[Home Assistant] Open window reminder

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

[Home Assistant] Control lights with multiple motion sensors

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

[Nextcloud] Docker upgrade 21.0.7 to 21.0.8

And again… a Nextcloud upgrade failed. After a docker-compose pull and docker-compose up -d the maintenance mode won’t turn off. So I tried to turn it off manually, but I still couldn’t finish the update via WebGUI. I also couldn’t find any errors via the log.

docker exec --user www-data nextcloud-app_1 php /var/www/html/occ maintenance:mode --off

So I triggered the upgrade again from the terminal and finally got an exception.

Quick search on google and it seems that the image for 21.0.8 is broken and already withdrawn. Here and here. Great if users can still pull it from the docker repo…

I disabled the user_ldap addon via command line. This site helped me finding the right commands. After another occ upgrade and a few minutes, the instance finally came back online.

docker exec --user www-data nextcloud-app_1 php /var/www/html/occ app:list
docker exec --user www-data nextcloud-app_1 php /var/www/html/occ app:disable user_ldap
docker exec --user www-data nextcloud-app_1 php /var/www/html/occ maintenance:mode --off
docker exec --user www-data nextcloud-app_1 php /var/www/html/occ upgrade

In the end I also stumbled across the official nextcloud blog, where they announce 20.0.9 and that they had problems with 20.0.8…. But if the new docker image is not yet provided, and you can’t downgrade from your broken 20.0.8 back to 20.0.7, this doesn’t help you at all.

[Proxmox] Installing Home Assistant

You can install Home Assistant (HA) as LXC or VM on Proxmox. Or even put HA as docker container on top of a LXC or VM, but passing through hardware (like ConBee II) will become much more complicated. There a many installation guides i.e.
https://community.home-assistant.io/t/installing-home-assistant-using-proxmox/201835
https://www.x33u.org/docs/server/home-assistant_proxmox-vm/
https://www.juanmtech.com/install-proxmox-and-virtualize-home-assistant/
and there are few scripts which automate the installing process. Unfortunately some of them doesn’t work anymore for PVE 7 i.e.
https://github.com/whiskerz007/proxmox_hassio_lxc
https://github.com/whiskerz007/proxmox_hassos_install/

The only script that is working (while writing this) is this one https://github.com/tteck/proxmox_haos_vm which is possibly a fork from the previous script from whiskerz007.

[Nextcloud] Docker update 20.0.10 to 21.0.3

As always the nextcloud update failed for me…

After a quick search I found this post. Seems like using mariadb:latest is not a good idea anymore. After switching to mariadb:10.5 and manually turning the maintenance mode off I could proceed the update process.

$ docker exec --user www-data nextcloud-app_1 php /var/www/html/occ maintenance:mode --off

[Wallabag] Docker upgrade 2.3.8. to 2.4.2

Just did an upgrade for Wallabag from Version 2.3.8 to 2.4.2. So I opened my docker-compose.yml and changed the image version and ran docker-compose up -d

version: '3'
services:
  wallabag:
    image: wallabag/wallabag:2.4.2
    container_name: wallabag-app
    restart: unless-stopped
    environment:
      - MYSQL_ROOT_PASSWORD=${MARIADB_ROOT_PASSWORD}
      - SYMFONY__ENV__DATABASE_DRIVER=pdo_mysql
      - SYMFONY__ENV__DATABASE_HOST=wallabag-db
      - SYMFONY__ENV__DATABASE_PORT=3306
      - SYMFONY__ENV__DATABASE_NAME=wallabag
      - SYMFONY__ENV__DATABASE_USER=${MARIADB_USER}
      - SYMFONY__ENV__DATABASE_PASSWORD=${MARIADB_PASSWORD}
      - SYMFONY__ENV__DATABASE_CHARSET=utf8mb4
      - SYMFONY__ENV__MAILER_HOST=${WALLABAG_MAILER_HOST}
      - SYMFONY__ENV__MAILER_USER=~
      - SYMFONY__ENV__MAILER_PASSWORD=~
      - SYMFONY__ENV__FROM_EMAIL=${WALLABAG_FROM_EMAIL}
      - SYMFONY__ENV__DOMAIN_NAME=${WALLABAG_DOMAIN_NAME}
    depends_on:
      - wallabag-db
    volumes:
      - /opt/containers/wallabag/images:/var/www/wallabag/web/assets/images
    networks:
      - proxy

