The home aquarium has interesting side effects. I have finally found time and Home Assistant installed on a Raspi to automate and control various things here in the house. Quite simply a la If/Then/Else principle, just with all the “intelligent” components in the house on a platform. Actually I wanted to pair my cameras with my light control. By chance I came across the fact that the platform I have chosen for this also has one. In practice, that means that I can query all VOC sensors via HA, monitor and react to status changes. This allows exciting automations (a few ideas about which can be argued over): I have not yet completely implemented anything of it but only the VOC sensors put together on one side of the admin interface, see photo in the appendix. Prio currently has the house control but there is a lot of potential to deal with my gadget game drive for a while 🙂 P.S Home Assistant is free, there are clients also for iOS/Android PP.S.Eit and other models for other car manufacturers.
