Connect Home Assistant with an external InfluxDB (v2)

I assume that the InfluxDB is already running.

load data, buckets, create bucket.
API Tokens, Generate API Tokens, Custom API token. A ReadOnly token for the new bucket is sufficient here.

We store the InfluxDB-Config in a separate .yaml file. This keeps the configuration.yaml somewhat clearer.

We add the following to configuration.yaml:

configuration.yaml

influxdb: !include influxdb.yaml

Bash

openssl s_client -connect <hostname>:636 -showcerts | openssl x509 -noout -serial

The MP4 video files from HEIC files should be removed from all my photos for archiving:

Bash

find . -type f -name "*.HEIC" | while read -r f;do [ -e "${f%.HEIC}.MP4" ] && rm "${f%.HEIC}.MP4";done

Create a DNS-over-HTTPS (DoH) address on the Adguard DNS website. You should know how to do this.

We operate many MS 365 tenants and need the number of devices for financial purposes. This PowerShell script was written for this purpose.

The current version is available on Github

This allows Proxmox (postfix) to use an external mail server:

Bash

apt install libsasl2-modules
