Daily and Storm Rain Totals

[kaijk]

We've had quite some rain the last few days so my Rain Chart shows some interesting data.

My Ecowitt rain gauge provides Daily, Hourly, and Event duration values. The columns are the daily intra-day totals that reset each day, Cumulative is the time progression and aonther view of the daily sensor, while the interval are the individual hourly readings. The storm total sensor resets itself to zero after some hours of no rain.

New sensor, new charts!
Thanks for sharing

Hello all,

I am trying to get this graph to work. I am having and issue with the blue bar graph. I know this works fine because I can pull the value from the HA web integration and it works fine. Here is my issue. Im pulling data for a Davis Vantage Vue from WeeWX via MQTT. I get the value into HA fine and in the yaml I make sure the value is a float. The sensor value I create is basically a value of .01 inch each time the cup tips. In order for me to get the total I created

• data_template:
  entity_id: input_number.weather_davis_daily_rain_inch
  value: >
  {{ states('input_number.weather_davis_daily_rain_inch') | float
  + 0.01 }}
  action: input_number.set_value
  I basically add the cup value to each tip. This works fine. Graphs fine in HA history. When I try to use it here:
  entities:
  - entity: sensor.gw2000b_daily_rain_rate
  time_offset: 12h
  showlegend: true
  type: bar
  width: 82500000
  statistic: state
  period: day
  name: Day
  unit_of_measurement: in
  The bar wont read. I feel like it is a formatting issue in the helper/sensor. I tried creating a sensor that calls the input_number and still nothing. Any help would be appreciated. I'm convinced Plotly doesn't like my data for some reason

Using WeatherLink Live

“somehow you get a lifetime increasing value for the cumulative bucket“. Can I use the input_number. Helper there to total the values?

[kaijk]

OK, Looks like you already found from the Davis Integration's developer's answer to your question in the repository that the Davis integration I mentioned won't work for your Davis. So, it's "roll your own." This will be fun, but well upstream of Plotly.

Open a discussion in the HA Community Forum and tag me and we'll take it off line from here. (I'd say no to input_number helpers in this case. You will want a bunch of weather sensors from your Davis. That "won't-work" integration showed 51....

[yestrdave]

Let me see what I can do with what you provided. I have all this working. I have all the sensors in HA via MQTT. I am just struggling with the format of this stupid rain sensor. Once I get it in the correct format. All will work. I’m in the home stretch.

[yestrdave]

I love the graph layout. Here is a working version using the HA Davis WeatherLink integration. Once I figure out this last MQTT sensor I will be in good shape. I will set up using all my local data.

[kaijk]

Looks like Helene missed you, thank goodness!

[yestrdave]

I was expecting more rain for sure.

[yestrdave]

@kaijk another question. If the sensor is showing a history graph in HA doesn’t that mean it’s in recorder?

[kaijk]

I have no idea how helpers are "recorded."

You want a sensor with state_class, device_class, and UOM when you want other than Now data. I've never seen a helper in a chart. Find a way to use a sensor. Template sensors are your friends.

[yestrdave]

@kaijk I have given this a go and need a little help. https://community.home-assistant.io/t/mqtt-rain-fall-total/776838

FYI the sensor setup :

• "tfa dostmann rain gauge" reports cumulative rain in mm
• OpenMQTTGateway RF 433MHz variant. To receive data and forward to mqtt.
