Hi, Using a WiFi Adapter, but values are empty. Dump mode shows values . Thanks. 20:38:43.250 MQT: tele/tasmota_A31857/SENSOR = {"Time":"2024-08-31T20:38:43","WE517":{"Energy_Total":0.0,"Power_Total":0.000,"Voltage_L1":0.0,"Voltage_L2":0.0,"Voltage_L3":0.0,"Current_L1":0.00,"Current_L2":0.00,"Current_L3":0.00}} |

Ahhh, uhhhm. Docu says "(SML, OBIS-) signal"... Good point. |

This is beyond my capabilities. I have no idea how to get a single bit out of that meter via infrared. The manual says "It corresponds to the communication standard IR (near infrared) and RS485. IR meets the requirements of the protocol EN62056(IEC1107), and the communication RS485 uses the protocol MODBUS." What is "EN62056", is it OBIS? How do i get this meter to send something or how to get to know it is sending? thanks. |

for MODBUS which i would prefer you need an RS485 to TTL Adapter, then connect the meter via wires and use the above script |

yeah, sigh. Thought it was such a simple thing. The meter has infrared, the small reader has an ESP with WIFI on board.
Maybe I try to drop the led header and use the ESP to read directly from ModBus. Thanks |

Could not connect via IR. Tried IR to USB head, too. Finally ended with a PW11-H ModBus to TCP. Working fine. |

Hello, this is my working script for the ORNO OR-WE-517:
I use a self designed PCB with a ESP07 module. TX is connected to GPIO1, RX to GPIO3 and GPIO4 is used to enable the RS485-Transmitter.
