Help requested on modbus configuration

Configuration
1

Hi,

I’ve got ha 2022.6.7 running in a venv. So no container or hassos. I’m trying to talk to modbus but I don’t see a device/switch in Home Assistant. I might be skipping a step or so.
I can talk to modbus with mbpoll from the command line and my heat pump reacts to it (from the command line) as expected so the base setup/wiring is correct and functional.

Below is the relevant part of my configuration. With this in place, restart home-assistant.service, I don’t find anithing modbus*, Airco* airco, … in Home Assistant in devices.

Maybe a bit more info, when click “Check configuration” in the web GUI, I get this:

Invalid config for [modbus]: Structure request 4 bytes, but 1 registers have a size of 2 bytes @ data['modbus'][0]['climates'][0]. Got OrderedDict([('name', 'Airco-Living'), ('slave', 2), ('address', 58), ('input_type', 'holding'), ('count', 1), ('data_type', 'custom'), ('max_temp', 30), ('min_temp', 16), ('offset', 0), ('precision', 2), ('scale', 4), ('structure', '>f'), ('target_temp_register', 4), ('temp_step', 0.5), ('temperature_unit', 'C'), ('scan_interval', 15)]). (See /home/homeassistant/.homeassistant/configuration.yaml, line 12).

Line 12 is: scene: !include scenes.yml
Line 13 is: modbus: !include modbus.yml

And this from the command line works:
mbpoll -q -1 -a 1 -b 9600 -t 4 -r 3 /dev/ttyUSB2 1 # Turn airco off

Now I got rid of the error with the config below, but still I don’t see any Airco-Living device

Is there anyone that can help on this?
