Marstek Battery plugin Topic is solved

Power line. Why didn’t I think of that. Ordering a puser at alie now. Thank you for all the responses.

In other news:
I made a plugin for the ct003 to get the data over to Domoticz without the need for a puser.

I dumped the CT003 for a HomeWizzard P1 ...
The CT003 was way to unstable for me

Nice!

About using the dr164 with wifi, there are several solutions :
- a separate plugin
- something like mqmgateway, mobugen
- a script using jq

All recquire a lot more skills and time to get and keep it going

For me i take the dr134, no more thoughts about that. Easy to setup and easy to maintain.

I am using the DR134 to read out data from the Marstek Venus V2 battery as RNEE describes. This works fine with the Light edge mode of this modbus gateway. Also adding aditional register readout like battery voltage and back up relay status is no problem.

My goal is to use the DR134 to change the force charge/discharge/stop register. To start simple I tried to change the back up relay status using the DR134. After a few evenings trying to get this working I think I need some help on this.

Is it possible to send commands to the Marstek battery using the DR134?
Has anybody something like this working?

As test I first would like to send a command to the battery using the DR134 and MQTT Explorer and see that the battery reacts on this.

Domo latest stable version: , on top of a Debian CT running in Proxmox
Version: 2025.1 (build 16782)
Build Hash: 3ed178aa4
Compile Date: 2025-09-12 08:38:25

This plugin was a nice discovery, had some trouble to get python at work on an old beta-version running VM.
Build a seperate new instance, which does work, has python and loads the plugin, , and i see some data from the Marstek CT passing through the logtraces.

As it is a Udp broadcasted datagram which is beeng sent like it seems, is there a possibillity to let it listen to the data fom more than one Marstek-Venus V3 ?

This is the data i see passing when the plugin reads it:

Ive seen this data for couple of days now, the ABC values stay the same, seems there is still something wrong.

Any ideas how to get all three batteries working on this plugin inside Domoticz ?
