Rivian R1S and EcoFlow Delta Pro Ultra: A Winning Combo for Home Backup Power

I've been using my phone's hotspot for months, and my Rivian connects to it automatically to run TuneIn and Spotify through the built-in apps on the main display. To be clear, this wasn’t Bluetooth streaming but actual phone data, and the apps worked perfectly without any issues. In Monday for the first time, I saw a Connect+ message pop up, even though the truck was linked to my phone’s data. I can still stream from my phone using Bluetooth, but the sound quality and user experience weren’t as good. This issue started between over-the-air software updates, though it might be tied to a specific date in the system. I tried a soft reset, but nothing changed. Has anyone heard if Rivian changed their policy on this? I remember Connect+ used to mention it provided "data" for streaming apps, suggesting you could use your own data instead. Now, it seems like you need Connect+ just to access the apps at all. I was surprised they allowed phone hotspots to work before, so this might be a deliberate change. I’m okay with paying for Connect+ if this isn’t just a temporary glitch. Any insights would be appreciated.

So I got to test out the beta for ecoflow delta pro ultra and I know of someone that has been using it since last September. It’s an excellent product that provides backup function comparable to a power wall. You can see that ecoflow delta pro ultra can indeed be charged from the Rivian.

So here’s the caveat. If you are using a smart home panel 2, right now you cannot charge from Rivian and power your home at the same time because the AC is disabled while you are connected to the home panel.

However, if you are using a manual transfer switch, it would be possible to use the rivian AC output to charge the battery while you are plugged in a 14-30 cable.

Here’s the caveat. You must verify yourself that the input isnt from your hoke system (aka floating neutral). This is typical for a generator, and actually is the situation for the rivian.

So again, I am not an electrician nor am I your electrician, but it seems like to me that since rivian is a floating neutral inverter, you may use it to charge the DPU at a steady state while the DPU power your home and supplement high current draw devices with its inverter.

Even if you have the smart home panel, you can use the generator input from home panel (if installed) and just use 14-30 to input your DPU there.
