Are you guys planning on sharing any technical details? Maybe make Grafana data public?

Yeah, that would be interesting data. And the charging setup?

Parked due to bad weather,no charging allowed, even the Victrons are twiddling their thumbs waiting for it to clear...

Hi Shaneyake, maybe we can share more details; I'm just the middleman here forwarding things - not into any details. I'll check.

Certainly doesnt have the added drama that F1 does. But still interesting.

Hi, sorry for not answering, I'm more than happy to share all the info with you.
Let's start with congratulating our team for finishing on position 6 on the 24-hour race!

Have a look at the speed and power graph below, for all of us it was something new and having all the data, we can learn from it, and be better next time.

And another very interesting report is the inside temperature, to have all the battery power used only for driving, the inside heating system was off almost all the time. So sometimes they were driving at temperatures below 10 deg C.

Then we have the battery SOC, as you can see, it was perfectly calculated, so they can finish with the battery completely empty

The race was stopped 2 times, first time because of an accident and second time because of the fog, but as you can see below, from the odometer graph, the total distance they made in this 24h was 620 km

Do you know how this data was collected? Directly off CAN bus?

Hi, yes, I know, there is an API, you can use to collect real-time data and even send commands to the vehicle, more details here - https://www.teslaapi.io/
Then, using Node Red (with this https://flows.nodered.org/node/node-red-contrib-tesla) that data is selected and pushed into an Influx database. Then with Grafana, that data is displayed as those nice graphs. For learning more about installing and using Node Red, Influx and Grafana, please have a look at this video - https://www.youtube.com/watch?v=IkNuadRbANA&ab_channel=VictronEnergy
