Using ESP32 with the Optical Utility Meter LED Pulse Sensor on an interrupt pin as per resources example and uploading to a mysql database evey minute.
Last year I set up the above in April on the incoming electricity meter and let it run. It works very well and seems to be very close to the real meter reading.
I bought another one to go on a solar generation meter I have just fitted. The meter seems to read the same as the micro inverters website readings. But the sensor does not seem to record all the flashes on the meter. I am generating 500wH approx a day, but the Optical Utility Meter LED Pulse Sensor is only getting 100wH ish a day. sometimes it just stops reading for a while and then starts again.
The solar meter is covered in a box to try and block out and light from the Optical Utility Meter LED Pulse Sensor. I have even moved the solar meter and piggy backed it on the incoming supply electricity meter but it never seems to flash.
Could it be a duff Optical Utility Meter LED Pulse Sensor, unfortunately I have cut the end off the cable to wire it on to the board.
Are they easy to ‘break apart’ as I could get it all resoldered at work if that could be the issue.
Any help would be appreciated.
