Second inverter has missing entities

[christof62]

A DTU-Lite-S is used to connect to 2 identical HMT-2250-6T inverters. The second identified inverter has an incomplete list of entities as there are no entities for port 3 - 6. The total number of created entities is 75. This behaviour is reproducable with each configuration attempt.

Here the entities of the second inverter:

And here the first inverter:

Thanks, can you maybe paste the response from the get-real-data-new request from the https://github.com/suaveolent/hoymiles-wifi library? Please only keep the first 4 digits of the serial numbers.

Here the response from the get-real-data-new request. It was already dark, hence there are no values. The library returns only 2 ports of the second inverter.

Thanks, this seems like a similar problem as

I have not yet figured out why that is. Do you have access to the s miles installer app and are you able to capture network traffic via wireshark?

Do you have access to the s miles installer app and are you able to capture network traffic via wireshark?

Yes, but unfortunately not now. This will be possible in about 2 weeks. I am not in the same network as the DTU.

[suaveolent]

That’s great. Maybe you can capture the network traffic sent by the phone to see what is different. I assume you get live data of all your inverters in the app.
