Sorry for the late reply. That photacoustic one looks interesting. I have no issue with an extensive initial calibration when it then just works without me needing to take care of it regularly. Thank you :)

Do you have a suggestion for a good air quality sensor (especially for CO2 and VOCs) that outputs reliable results, works over ZigBee and is preferably battery powered? I had a CO2 sensor once but that needed to be calibrated outside really frequently so I stopped using it.
I quickly threw together a repository. But please keep in mind that I made some changes to it, to be able to publish it, and it is a combination of 3 different custom solutions that I made for myself. I have not tested it, so use at your own risk :D But if something is broken, just tell me and I try to fix it.
Sure! I’ll try to do it today but I can’t promise to get to it
I mostly use postgres so I created myself a small docker image, which has the postgres client, restic and cron. It also gets a small bash script which executes pg_dump and then restic to backup the dump. pg_dump can be used while the database is used so no issues there. Restic stores the backup in a volume which points to an NFS share on my NAS. This script is called periodically by cron.
I use this image to start a backup-service alongside every database. So it’s part of the docker-compose.yml
I use FreshRSS with FeedMe and I’m pretty happy with it. Though many local news pages here decided to become assholes and use click bait titles and teaser texts now like “Big car crash! This important main road is closed down”. So no real filtering possible and you again have to open the article to find out where you probably don’t want to drive to.
But still you can define as many filters as you want and save them: FreshRSS
You then also can “share” these filters and subscribe to them separately in your reader app if you want.
Thanks for the recommendation. That is pretty pricey but if it works, that’s fine. Though probably not feasible to have in every room then :D
But I assume it also needs periodic recalibration for the CO2 sensor, right?
