Hey guys,
I tried to implement a garbage calendar in my openHAB 3 installation.
At some days they are picking up two kinds of garbage in my place (for example tomorrow):
I tried to use the iCalendar Binding, but it shows only the next entry (“Gelber Sack/…”). But I need all entries for the next day.
Any idea how to solve this problem?
Thank you 
Use a different binding. This one won’t do what you want. Unfortunately there may not be any that do.
I had the same issue and use a script to grab the info via the API of my ‘trash-company’. I have an item for every type of trash and these are updated through the script.
Or someone should create a binding for OH like this one: GitHub - pippyn/Home-Assistant-Sensor-Afvalbeheer: Provides Home Assistant sensors for multiple Dutch and Belgium waste collectors 
Hi,
Just use switch items as proxy.
I have an Item for each kind of garbage. In my calendar event, I switch the specific item to on with the BEGIN statement.
For example, our trash gets collected on Monday - my calendar event starts Sunday morning and ends on Monday. When it begins on Sunday, it will switch my trash reminder item to on. This works for as many calendar entries as you want!
Hi
You could create an eventfilter thing for each garbage type.
Than you will have multiple items which will store the next date of the garbage pickup of the configured garbage type
Hey guys,
thank you for your answers.
I created a php script, to extract the necessary dates and save them into items.
Why PHP? I’m better using PHP than shell script or python 
Maybe it is helpful for someone, here is my script:
<?php
$ics = ""; // url to the calendar file
$filename = "Abfallkalender.ics";
$max_age = 3600;
require("class.ical.php");
if (!file_exists($filename)) {
if (!file_put_contents($filename, file_get_contents($ics)) ) {
die("Beim Download ist ein Fehler aufgetreten");
}
}
else {
$filemtime = filemtime($filename);
if (time() >= ($filemtime + $max_age)) {
// Datei zu alt - lade erneut herunter
if (!file_put_contents($filename, file_get_contents($ics)) ) {
die("Beim Download ist ein Fehler aufgetreten");
}
}
}
$ical = new iCal($filename);
$eventsByDate = $ical->eventsByDate();
$eventsByDateSince = $ical->eventsByDateSince(time());
$array = array();
$count_gelber_sack = 0;
$count_papier = 0;
$count_bio_restmuell = 0;
foreach($eventsByDateSince as $key => $value) {
foreach ($value as $key2 => $value2) {
if ($value2->summary == "Gelber Sack/Gelbe Tonne") {
if ($count_gelber_sack == 0) {
$array['next_gelber_sack'] = $key;
$count_gelber_sack++;
}
else if ($count_gelber_sack == 1) {
$array['next_but_one_gelber_sack'] = $key;
$count_gelber_sack++;
}
}
else {
if ($value2->summary == "Papiertonne") {
if ($count_papier == 0) {
$array['next_papier'] = $key;
$count_papier++;
}
else if ($count_papier == 1) {
$array['next_but_one_papier'] = $key;
$count_papier++;
}
}
else {
if ($value2->summary == "Restabfall/Bioabfall") {
if ($count_bio_restmuell == 0) {
$array['next_bio_restmuell'] = $key;
$count_bio_restmuell++;
}
else {
$array['next_but_one_bio_restmuell'] = $key;
$count_bio_restmuell++;
}
}
}
}
}
}
if ($argc > 1) {
$param = trim($argv[1]);
if (array_key_exists($param, $array)) {
echo $array[$param];
}
else {
die("Falscher Parameter");
}
}
else {
die("Kein Parameter");
}
?>
For reading the ical file I’m using this php class: iCal PHP Parser · GitHub
These are my items:
String Muellkalender_next_papier "Nächste Leerung Papiertonne"
String Muellkalender_next_but_one_papier "Übernächste Leerung Papiertonne "
String Muellkalender_next_gelber_sack "Nächste Leerung Gelber Sack"
String Muellkalender_next_but_one_gelber_sack "Übernächste Leerung Gelber Sack"
String Muellkalender_next_bio_restmuell "Nächste Leerung Restabfall/Bioabfall"
String Muellkalender_next_but_one_bio_restmuell "Übernächste Leerung Restabfall/Bioabfall"
This is the rule to actualize the items:
rule "Müllkalender"
when
Time cron "0 0 * ? * * *"
then
// Bio/ Restmüll
var String next_papier = executeCommandLine(Duration.ofSeconds(10), "/usr/bin/php", "/etc/openhab/scripts/muellkalender/garbage.php", "next_papier2")

While I’m writing this, I see there could be a much better way to write the rule
