I bought one of the Gen 5 4 in 1 sensors, and seems like I get on motion detection and in ICHA reports 255. But 4 minutes later when the 4 in 1 resets, I am not getting the reset within to change it back to 0.
Seems to report everything else correctly on this sensor. Not sure if the sensor isn't sending a reset or if ICHA isn't understanding the command.
