Garbage pickup dates in Denmark: RenoWeb

Many municipalities in Denmark are using the same IT infrastructure for managing containers, routes, collection dates etc. This is a short tutorial for integrating with RenoWeb, so your home automation will keep track of the next pickup dates for your garbage containers.

Prerequisites: HTTP binding and JSONPath transformation.

To keep the solution itself simple, there is some preparation needed: You need to find your container ids.

First, get municipalities:

Next, find your street:

Now, find your address:

Last, get your pickup data:

In the response you will find your container ids. For example:

    "status": {
        "id": 0,
        "status": null,
        "msg": "Ok"
    "list": [
            "id": 1,
            "name": "140L haveaffald",
            "count": "1",
            "module": {
                "id": 2,
                "name": "Haveaffald 140 L",
                "fractionname": "Haveaffald"
            "fractionid": 7,
            "nextpickupdate": "Tirsdag d. 20-02-2024",
            "nextpickupdatetimestamp": "1708387200",

Here the id is 1 for the first container.

Now the most important part is done, since we have a working URL for retrieving the data we need. We can now configure some channels and items:

Thing http:url:renoweb "RenoWeb" [ baseURL=">
        Type string : next-pickup-garden-waste "Haveaffald" [ stateTransformation="JSONPATH:$.list[?( == 1)].nextpickupdatetimestamp" ]
        Type string : next-pickup-recycling    "Genbrug"    [ stateTransformation="JSONPATH:$.list[?( == 2)].nextpickupdatetimestamp" ]
        Type string : next-pickup-mixed-waste  "Restaffald" [ stateTransformation="JSONPATH:$.list[?( == 3)].nextpickupdatetimestamp" ]

And items:

Group:DateTime:EARLIEST RenoWeb_NextPickup "Næste tømning [%1$td.%1tm.%1$tY]" <time>

DateTime RenoWeb_NextPickup_GardenWaste "Haveaffald [%1$td.%1tm.%1$tY]" <time> (RenoWeb_NextPickup) { channel="http:url:renoweb:next-pickup-garden-waste" }
DateTime RenoWeb_NextPickup_Recycling   "Genbrug [%1$td.%1tm.%1$tY]"    <time> (RenoWeb_NextPickup) { channel="http:url:renoweb:next-pickup-recycling" }
DateTime RenoWeb_NextPickup_MixedWaste  "Restaffald [%1$td.%1tm.%1$tY]" <time> (RenoWeb_NextPickup) { channel="http:url:renoweb:next-pickup-mixed-waste" }

This mapping “magically” works because there is a DateTimeType constructor taking a string with an epoch value.

That’s it, really. Sitemap example:

Or widget Garbage Collection:


component: widget:garbage_list_v1
  datearray: '"Haveaffald","green","f7:trash","RenoWeb_NextPickup_GardenWaste"|"Genbrug","blue","f7:trash","RenoWeb_NextPickup_Recycling"|"Restaffald","black","f7:trash","RenoWeb_NextPickup_MixedWaste"'
  tomorrow: I morgen
  today: I dag

Next step is to use your imagination how to use this data. As an example, I’m using a Sonos Move 2 as audio sink with prepared TTS audio samples for announcing upcoming pickups after a certain time of the day when motion is detected in the family room (i.e. when there is someone there to hear the announcement).

Have fun!
