    Has anyone had success with reading the Gen 5's inverter coolant temperature via OBD?

    I've tried using both OBD Fusion and Car Scanner with a Bluetooth dongle to no avail. I've attached screenshots of all the temperature readings, but nothing related to the inverter is showing. As you can see, I've correctly selected the Prius Prime profile as well, so I'm not sure what else to try.

    I'm stumped!

    You sure?
    In Car Scanner Demo mode just now I got the below.
    Searching on "EV" seems to highlight them.
    edit: I bought the 'pro' version...7 bucks?
    edit2: Not using it for gauges because it seems to suck down the phone battery (just noticed I had GPS on even though permissions off-will try in car later with inverter coolant temp enabled.)
    edit3: Using iPhone