  wallabag-db:
    image: mariadb
    restart: unless-stopped
    container_name: wallabag-db
    environment:
      - MYSQL_ROOT_PASSWORD=${MARIADB_ROOT_PASSWORD}
    volumes:
      - /opt/containers/wallabag/data:/var/lib/mysql
    networks:
      - proxy

networks:
  proxy:
    external: true

But somehow after the upgrade my container won’t come back online. Although the log was saying “Provisioner finished”, it could not connect to the database. When opening the webpage for wallabag the docker logs said: “…unable to parse the MySQL grant string: GRANT USAGE ON entrypoint.sh TO wallabag@% IDENTIFIED BY PASSWORD…”

After searching on google I finally found this note on the Wallabag Github page….

“If there is a version upgrade that needs a database migration. The most easy way to do is running the migrate command:”

docker exec -t wallabag-app /var/www/wallabag/bin/console doctrine:migrations:migrate --env=prod --no-interaction

After running the db migration everything came back online. So this post is just a reminder for myself that sometimes Wallabag needs a db migration after upgrading. 🙂

[Nextcloud] Docker update 20.0.1 to 20.0.4 warnings

After pulling the latest Nextcloud image I got some warnings about missing indices, missing primary keys and about converting some column types to big int. The warnings could easily be fixed by running the suggested occ comands. Append “-no-interaction” to suppress the confirmation question (see docs).

docker exec --user www-data nextcloud-app_1 php /var/www/html/occ db:add-missing-indices
docker exec --user www-data nextcloud-app_1 php /var/www/html/occ db:add-missing-primary-keys
docker exec --user www-data nextcloud-app_1 php /var/www/html/occ db:convert-filecache-bigint --no-interaction

[WordPress] 4 levels of caching

Good overview on: https://www.smarthomebeginner.com/wordpress-on-docker-traefik/#3_WordPress_Caching

Browser Caching: This is what tells the visitors browser to cache the files locally to speed up future site/page visits. We will set this up using Nginx. On Apache, this is accomplished using .htaccess files.

Server Caching: This caches static versions of pages (Page cache). We are going to accomplish this using Nginx FastCGI cache.

Frontend Caching: This means caching WordPress PHP files so they don’t have to be re-compiled for every visit. We are going to set this up using PHP OpCache.

Database Caching: This optimizes database queries by storing them in the RAM for faster delivery. We are going to use Redis for this.

[Nextcloud] Docker upgrade 19.0 to 20.0 exception

Just did the Nextcloud Docker upgrade from version 19.0 to 20.0. I followed their guide on Github and updated my docker-compose.yml.

 nextcloud-app:
    image: nextcloud:20.0
    restart: unless-stopped
    volumes:
      - /opt/containers/nextcloud/app:/var/www/html
    depends_on:
      - nextcloud-db
      - nextcloud-redis
    environment:
        REDIS_HOST: nextcloud-redis
        REDIS_HOST_PASSWORD: ${REDIS_PASSWORD}
    networks:
      - proxy

Followed by:

$ docker-compose -f /opt/containers/nextcloud/docker-compose.yml pull
$ docker-compose -f /opt/containers/nextcloud/docker-compose.yml up -d

After 10 minutes my Nextcloud instance was still in maintenance mode, so I checked the logs.

$ docker logs nextcloud-app_1

Seems like the news app updating process threw an exception. After searching for a minute I found this thread, where someone got the same error and just manually disabled the maintenance mode. So I did the same:

$ docker exec --user www-data nextcloud-app_1 php /var/www/html/occ maintenance:mode --off
Nextcloud or one of the apps require upgrade - only a limited number of commands are available
You may use your browser or the occ upgrade command to do the upgrade

Went back to the WebGui, logged in, and he asked me to update the news app. Now the update finished without problems.
