How can an address be 0? Shouldn't all these addresses be like 30001, 30002 etcetera.? Is there a website where I can enter like: 02 04 24 43 65 C3 A2 43 66 2F 1B 43 63 52 78 00 00 00 00 00 00 00 00 3E 67 71 5D 00 00 00 00 00 00 00 00 42 4B FC 43 18 CC And it shows me all the data? I'm...

That sounds GREAT!, that should be VERY easy to fit into my home assistant, I already have that hardware laying around, please keep us updated! And you're welcome with the logs :)

You are welcome, I'm really looking forward to the Shelly 3EM as an Eastron SDM630 part. I'll try to learn Modbus and play around with it. I think one of the differences between the original sdm630 and the Growatt version, is the extra RS485 output the Growatt version has. None of the other...

last one, two other types of log :D

Same procedure, but another output format.

The inverter connects fine with the meter, but I can't find anywhere to see the meter info in the shinephone app, when I power off the meter the inverter goes into fault mode.

Ok, I have made a common ground using two resistors. and I have checked the baud rate. This is the result. 30 sec with only the inverter on 30 sec with the smart meter started without load 30 sec with 50-51W LED lamp 30 sec with no load

Look very good, ill look for one, I could use a good one in the future, thanks :)

I'll try that sw too, it's quick to do. I have one of those but it's not for USB, but maybe I have a USB uart converter, and that should work. :) I'll try all kinds of stuff later :D

Yes that is exactly the version of USB-rs485 I got. Ok, my job for the day: - I'll check the baud rate - I'll check the inverter to see if it receives the info, the Meter shows in the display - I'll try to make a serial bridge with two resistors. - Make new logging. If that's not enough I'll...

We are at the same timezone :) And no biggy, I just hope my help can solve the riddle, so I can use the home assistant and esphome to generate the "smart meter" data for the inverter.

The inverter and the smart meter only have 2 wires and no ground. My RS485 to USB also only has 2 wires, so I dont think that is an issue. I set the pc to 9600 baud, I'll check up later if that is wrong. I try again later, when I get home from work :)

First one is made with: https://www.com-port-monitoring.com/ advanced version. Hmm ok, what software would you prefer I use?

Another logging program: 30 sec with only the inverter on 30 sec with the smart meter started without load 30 sec with 50-51W LED lamp 30 sec with no load

Ok here we go, this is what I did: 30 sec with only the inverter on 30 sec with the smart meter started without load 30 sec with ca 720W load its a heat gun, so it jumps a little. 30 sec with no load 30 sec with ca 1271w load, same gun as above but with higher settings 30 sec with no load. its...
