After getting the Home Assistant-based control system up and running, the next steps for my smart RV were the quick wins—in other words, figuring out what works “right out of the box.” Since the Raspberry Pi has a Bluetooth interface, I configured it in Home Assistant. And just like that, I could “see” the batteries (both of which come with built-in BMS) as well as the Victron solar charge controller. The corresponding sensors were then immediately available after I installed the appropriate apps.
An informative dashboard was then quickly built on that foundation.
In subsequent steps, you can set up automations that, for example, notify you when the charge drops below a certain threshold. I implemented the shore power display using my air conditioning control system; more on that later.
