Till last year summer I used the dtuGateway also with the HMS-800 Version with DTU Wlite S.
Then came the FW-Update and it doesn't work anymore. There where also problems with the HM-800W but this was fixed.
This was part also from other discussion with the FW-Update from the W-Series.

#109

As I was searching for another topic I found the following....

https://github.com/suaveolent/hoymiles-wifi

I don't know if here are some knowledge from that lib is also used in this project.

What I saw in the history /issues that there was a fix according this communication protocol change last year according the encrypted communication, what I think is the reason why it's not works anymore with my DTU WliteS.

So could this part / fix be integrated here ? I know it's officially not supported the Series without the W.

But maybe it's a look worth.

Here the link to the change what was made in the other project/lib.
https://github.com/suaveolent/hoymiles-wifi/releases/tag/v0.5.0

Hi @zigit780 ,

maybe you can test the first try here -> https://github.com/ohAnd/dtuGateway/actions/runs/26938302511
(extract and choose the right bin for your device)

I could test it, over another person on the location.
So the result is that we don't see any data like power etc.
But we see that the firmware version could be read from the DTU and inverter. So connection in general seems is available.
Here the screenshot.

ok... means we are on a good way ... now we need some more detailing:

=> can read the firmware version, but can't get real power data This means:

Basic connection works — APP_INFO_DATA_REQ (read-only) is always unencrypted
Encryption detection is working — Device recognized as encrypted
But real-time data decryption is failing — REALTIMEDATA (0x0014) messages aren't being decrypted

then let's go with the following:

Serial Logs (Most Important)
Connect to device via USB serial at 115200 baud and capture the first 30-40 seconds after boot. Share EVERYTHING, but specifically look for these patterns:

Should see:

DTUinterface: [ENCRYPTION] Successfully decrypted response (tag: 0x0014, seq: X, len: XXX bytes)
DTUencryption: Encryption enabled
DTUencryption: enc_rand updated

If seeing instead:

DTUinterface: [ENCRYPTION ERROR] Decryption failed for tag 0x0014, sequence X
DTUinterface: [ENCRYPTION WARNING] Plain-text fallback for command tag 0x0014

Encryption Status Endpoint

Visit: http://[device-ip]/api/encryption-info.json

Should return JSON like:

{
  "encryption_enabled": 1,
  "encryption_active": 1,
  "wifi_signal_dbm": -45,
  "wifi_signal_percent": 90,
  "dtu_timeout_ms": 30000
}

Red flags:
encryption_active: 0 → Device not detected as encrypted
wifi_signal_dbm > -75 → Weak signal (>5s timeout)

Device Information

DTU model + firmware version (from UI)
WiFi signal strength
Network bandwidth/latency to device

test procedure:

Reboot the gateway completely
Wait 5 seconds, then capture serial output (copy full log)
Check /api/encryption-info.json (copy JSON)
Check device UI for power data (any values showing?)
Share all three + device model

Yes I have seen, thanks for describing the next step.
Unfortunately I have no access to the inverter at the moment as I'm not on that location.
I will send the result when I have it.
Perhaps in 2 weeks ....
