Digital Filter for Devices/Variables

Works like a charm now! Thanks!!

That’s great! Thank you for the feedback.

Just tried to make some filters to use for my esp8266 nodes, implemented as VariablesDevices. But the filter does not like the devices as they lack getTemperature() and getHumidity(). Is this a limitation, or am i just doing it wrong?

  "devices": [
    {
      "id": "esp01",
      "name": "Bedroom Temp/esp",
      "class": "VariablesDevice",
      "variables": [
        {
          "name": "Temperature",
          "expression": "$esp01-tem",
          "type": "number",
          "unit": "°C"
        },
        {
          "name": "Humidity",
          "expression": "$esp01-hum",
          "type": "number",
          "unit": "%"
        },
        {
          "name": "Uptime",
          "expression": "$esp01-upt",
          "type": "number"
        }
      ]
    },
    {
      "class": "SimpleMovingAverageFilter",
      "id": "esp01-filter",
      "name": "Bedroom Temp/esp-Filter1",
      "size": 5,
      "output": {
            "name": "humidity",
            "label": "Humidity",
            "expression": "$esp01-hum",
            "acronym": "H",
            "type": "number",
            "unit": "%"
      }
    },
    {
      "class": "SimpleMovingAverageFilter",
      "id": "esp01-filter2",
      "name": "Bedroom Temp/esp-Filter2",
      "size": 5,
      "output": {
            "name": "temperature",
            "label": "Temperature",
            "expression": "$esp01-tem",
            "acronym": "T",
            "type": "number",
            "unit": "°C"
      }
    }
....
  "variables": [
    {
      "name": "esp01-hum",
      "value": 95
    },
    {
      "name": "esp01-upt",
      "value": 1834
    },
    {
      "name": "esp01-tem",
      "value": 17
    },

and the associated log output:

21:14:58.843 [pimatic] info: New device "Bedroom Temp/esp-Filter1"...
21:14:58.862 [pimatic] error: Error loading device esp01-filter: Method getTemperature of Bedroom Temp/esp-Filter1 does not exist!

@beikeland

change your expression to $device.attribute so maybe this expression will work $esp01-tem.value

Didn’t seem to have any effect. Although, I’ve “cheated” and implemented a filter in the ESP8266 sensor node.
