.wind_direction.state | float<=326 | float>304 %}NW
            {% elif states.sensor.wind_direction.state | float<=348 | float>326 %}NNW
            {%- endif %}

So 135 is SE.

You could convert the jinja code to lambda I reckon. If you get stuck then there’s always tomorrow.

deanfourie · September 1, 2023, 12:28pm

I think that could work. Thanks.

Let me do more testing.

Thanks for your help

One quick question regarding the rain gauge, im getting measurements that are about 10ml off.

So im testing my rain gauge using unit_of_measurement: ml and then pouring like 150ml of water in, its reporting 160ml.

Is this a problem, its 10ml out, is this to be expected to not get perfect measurements?

Thanks
