Reading energy export and frequency

[davoau]

Hi, Do you know if its possible to read the export and frequency values and send via mqtt. I have a DDS238 wifi connected to my grid feed, it shows all power going across the DDS238, however it doesn't indicate what direction, as in negative/reverse energy, but on the LCD display of the DDS238 it does show the reverse energy.

I have read that the registers that hold the export data are 21,22,23,24
In the modbus version of the DDS238 it gets this data out, the tasmota code ( file xnrg_09_dds2382.ino) it has:

Energy.export_active = (float)((buffer[19] << 24) + (buffer[20] << 16) + (buffer[21] << 8) + buffer[22]) / 100.0; // 429496729.0 W
float import_active = (float)((buffer[23] << 24) + (buffer[24] << 16) + (buffer[25] << 8) + buffer[26]) / 100.0; // 429496729.0 W

Is it possible to access these registers on the wifi version ?

I have searched and there seemed to be alot of people interested and looking at it but never found any answers.

In the pic below is what I can graph from the mqtt data. On the LCD it says -23 for reverse/export energy, and I would like to get this into home assistant.

Thanks for any help.

the data you want are not available via the tuya interface, only solution would be to use modbus
