I do not know if the Torque app allows you to connect to multiple ECUs, so you could be forced into collecting or atleast gatewaying.
My thought was that if each ECU only responds to requests it knows the answer to, and there's no overlap, there shouldn't be a problem with them all using the same address.
It would be fantastic if this is something that can be added. I love the web interface for programming / tuning / debugging, but once the vehicle is up and running, OBD2 would likely be the better option, at least for monitoring. The ESP8266 drives me a little mad.
The TorquePro definitely connects to multiple ECUs. I use it in Hyundai Ioniq. The gateway is just routing the requests and responses to/from the other buses. The gateway does not collect the data autonomously.

SIGNED32() doesn't appear to work so I brute forced proper handling of signed int32 values.

Thanks! I also have Thunderstruck's CAN-OBD2 translator, so I'll see if I can figure out how to program it with OpenInverter CAN messages... Unless someone has that mapped already. I plan to use OBD PIDs from the stm32 code, probably have remove I upgrade to version with OBD2 messaging coded.
