I have a bit of an off question. I am running HA in a VM on my proxmox server with some other services. At the moment this server is consuming quite a lot with 6 hdds. I was thinking of turning it off during the night and back on with a WOL script in the morning/ when I need it.
For this reason I need a failback HA server that I was thinking could be run on a raspberry pi in order to monitor my various esps and run the automations.
I water the garden at around 4 am in the morning and in the winter I turn on the heating in the house.
Is it possible to have such a failover HA server? Something that takes over when the main one is down? I am not talking about power cuts like this poster was concerned about:
If there is a power cut then all the ESPs would be dead anyway.
Many devices allow multiple connections and control by multiple servers
Zwavejs MQTT can be controlled/monitored from multiple HA
IP devices can normally be controlled/monitored from multiple devices/servers
You can setup RasPi with HA that monitor 24/7 and only control when main server offline. Ultimately I’d ask why not make the RasPi your permanent HA server as this sounds like pain to manage and possibly less reliable overall
I am reluctant to use the raspi as the main HA beucase I have had raspis die for no reason in the past. I have them in the attic on a UPS and they would just become unreachable. Maybe it was just bad sd cards…
I am looking at the nabu casa yellow with the raspi cm4 but they are quite dificult to find these days. maybe I should get a regular RPi4 and use it with an ssd instead of an sd card…
Thank you for your advice! For now I may have to just create a schedule for the server to bring it bag to life when needed or something like that.
