Connecting a Vaillant aroSTOR / Viessmann VITOCAL - thermodynamic water heater

Hardware

Hello,

I am considering acquiring a Vaillant aroSTOR, but it doesn’t specify connectivity options. While looking at the schema, p.28, do you think something interesting can be done?

I had found a that someone had connected to it in UART. Could it be to the X1 bus instead of the control panel? Could it be that it’s using an eBus protocol?

Thanks in advance.

It seems that the Vaillant is out of stock. I can hopefully fall back on a Viessmann VITOCAL 060-A. Can the “Premium/economy tariffs” be used with a relay (e.g. a Shelly) to remote control such a device?

I don’t find many other options. Do you?
