RMV - When do I need to go?

Introduction

See the time remaining until you have to leave to catch the next ride. I often have to catch a train or bus and I want to know when I have to leave to catch it.

Prerequisites

Home Assistant instance
(optional) standalone sensors.yaml

Configuration

Needed Information

Name	Description	Where to find
Station ID	The ID of the station you want to get the next departure from.	RMV (Infrastrukturdaten) - Search Document for your station and take the ID
Time Offset	The time offset in minutes you need to get to the station.	GoogleMaps/RMVGo or just from experience
Direction	The direction you want to go.	RMV (Infrastrukturdaten) - Search Document for your destination station and take the NAME
Station Name	The name of the station you want to get the next departure from. Choose what you want. Recommend name of station

Sensor

YAML
# sensors.yaml
- platform: rmvtransport
  next_departure:
    - station: [Station ID]
      time_offset: [Time Offset]
      direction: [Direction]
    - station: [Station ID]
      name: [Station Name] All
      direction: [Direction]

Restart

After adding the sensor to your configuration, restart Home Assistant. You should now have a sensor for all the departures from the station and a sensor for the next departures from the station you can reach.

Helper

To get the sensor for the time you need to leave, you have to create a template sensor. This sensor will calculate the time you have to leave to catch the next ride. Go to Settings -> Devices & Services -> Helpers -> Add Helper -> Template -> Create template for a sensor

Give it a name and use the following template:

{{ (int(states('sensor.[Station Name without all]'))) - 7 }}

Set the unit to minutes and save it.

Lovelace

I use the following Lovelace card to display the time I have to leave to catch the next ride.

YAML
type: gauge
entity: sensor.[Helper Sensor Name]
needle: false
min: 0
max: 15
severity:
  green: 3
  yellow: 7
  red: 10

Tweak the values to your needs.

Time Table Card

There is also a custom card in HACS to display the next departures from a station. It is called RMV Card and can be found in HACS (Frontend). After installing it you can use the following code to display the next departures from a station:

YAML
type: custom:rmv-card
entity:
  - sensor.[Station Name with all]
