MPK Łódź

Polish version: https://github.com/DominikWrobel/mpk_lodz/blob/main/PL.md

This is an integration to get live bus and tram departures using an unofficial MPK Łódź API. The code is based on the work of @PiotrMachowski

Install

• Install it with HACS by adding (https://github.com/DominikWrobel/mpk_lodz) as a custom repository

Usage

Find MPK Łódź in integrations page:

You can use stop_id, stop_number or group of stops, to get the stop info go to the page (http://rozklady.lodz.pl/) and find your stop, click on it and in the popup page you will see the number:

If it says busStopNum= use the number field, if it says busStopId= use the id field. To get the group stop number on the rozklady.lodz.pl page you have to check the Węzły przystankowe option and find your stop group:

Data

After the integration is set up you will get 10 entities, one for each departure from your stop, in the first entitie you will also get info on alert and the current time sent by the system

This data format is optimised for use by the custom:flex-table-card and you can get this card:

      content: "{{ (state_attr("sensor.mpk_lodz_group_1_piotrkowska_centrum_0", "current_time")) }}";
    }

And for the allert you can use the markdown card:

Card yaml

type: markdown
content: >
  <center> {{ (state_attr("sensor.mpk_lodz_group_1_piotrkowska_centrum_0",
  "alert")) }} </center>

You can set up as many stops as you want the data will be fatched every 1 min. Be aware that bus and tram stops without a LED display will not show the allert status, you can set up another stop (like Piotrkowska Centrum) to get the allert info.
