open-source Rivian drive/charge ledger and trip planner

[pogiant]

After too many road trips spent bouncing between the Rivian app, a charging map, ElectraFi, and ABRP, I built https://rivolt.dev - a single, clean dark-UI Rivian companion that consolidates the things I actually wanted in one place.

What it is
An open-source app that turns your truck's data into:

• Per-drive analytics. Every drive becomes a page: road-snapped route map, speed / SoC / elevation / temperature / headwind charts, energy used, cost priced against your $/kWh rate. No more "wait, what did that drive cost me?" guessing.
• Per-charge ledger. Power curve over time, peak / avg kW, BMS thermal split when Rivian's API feed has it, auto Home/Public/DCFC bucketing. Sessions priced against your home rate, Rivian's reported cost or user-provided price.
• Trip planner with real numbers. Pick origin, destination, departure date/time. Rivian's planner picks stops; Rivolt layers a cost estimate on top - "$32 at chargers, ~$11 in stored energy" - plus categorized commentary on weather, drive mode, and vehicle config (tire pressures, additional weight, etc.). Numbers are computed in code; commentary is just framing.
• Live panel. Real-time SoC, range, GPS, charge state via Rivian's WebSocket feed (1–5s while driving).
• Push notifications for PWA (share web site to your home screen); multi-vehicle support; full JSON export.

What it isn't

• It's read-only. Rivolt can't unlock doors, start charging, or change anything on the truck. Pure telemetry.
• It's open-source and runs at https://rivolt.dev for the hosted version. There's also Docker compose file and Helm chart if you want to self-host it.
• It's in working order - I drive my truck with it every day - but it's a beta. Things might break, but data will persist.
• Your Rivian credentials are yours - AES-256 encrypted at rest, decrypted only in memory at request time, and never stored in plaintext. Rivolt is read-only against the Rivian API - it can't send commands to your truck. You can disconnect and export or delete all your data from Settings at any time. Code is open if you want to verify any of that: github.com/apohor/rivolt

Beta
I'm looking for owners who'll actually plan trips, log charges, and tell me what's broken. Invite-only for now to keep the load sane while the trip-analysis pipeline burns through API tokens.
If you want in, comment below or DM me with:

• Your Rivian model
• Roughly how often you take 200+ mi drives
• Whether you're willing to file a quick GitHub issue when something breaks

I'll send invite codes out shortly.
Screenshots in the https://github.com/apohor/rivolt#readme . Happy to answer questions about the planner, the data model, or anything else.

It seems like you have a well-designed, useful app. I have done 2k and 5k road trips in my R1S, but unfortunately I have nothing planned in the near future. If something comes up, I'd be very interested. I wish you best of luck in completing it.

How does you app differ from Rivian Roamer?

I was just thinking wouldn't it be nice to be able to self host a collection of data from the Rivian in something like Home Assistant. This looks like its going to be a great project. Wish I drove more over 200miles.

You can connect Home Assistant to Rivian and get all the data. But last I checked it’s not neatly organized over time and presented like this project

Curious what the benefit is over ElectraFi. I use it a lot, but the interface isn't great.

Tried to have a look at your link, but get stuck here.

Can't see anything without an account, can't get an account without an invite. Kind of hard to assess if I can help if I can't get any look at it.

I drive about 20k miles a year. I take a 1,200mi round trip about once a quarter, if not more. Then another long road trip on Memorial Day each year (~1,100mi round trip), and a couple off road trips (500mi round trip) twice a year. Be happy to test and help report bugs and such, as well as review the interface on those trips. I have all the historical ElectraFi data I could gather as well if you need/want comparison info.

Anyway I can see the interface ahead of time?

Just tap on a link “request access” and I’ll approve it shortly.

ElectraFi was my main app, but I want something that has modern interface and combines ledger and planner, so I created rivolt

It’s similar, but roamer focused on gamification and doesn’t have planning capabilities, plus rivolt is open source, so anybody can dig into code and propose improvements

thanks! you can try rivolt even if you're not planning anything for near future, it's collecting everyday drives as well

I'm trying to plan a 2500 mile road trip we're taking in a few weeks and currently swearing (a lot) at ABRP and its terrible UI/UX. I just submitted a request for a beta account.

approved, please let me know in case of any issues

Lots of issues...on every page reload the app can't decide if it's connected to my Rivian account or not. Sometimes it shows that it is, sometimes it isn't, and I can't really do anything.

This is AFTER I completed the account connection process successfully:

Then if I refresh the page a few times, it shows connected:

Then if I just let it sit like that for a few seconds, it flips back to the "not connected" state (without me even refreshing.

Trying to flip through the other pages, it's usually the same...often thinks I'm "not connected", occasionally repeatedly refreshing will allow it to see that I am, in fact, connected.

Seems like there's some kind of session state or async issue.

sorry about that, found session state issue, rolling out fix

I agree I was looking a few weeks ago on home assistant integration and it didn't look great. I was looking for a data recorder to see how things trend on a long term basis. What is your polling rate? Does it sync constantly or is there an option to bulk upload like when the truck connects to Wifi? Is the connect plus subscription required (aka high speed data) to use this?
