Description

Cool tool. If I see it correctly, only one connection is displayed per inverter.

I have two HMS-1800-t4 with 8 solar panels in operation. However, only port 4 is displayed. Is it possible to query the values of all 8 PV modules?

What I Did

Paste the command(s) you ran and the output.
If there was a crash, please include the traceback here.

After taking a closer look at the output via NodeRed, I saw that I get all the data.
Only Homessistant only shows port 4 because that is always the last module found.

The issue can be closed.

@FrodoVDR thank you for the feedback. I have no experience with HM series so it would be helpful if you could provide raw data from your installation with the following Python code:

from hoymiles_modbus.client import HoymilesModbusTCP
from pprint import pprint

plant_data = HoymilesModbusTCP('1.2.3.4').plant_data
pprint(plant_data)

You may need to install hoymiles-modbus library and replace IP address in the script.

I'm reopening the issue as it seems to be still valid.

PS. you may obfuscate serial numbers if you want.

You have to describe this in more detail, I don't know python where to add the code. I have this running with Docker.

Regardless, my DTU-Pro-s has partially hung today, only after a restart by removing the power supply all values were delivered again.

No problem. We can try reading the data from MQTT.
Execute the command:

mosquitto_sub -h <ip_of_your_mqtt_broker> -v -t "homeassistant/hoymiles_mqtt/#" -u <mqtt_user> -P <mqtt_password>

Skip the two last parameters if your MQTT broker doesn't require authentication.

Wait until the data is published and send me the output.

If you don't have mosquitto_sub, install https://mosquitto.org/download/

The point is that I don't know which data is specific to a port (panel) and which is common for the whole inverter. Hopefully, your input will tell more about this.

PS. hoymiles-mqtt must be running
