I want to know protocol used in ISolar SMG II 5Kw

[antonio.ste]

i'm trying to read the values from the modbus with node-red, but i can't, if i set port 502 it doesn't connect to the modbus gateway, if i set port 80 it's fine, it connects but of course it doesn't read the values.
Some idea?

[antonio.ste]

I answer myself.
esp-home can only read data from a modbus device and send it to homeassistant.
It is NOT a modbus gateway.
If you want to make the esp32 a modbus gateway, another firmware must be installed.
One solution is to create a flow with nodered, take the data from homeassistant and maybe send it to emoncms for example...

[pongo]

Hello,

from ESPHome you can send data to HomeAssistant, but also to a MQTT server.

Then  Node-Red could read data from MQTT server (for example Mosquitto).

mqtt:
  broker: 192.168.2.32
  client_id: esphome_m5stack_220

In this way all your sensors will be sent also to MQTT.

Using "MQTT Explorer" you can check which messages where sent.

You can also define a custom message

sensor:
  - platform: sdm_meter
    address: 10
      active_power:
        name: "${friendly_name} Power"
        id: ${device_name}_active_power
        unit_of_measurement: "W"
        device_class: power
        on_value:
          then:
            - mqtt.publish:
                topic: domoticz/in
                payload: !lambda |-
                   std::string messageO;
                   char str[16];
                   snprintf(str, sizeof(str), "%.2f", x);
                   messageO += "{\"idx\":438,\"nvalue\":0,\"svalue\":\"";
                   messageO += str;
                   messageO += "\"}";
                   return messageO;

 

Note that if you configure MQTT integration in HomeAssistant, then you will have double messages on HomeAssistant from ESPHome, just use one

[antonio.ste]

Thanks Pongo! I will try it soon as possible

[antonio.ste]

can you explain to me how you loaded the alternative firmware into the datalogger?
Thank you

[Tybord]

You take it apart, and there are the rx, tx 3.3v, gnd, and the gpio0 port and a usb rs232 adapter and ESPHome-Flasher for gpio0 to gnd.

[Tybord]

[Tybord]

srv too gnd

[antonio.ste]

Ok, and if you want to restore original firmware? is possibile?

A simply adapter usb-> rs232 is ok?

[Tybord]

Then you have to save him with the tasomizer in front of him. and you need a usb rs232 adapter that is 3.3v because the esp07 will be destroyed.

[antonio.ste]

Excuse me but I've not understand what is "tasomizer"

[Tybord]

https://github.com/tasmota/tasmotizer

 

[antonio.ste]

Ok, now is all clear.

Wich firmware you have installed? allways esp-home?

Hi Pongo,

I've activate MQTT on Esp-Home dongle and now inverter send all data to mosquito, but there only numbers...

Please can you explain me a little well how to setup it?

 

Thanks

[pongo]

Hello,

what is supposed to view on Node-Red?

You can pass sensor values from Inverter to Node-Red via MQTT, then on Node-Red can select specific topic (sensor) and do what you want with it.

For each inverter sensor/button/... you will have a specific topic on MQTT, for example:

On EpsHome:

On Node-Red:

EspHome:

Node-Red:

If you want to use Node-Red, I suppose you know how to use it. Otherwise, why to use it?

Hi,
what is the set wifi password in your file for network Easun-Smx-Ll-Inverter?

I uploaded your file to the ESP logger but I can't connect to it

[gazzzzton]

you must set your own wifi password at this place

I don't have Home Assistant and I have no way to upload my yaml configuration at the beginning. I want to run ESP Logger and send to MQTT to Domoticz

I think you must find and try other firmware to put in esp because esphome works only with homeassist.

On GitHub I think you can easy find a firmware that read data from modbus and send it to a mqtt server

I found a solution, maybe it will be useful to someone.

You don't need HomeAssistant, you need to install EspHome. And you need original yaml file where you can change everything (including wifi password).

Inside yaml file you can enable/disable HomeAssistant integration and also can send data to domoticz:

If you put

api:

you enable HA integration, if you don't then no integration.

To send data to domoticz:

sensor:
  - platform: modbus_controller
    modbus_controller_id: dds666
    name: "Active Power"
    id: ${id_name}_active_power
    register_type: holding
    address: 0x2004
    unit_of_measurement: "W"
    device_class: power
    value_type: FP32
    accuracy_decimals: 1
    filters:
      - multiply: 1000
    on_value:
      then:
       - mqtt.publish:
           topic: domoticz/in 
           payload: !lambda |-
              std::string messageO;
              char str[256];
              snprintf(str, sizeof(str), "{\"idx\":25666,\"nvalue\":0,\"svalue\":\"%.2f\"}", x);
              messageO += str;
              return messageO;
