Hi, I have been looking for a WiFi or Zigbee DC meter up to (at least) 500 V for a long time, if anyone has one, or knows where I can buy one, please let me know
Perhaps the easiest way is to use the LE-01DC DC energy meter (up to 1000V) and use the built-in RS485 communication interface. RS485 and the Modbus RTU protocol?
