[CAP] Login to CF using a bash script

April 25, 2022 September 6, 2024

Create your script file, make it executeable and add it to your .gitignore as it contains sensitive information:

touch login.sh
chmod +x login.sh
echo login.sh >> .gitignore

Open the file and paste the following:

#! /bin/bash
cf login <<!
myemail@mail.com
mypassword
1 
!

With “1” you select your target space. Save your script and run it using:

./login.sh

After some time, it can happen that the default identity provider of the SAP BTP (SAP ID service) is asking for a password change. I don’t know exactly, but it seems to be every 90 days?!
The login process will fail with the following output:

$ ./scripts/login.sh
API endpoint: https://api.cf.eu10.hana.ondemand.com

Email: myemail@mail.com
Password: 

Authenticating...
{"error":"invalid_grant","error_description":"User authentication failed: PASSWORD_CHANGE_REQUIRED"}

To change your password, just go to https://account.sap.com or https://accounts.sap.com/, and it should directly open the password change screen.

Update 06.09.2024: The login can now also be done by completely using the cf command.

cf login -a https://api.cf.eu10.hana.ondemand.com -o myOrg -s mySpace -u myEmail@mail.com -p myPassword

Home Assistant

[Home Assistant] Open window reminder

April 18, 2022 May 9, 2022

This automation is triggered when a window stays open for >10 minutes. It will then send a reminder every 10 minutes (max 6 times).

This post helped me to create this script.

alias: Open window reminder
description: ''
trigger:
  - platform: state
    entity_id: binary_sensor.lumi_lumi_sensor_magnet_aq2_xxx_on_off
    from: 'off'
    to: 'on'
    for:
      hours: 0
      minutes: 10
      seconds: 0
condition: []
action:
  - repeat:
      while:
        - condition: state
          entity_id: binary_sensor.lumi_lumi_sensor_magnet_aq2_xxx_on_off
          state: 'on'
        - condition: template
          value_template: '{{ repeat.index <= 6 }}'
      sequence:
        - variables:
            counter: '{{ repeat.index * 10 }}'
        - service: telegram_bot.send_message
          data:
            message: Window is open for {{ counter }} minutes

[ABAP] Include table fields in local type

April 13, 2022 April 13, 2022

Somehow I always forget the syntax for this….

    TYPES: BEGIN OF ty_test.
             INCLUDE TYPE z_table.
    TYPES:   my_new_field TYPE string,
           END OF ty_test.

Home Assistant

[Home Assistant] Control lights with multiple motion sensors

April 3, 2022 April 3, 2022

Create group of motion sensors in groups.yaml
https://www.home-assistant.io/integrations/group/

cellar_motion:
  name: Cellar Presence
  icon: mdi:motion-sensor
  entities:
    - binary_sensor.bewegungsmelder_xxx_ias_zone
    - binary_sensor.bewegungsmelder_xxx_ias_zone

Next, if you have more than one light you’d like to control, create a group of lights in your configuration.yaml
https://www.home-assistant.io/integrations/light.group/

# Light Groups      
light:
  - platform: group
    name: Cellar Lights
    entities:
      - light.ikea_of_sweden_tradfri_bulb_e27_ww_806lm_xxx_level_on_off
      - light.ikea_of_sweden_tradfri_bulb_e27_ww_806lm_xxx_level_on_off

And finally use both in an automation

    entity_id: group.cellar_motion
