Add KinCony modbus energy meter to home assistant using raspberry pi's RS485 port

[sebagarayco]

let your bulbs ON for one day, then check the value.

Left five bulbs ON for 24 HRS and meter-consumption didn't change.

What to do ?

the data on the meter's LCD display also no change with "consumption"?

Nothing.... Could the meter be failing?

Any idea if this Yaml file will work with the RS 485 meter connected directly to the M30?


uart:
  id: modbus_uart
  rx_pin: 32
  tx_pin: 33
  baud_rate: 115200
  stop_bits: 1
  data_bits: 8
  parity: NONE


Maybe change for 

uart:
  id: modbus_uart
  rx_pin: 32
  tx_pin: 33
  baud_rate: 9600
  stop_bits: 1
  data_bits: 8
  parity: NONE

this is a RS485 meter, not need work with M30 , only need connect to your Pi's RS485 or USB-RS485 port directly.

Kincony, please confirm if this configuration is correct as METER CONSUMPTION is still showing 0.04kWh. METER CURRENT not showing properly neither

change the meter parity: E
i have tested, only parity: E can use by home assistant.

Check screenshot. I also see 0.04 kwh in the config tool. Could the enery meter be damaged?

After setting Parity to EVEN and updating yaml now I'm having this error in Home Assistant: Pymodbus: hub1: Error: device: 1 address: 100 -> Modbus Error: [Input/Output] Modbus Error: [Invalid Message] No response received, expected at least 4 bytes (0 received)

[admin]

sorry for my mistake, change RS485 " Parity: EVEN " to " Parity: NONE ". NOT "EVEN".
how many days you have used , now total "0.04 kwh"?
