Thanks! I think I’ve figured it out - it’s a problem specific to our C++/MicroPython driver so didn’t show up on our tests as production test breakouts using big Raspberry Pis. Turns out newer RV3028 chips have a different hardware identification number (0x44 instead of 0x33) so we’ll need to update the driver to accommodate this.
