Here's one of the current OVMS developments... integration with the OpenChargeMap Charging Station database which will give us a list of Charging Stations within the range of the car;

Kevin, Thanks.
The RAV4-EV has (at least) two CAN buses, one on the OBD
connector, and one behind a rear left-side panel in the
cargo area. We have logged both of these.

How about the S model?
Does it also have only one CAN bus?
We have logged the CAN bus on the OBD port.

Thanks again, Gary

That's great... don't know if anyone is interested in joining the OVMS developers list and making them aware? Adding new vehicles seems pretty quick and lots of test resource available :-)

Most of the early OVMS supporters were Tesla Roadster owners who also have a Model S now. One of the motivations behind OVMS is to have a single tool that you can use with any EV in your garage.

Is there any such thing as an OBDII splitter so that you can monitor the bus with more then one device at the same time? If so - any links to info?

An OBD "Y" cable:

But, similar cables can be found elsewhere for less,
like at Amazon, as I recall... yes:

Cool - thanks Gary. I'd have thought a splitter would have to be an active device, but this looks like it would do exactly what I want - and for the right price!

The CAN bus is supposed to be a bus, not a star, so try and keep the length of the cables (especially with the "Y") you're using short to keep from bringing the bus down with reflections.
