Modbus integration PV inverter

Configuration
1

Hi,

I’m trying to add the current power from my older solar array (ABB UNO inverter).
I’ve found out that it is sending the value in 10W (60W in image)

Now I’m trying to read this into home assistant but I cannot figure out why it is not working.
I’m not a programmer.

My yaml code:

modbus:
  - name: PV Inverter
    type: tcp
    host: 192.168.64.87
    port: 502
    sensors:
      - name: PV Inverter Vermogen
        unit_of_measurement: W
        slave: 1
        address: 4088
        input_type: input
        scale: 10.00
        offset: 0

Also, I’m going to use HA mostly for power management / insight together with influx and grafana.
I’m lacking information of my heatpump (LG-therma V) and HP boiler (Nibe).
They have RS485 communication options.

My RPi is too far away from these appliances to run a twisted pair directly.
I’ve found this device at various Chinese sites:
EBTYE OEM/ODM NB114 which should make it possible to go from serial directly to MQQT.

Do you guys think this is a good solution or should I go for a RTU to TCP modbus converter?
I dont like rebooting my system every time adding sensors into the yaml.

Thanks in advance.

address: 4088

Try with 88 or 40088

input_type: input

holding

3

Thanks, already saw the mistake in the extra zero but changing the type to holding did the trick.
