RE: m30 rs485 compatible energy meter - kiloptero - 07-10-2024
Hi! im ready to order the m30 and a few other stuffs. Need a RS485 meter to connect to the M30 . The attached image rs485 has a specific Yaml file? I can't find information for the 80AMP model. Only for the 40Amp. Any help to proceed the purchase?

already repied your question in another topic. not need let this meter connect to M30, you should connect to Pi's RS485 port.

thanks for the fast response. Don't use a Raspberry Pi.
Maybe im asking something wrong. How to use those ports in the M30?
Ohh Great. A little question. The https://youtu.be/xEvOK3R12kc Use this yaml
for a8
uart:
id: mod_bus
tx_pin: 33
rx_pin: 32
baud_rate: 9600
stop_bits: 1
parity: EVEN
But for m30
uart:
id: modbus_uart
rx_pin: 32
tx_pin: 33
baud_rate: 115200
stop_bits: 1
data_bits: 8
parity: NONE
Need to change in the yaml for the m30 the Uart to the similar in a8?
wich will be correct ?

M30 RS485 port not connected with ESP32's gpio. it's just a MODBUS SLAVE device. if you MUST want use by ESPHome, connect this RS485 wire with other KinCony ESP32 board's RS485 port.

Ohh!great so I can use with the A24 pro for example? in The oficial yaml file for the a24 and the a32 pro there is no info for the rs485.. Can you share how to use the RS485 with the a24? Thanks a lot!!
Maybe adding this to the config yaml file make the magic?
