    Hello, I have a plug here with the LN882H chip and the BL0937 energy monitor.
    I followed the instructions in the existing post about this device. Unfortunately, the hardware is slightly different than described in that post. The boot pin was in a different location, but I managed to reflash the chip with the latest firmware (1-18-247). However, I'm now having trouble getting the BL0937 to work. The LEDs, button, and the relay are functioning. Does anyone have any ideas on how I need to configure the energy monitor to which pins get reasonable readings? Pins 7, 12, and 19 aren't working. I'd be grateful for any tips.
