[Solved] Newcomer problems with pimatic-filter plugin

---

I just started to use pimatic-filter plugin and have several problems. My first filter looks like this:

{
  "stats": [
    "min",
    "max",
    "mean",
    "source"
  ],
  "output": {
    "name": "temperature",
    "expression": "$ESP02.temp"
  },
  "xAttributeOptions": [
    {
      "name": "min",
      "displaySparkline": false
    },
    {
      "name": "max",
      "displaySparkline": false
    },
    {
      "name": "mean",
      "displaySparkline": false
    },
    {
      "name": "source",
      "displaySparkline": false
    },
    {
      "name": "temperature",
      "displaySparkline": false
    }
  ],
  "id": "esp02tempfiltered",
  "name": "ESP02TempFiltered",
  "class": "SimpleTruncatedMeanFilter"
}

Firstly the filtered temperature does not appear in the variables list of the UI (Whereas all stats attributes are present, like $esptempfiltered.min, $esptempfiltered.source etc.)

Secondly the filtered temperature can not be referred in rules.

Further it is named with leading $ ($temperature and not temperature) on the graph page.

Works for me.

Yes, that’s strange and it might be a bug. I’ll have a look into this

@mwittig Thanks. I tried it again and after some refreshing and restarting (can not reconstruct in detail) the temperature attribute appears in variables list as well as in rules.

How can I reset the stats attributes without recreating the filter device?

You can call the resetStats device action, e.g.

GET http://<HOST>/api/device/filter-1/resetStats

However, note, the display of the filter device does not update, but the variables do. I am going to fix that with the next release.

Apparently, this happens if no “label” is set. I am going to fix this with the next release, by setting a suitable default. You can work-around this by setting the label for the output, e.g. set the label to “temperature”.

EDIT: Caused by a typo in the code. The work-around applies.

Thanks for the hint. Would be more natural if a rule construct would exist like

When ... then reset filter-1

Agree. I haven’t implemented this yet due to laziness,

@Heizelmann, voilà pimatic-filter@0.9.2
* added reset action provider
* fixed filter default output attribute label
* fixed resetStats did not update display
* excluded ‘src’ attribute from reset

If you like this plugin, please consider ★ starring the project on github.

@mwittig Thanks a lot. I tested it quickly and found that src is not excluded from reset but the filter output. Further the stats values min, max, mean are set to 0. I have a long update interval and if I reset the filter, it might happen that for a long time alk stats values are 0. When an update happens all values are OK. A reset in my opinion should set min, max and mean to the last src.

Some polishing for the graph page: The labels for min, max, mean starts with uppercase letter, the filter output variable as it is named. All attributes are defined lower case.

@mwittig thanks for the quick update. The reset function works as expected now. But when creating/recreating filter device the min value is set to zero even the source value is different.

Further the default value of displaySparline is displayed as false but sparkline is showed.
