MX3000D implementation

[VFLEURET]

Hi, I have MX3000D and I would like to integrate thi in HA.
I can send you log or my config.
thank you for your help.

Hi @VFLEURET,

I just started to add the support for the MX3000D. At the moment there is only the client mode available, which reads the measurements from the inverter.
You can test it, if you install the Dev version of the proxy (HA App).

If you like, you can help to add the emulation mode, which is needed to send the data to the TSUN cloud. With the emulation mode we can find out all other registers and hopefully commands to set power rate etc.

I think you inverters' serial number start with Y00, right? Then you only have to configure the client mode (IP of the inverter, Serial number).

Hi @s-allius
I installed Dev version. Yes, my serial number start with Y00.

I think it's ok but I don't have MQTT Device Inverter in Mosquitto broker. I have Proxy but not inverter.

In my config_hide, I have this :

and my log is

I can send you in MP my configuration

Thanks you

Update: I test with MQTT Explorer and I have data !!

I create manually QTT sensor and now, I have information in my dashboard.

My config yaml :

inverters:

• serial: Y0019348081XXXXX
  monitor_sn: 34276XXXXX
  node_id: "1"
  suggested_area: Solaire_MO1
  modbus_polling: true
  client_mode.host: 192.168.1.11
  client_mode.port: 8899

Thanks !

Hi @VFLEURET,

that's great. But the proxy should register the inverter in HA too. I have to think about this. Maybe I come back to you for some traces.

And there is another point, which is missing. The inverter also supports an emulation mode, so he can send the inverter values to the Tsun cloud in a safe way. This is still missing for the MX3000D. To figure out how to this, I'm looking for a monitor_sn which I can use for a short time. If you are willing to support me, you can write to my private email DataType76@allius.de.

Hi @VFLEURET,

can you check in the MQTT explorer if the proxy sends something on the topics homeassistant?

This topic is used to create the inverters, inputs etc in HA automatically.

---

Another way is, that you set the debug level to debug and restart the proxy. Then we should get more information if the proxy send the autoconfig topics.

I send you proxy.log @DataType76@allius.de
