KinCony RS485 energy meter RS485 modbus protocol - admin - 12-14-2022
Modbus-RTU: 9600 E 8 1 read function:03
Register address data data type-IEEE-754 function
0000, 0001 power consumption (kWh) Float read
0100, 0101 voltage (V) Float read
0106, 0107 current (A) Float read
0118, 0119 power (kW) Float read
0142, 0143 power factor Float read
0144, 0145 frequency Float read
How to change meter ID, for example: change ID:01 to 20 just send command:
01 10 0D B0 00 01 02 00 14 60 AF
first (01) current ID
14 is (20) decimal
60 AF (CRC)
RE: KinCony RS485 energy meter RS485 modbus protocol - kiloptero - 07-13-2024
can you share the yaml to use with a a24 or a32 for this model and the 80amp too.?
Maybe adding this to the oficial yaml will work?

just relace A24 RXD, TXD pins:
RS485:
RXD:GPIO32
TXD:GPIO33
here is ESP32 pin define for A24: https://www.kincony.com/forum/showthread.php?tid=3921
RE: KinCony RS485 energy meter RS485 modbus protocol - kiloptero - 07-14-2024
Thanks and sorry for all the post.
As I see in the yaml config I already post the RX And Tx are correct. its ok?
uart:
id: mod_bus
tx_pin: 33
rx_pin: 32
baud_rate: 9600
stop_bits: 1
parity: EVEN
Another question.. in the address number of the sensors.. Area ok?
For example. " address: 0x64"
sensor:
- platform: modbus_controller
modbus_controller_id: a24
name: "Voltage"
id: modbus_voltage
register_type: holding
address: 0x64
unit_of_measurement: "V"
value_type: FP32

when you received package, connect to your meter, have a test, then will know whether correct.
RE: KinCony RS485 energy meter RS485 modbus protocol - kiloptero - 07-14-2024
Ok, I will test and post the information. Thanks for all the support!
RE: KinCony RS485 energy meter RS485 modbus protocol - admin - 07-15-2024
you are welcome.
RE: KinCony RS485 energy meter RS485 modbus protocol - admin - 07-20-2024
because the meter is NEW, so the consumption is 0, it's first time to use.
RE: KinCony RS485 energy meter RS485 modbus protocol - kiloptero - 07-20-2024
After some test and the infinite patience of mr kincony I managed to get the rs485 to work totally with the a24 via the rs485 port (model 80a). At power up the device says the address in my case 222 which in the hex code is address: 0xDE (I will attach the yaml anyway).
Things to keep in mind, the physical device shows in KW so for testing it is possible that it will show 0 if it has little W. Do the test with a hairdryer or something that consumes a lot of power. Remember that it is for the board so I doubt that you have less than 150w base consumption in a home.
I would like to ask mr kincony a question. Is it possible to change the power from KW to W? This would allow me to show more clearly the values in H.A. This could be done by connecting it to the rs485 via a usb cable? It would be great if we had the option. @admin
Another issue is that if you want to show it in the energy dashboard you have to put state class and device class (it goes in the yaml).
Well I hope you all can use it and thanks again to the forum for the help.

1. read modbus register data from meter unit is "KW". if you want show "W" in home assistant. you can let value*1000 , then change unit to "W".
2. how to add to home assistant energy dashboard, see here guide: https://www.kincony.com/forum/showthread.php?tid=5853
