Home Assistant - second MMPT ID not found in HA

Hello everyone,

hope there is someone outside who could help me.

HA with all devices are running, except one MPPT (450/100)

In my Credo GX i can see, that he has the ID: 280 but I can't connect him to my HA.

cerbo-gx-devices.pngAre there any ideas?ha-entity.png

This is the code of implementation in HA:

# MPPT 450/100 Westseite

- name: "PV power MPPT 2"

slave: 280

address: 789

data_type: uint16

scan_interval: 10

unit_of_measurement: "W"

scale: 0.10

- name: "Battery voltage MPPT 2"

slave: 280

address: 3700

data_type: uint16

scan_interval: 10

unit_of_measurement: "V"

scale: 100

- name: "Westseite PV power for tracker 0"

slave: 280

address: 3724

data_type: int16

scan_interval: 10

unit_of_measurement: "W"

scale: 1

Thanks a lot,...

Chris

It should work like that. Your modbus.yaml (or maybe they are directly in configuration.yaml) entries look good to me.
Only stange thing is that I don't see a Unit ID 280 in the TCP register list.

Where do I find the TCP register list?

I do have two MMPT 450/100. The other works.

Hi

Unit ID: 280 is not in the list and is needed by HA...

Will this be added to the Excel sheet at some stage?

Now I added a second solar charger. And this one also couldn't be found in HA.

Is there another matching list?

I can't finde the matching for ID: 280 and ID: 281

It would be nice if I could get some help.
