Voltmeter has a minimum voltage of 2.5vLED is likely less than this It might be possible to power the meter separately so it can measure lower voltages https://a.co/d/00Jk5hWH Is a similar meter but with 3 wires On the ones I bought, the red wire was connected to 2 pads. It might work to connect it like this 3 wire meter. Or you could buy this meter.
