Describe the bug

Hello,

i'm using the Zendure-HA integration for an year now. But since February 2026 i'm using it with the zenSDK (Local) and ditched the cloud connection completly.

Since two weeks know (Maybe since the beginning but i'm seeing it every day since two weeks know) i'm getting frequently an error in the Log witch look like this:

2026-03-24 14:26:06.080 ERROR (MainThread) [custom_components.zendure_ha.device] HttpGet error SolarFlow 800 Pro 2 !
2026-03-24 14:26:10.082 ERROR (MainThread) [custom_components.zendure_ha.device] HttpPost error SolarFlow 800 Pro 2 !
2026-03-24 14:26:29.965 ERROR (MainThread) [custom_components.zendure_ha.device] HttpGet error SolarFlow 800 Pro 1 Server disconnected!
2026-03-24 14:26:33.966 ERROR (MainThread) [custom_components.zendure_ha.device] HttpGet error SolarFlow 800 Pro 2 !

I'm also noticed that the Zendure Manager changes the Output Values to 0. It Basically stopps working at all.
After 5-10 sec. it starts working again until the next error appears.

In my setup i'm running two SolarFlow 800 Pro with three batteries.
They have an excellent Wifi connection (-32 dBm both!).

In my Unifi setup the internet access to external is blocked for both. But internal there are no rules and fully free to connect to everything. I didn't notice any Problems with the Wifi so far.

I'm running an MQTT Server on my HA with the Mosquitto broker App.
I have also created two HA users for every SolarFlow and connected them in the Zendure App correctly.
They are also showing up in the MQTT Integration in HA with all Entitys.

My Zendure Manager runs on "Smart Mode" and controls discharging and charging.

I cant find an solution for my problme so far. Hopfully some one can help me a bit.

Here are some debuging Logs:

Not sure, if it has something to do with your http-errors. But for the integration you don't need to use the MQTT-settings in the App. If you enable MQTT in the App, it will create an independent MQTT device in HA, which will not be used by the integration.
I propose to disable MQTT in the App, and delete the 2 MQTT-devices SF 800 in HA. Perhaps this 2 independent communication channels interfere with each other.

I also have the same timeout errors (httpGet and httpPost.. with zendure IP and port 80). In my case MQTT is not installed and internet is deactivated in Fritzbox for zendure (only local network via WLAN). Integration (with zenSDK) seems to be working inspite of the errors.
No errors when internet (for zendure) is activated in Fritzbox.
