Third party integrations

Hello

I have two DEYE inverters in different homes, connected to HA by Solarman integration.
From 02.10.2025 Inverters start to disconnect and then connect
by itself, it seems problem between HA and Solarman.
Solarman Version 25.08.16

After inverter Reload it shows:
1.Initializing

2.Timeout fetching Inverter Dacha data
or
2.Failed setup, will retry: Error setuping Inverter: ‘NoneType’ object has no attribute ‘parser’

Then it connects

And everything repeats after 4-7min.

Dear,
I thought it was a wireless network issue. I’ve replaced the access point, boosted the signal, and even placed a Shelly in the same space to see if it was a network issue, but no.
The symptom I’m experiencing is that the logger effectively stops connecting to the wireless network, but after a while (sometimes hours), it reconnects.
But this happens all day, and naturally, it prevents any automation from working properly.

I am experiencing the same issue since today. The IP of the inverter does not seem to be reachable, then it comes back for an unknown reason. The Deye cloud however has no issue at all.

I have the same problem! The connection was rock solid for weeks and suddenly there are timeouts and the dongle becomes unreachable. There were no changes on my network infrastructure. The connection restores after about 4 minutes.

I changed the 2.4Ghz channel from 11 to 6 yesterday evening and since then I had no more disconnects! I read somewhere that the logger does not like channel 1 and 11.

This is not a bug :wink: When the logger loses connection with the remote server, it reset itself every few minutes. I checked both the Wi-Fi and Ethernet versions. The solution was simple: completely cut it off from the internet and use dummycloud (deye-microinverter-cloud-free/dummycloud/Readme.md at c36009e5c1711aa0f76bd17d63e33322535a87f9 · Hypfer/deye-microinverter-cloud-free · GitHub).

Problems with disconnections and unstable connections have disappeared permanently.
