Domoticz

Last week i installed a new Marstek Venus E 5,12 Kwh homebattery.
It seems they are flooding the market with these

Runs like " hell" and i love it, but currently it is not incorporated in Domoticz.

It has a modbus RS 485 connection and so i orderd https://nl.aliexpress.com/item/10050068 ... pt=glo2nld this Puser USR-DR132/134 modbus to ethernet convertor at Aliexpress.

I'am going to try to incorporate it in Domoticz.

There are already python tools available and the Homewizard Battery Plugin.

Any thoughts ?

It indeed supports modbus. So you could create a python Domoticz plugin for this.
Or a python application that runs in the background of your system and uses the Domoticz JSON API to publish it's values to Domoticz

Advertisement is a bit tricky... No it does not support 100A, as it is just plugged into your wall

The real max. output is 10.9A = ~2500 Watt (Default 800Watt)

(Which still is nice!)

Maybe this could help you get started:

It is a Chinese Battery (Aren't they all), but they do ping-back to China.

Thank you !

I run it on a seperate group at 2500 watts.

Although i can programm (a little) , have some knowledge of I2C and SPI and C, python is not in my toolbox (!).

I will come back to this as soon as i receive the adapter.
