Have an ac measure module connected to an m5stickCplus. Using the example code. Firmware returns only the number 1, data will only update for about 5 seconds, then the led on the ac measure module goes off and data transfer stops immediately. This occurs whether or not there is voltage on the line and neutral inputs. Another user suggests that current must be detected for the module to function. Is this true?

AC Measure module shutting down
RE: AC Measure Module Problem
@edpaay Did you find a way to use the ac voltage detector? I am having the exact same issue. It powers down when it measures no current even if voltage is present. We intended to use it to detect a stray voltage, but cannot use it if we have to have a load connected...
