Butten used as Timer

---

Hey everyone,

I was wondering if it would be possible to create a button and log the time this button is switched on. In first place I planning to have a kind of time recording, but this might also be used to log running time of rf switches etc.

Best regards,
Anduril

You could try this.

IF every 1 ms and button xy is on THEN set $timer to $timer + 1

Create a timer device:

    {
      "resolution": 60,
      "xLink": "",
      "id": "daytimer",
      "name": "DayTimer",
      "class": "Timer"
    },

A resolution of 60 means you want to update every 60 seconds (think of your DB!).
You can start and stop the timer in rules, and use the count:

IF lamp is off THEN stop dayptimer
IF time of daytimer >= 300 THEN log "timer is 5 minutes!" and stop daytimer and reset daytimer

thanks for your suggestions. Is it possible to add the value to a dummybutton? Would be great to see the amount of tima accumulated.

@Anduril
you could try to use the variables device for displaying the value of the timer

Example from my config:

    {
      "variables": [
        {
          "name": "tijd",
          "expression": "$pumptimer.time",
          "type": "number",
          "unit": "s",
          "label": "",
          "discrete": false,
          "acronym": ""
        },
        {
          "name": "tijd-todo",
          "expression": "$PumpHoursToDo",
          "type": "number",
          "unit": "s",
          "label": "",
          "discrete": false,
          "acronym": ""
        },
        {
          "name": "tijd-left",
          "expression": "$PumpHoursToDo-$pumptimer.time",
          "type": "number",
          "unit": "s",
          "label": "",
          "discrete": false,
          "acronym": ""
        }
      ],
      "xLink": "",
      "id": "timer-display",
      "name": "gemaakte uren / uren te gaan / resterende uren",
      "class": "VariablesDevice"
    }

ok thanks a lot for all your help. I tried using a timer device and the rule according to p4co86.
Is there an option to manually edit the timer variable? And when displaying the time in a variable device I only get the number of seconds. Is it possible to display in a h:mm format?
Same for the rule option, I can count the minutes, but displaying it in h:mm format seems difficult. I can manually split (if minutes>60 then minuten=minutes-60 and hours=hours+1) but in a variable device I see the graph between to variables. Can I turn this graph off?

You could say, if variable = 60 then set hour.variable to 1 and min variable to 0 or if min.variable = 120 then set hour.variable to 2 and min.variable to 0
Than display both variables in one variables device.
Its untested. But you can try a little bit and it should work.

If you set the unit in S (like my example) the time will be automaticly converted in Hs format

the hint with the units was good, but not the finish line. Two problems: with unit s you also get seconds, which is not very nice as I only update the timer every 60s. Second I don’t know how to manipulate the timer value by hand.
But searching for suitable units lead me to the function formatNumber, which will convert a number to a string and therefor eliminate the log and graph. Only problem is that this assumes the value has a unit itself and sets B if not stated other. Can I somehow set it to be a pure number and give a unit by “unit” definition of the variable device?

{
  "class": "SystemSensor",
  "id": "db-size",
  "name": "Datenbankgröße",
  "attributes": [
    {
      "name": "dbsize",
      "interval": 3600000
    }
  ],
  "xAttributeOptions": [
    {
      "name": "dbsize",
      "displaySparkline": false
    }
  ]
},

With the xattribute displaysparkline you can disable the graph and the type can be still number.

Thank you @p4co86 , thats exactly what I wanted. Now it’s nearly perfect. Just 2 details, maybe you know how to solve them:

1. I have my time recording to track minutes and hours and show an average over a week. It looks just a litte funny when the average is given in X.XX minutes. Is it possible to round to full minutes?
2. Is it also possible to edit the sparkline? I think of an sparkline showing the average of the last weeks, but normal sparkline shows only for a shorter time (don’t know if it’s determined by number of datapoints or time).

first: you can round a variable like this $variable2 = round($variable1,2) were 2 means two decimal. but i dont no if it works for a timer.
second: i dont now, but i mean there is no option to edit the sparkline.

Thanks @p4co86 , that worked. I added it directly to my variable device. I don’t use a timer device but a variable that is counted up every minute by a rule as you suggested in your first post.
I will try a litte with the sparkline, in case of succes I will post here for others to read.
