I just noticed that the app mentioned "there is a software update version 1.44".
But there is version 1.48 on my device currently.
So in other words, I think they made a mistake with firmware checking??

Als ik vervolgens in de app kijk heeft hij de setting ge-reset

Marstek ...

Unfortunately, the battery just jumped back to

- Manual
- 800 Watt
- Open Api off

So the problem has not been resolved for me.

Incidentally, I can now recognize in the Domoticz logs when this happens (see below).
When I subsequently look in the app, it has reset the setting.

Firmware update!
naar 148.119.113

Hopelijk wordt het beter, Ik heb open api weer ingeschakeld en report back hier hoe het gaat

"good" to know I'm not alone.
So this also confirms that if i disable the Open API interface it will not reset the "0 op de meter" setting.
Which is really important for me (obviously).

I also found information on using Modbus over TCP (here https://github.com/evcc-io/evcc/issues/25373 ).
Perhaps I ...

Thanks allot for this plugin.
Currently i'm also using it on my Domoticz.
I have two Marstek E V3 and most of the time things are working fine.
There both connected of a fixed lan cable, no wifi.

The only problem I have and I'm not sure if tis related to this plugin or Open API of the Marstek.
But ...
