I’m a newbie of homeassistant.
I’ve installed hassio on a raspberry pi 4 and i want read an Eastron SDM230 current sensor via rs485 modbus.
The modbus device on the raspberry is a “classic” USB CH340 dongle.
I’ve inserted in the configuration.yaml
some example found on internet but no sensor shows up in the dashborad.
I’ve inserted this in the configuration.yaml
:
modbus:
- name: SDM230_HOME
type: serial
method: rtu
port: /dev/ttyUSB0
baudrate: 9600
stopbits: 1
bytesize: 8
parity: N
sensors:
platform: modbus
registers:
- name: Grid_Voltage
unit_of_measurement: Volts
slave: 1
register: 0
register_type: input
count: 2
data_type: float32
Restarted home assistant but nothing shows up. Why ?
(/dev/ttyUSB0 is correct. I’ve checked that shows up in the hardware)
