Can you try to run it with invtype=tl3, this might fit better.

Hi I tried tl3 but still strange frequency and SOC for battery is missing

from grott.

Can you sent m ethe original growatt data from the grott log?

I have smart meter SDM630MCT.
Firmware in Inverter is ZBDB-0006, if that is a matter of problem.
Latest firmware seems to be 0014 but I needed 0006 to be able to use the system as a Helsingborg system to balance the net

from grott.

Ok your data record looks more like T:_X (Min-type record) can you please run invtype=min?

the SOC value is then shown at the bdc1_soc keyword (first BCD Power module).

If the SDM630 is connected to the inverter then a separate datarecord is sent and a separate MQTT message is created. Can you look at the Grott log if you can find one?

from grott.

With "min" it finds the data logger(I think) GPGxxxxxx.
I am pretty new with Growatt so I have not learned how it works, yet.
It doesn't find any data for the battery. Before I had the KLNxxxx but that one is not created. I deleted and added Grott integration in HA.
Tomorrow and can try to look through the MQTT messages.
The battery is presented as CXMxxxxx in the Shine app.

So this is what I get when I use -v and changes "minrecl" from 100 to 1
I saw message coming from those layouts:
T060116MIN,T060118MIN, T060119MIN, T060137MIN(could see my serial number for the battery in here), T060120, T060150XMIN, T060150MIN, T060103XMIN, T060104MIN, T060138XMIN
Anyone of these that can help you?

from grott.

T060137XMIN I can see my serial number for each battery module I have

from grott.

If I comment-out Invtype it choose T060104X

and it shows SOC for battery1 in the debug but I do not get it in HA

from grott.

I have the same inverter. Did you find a way to get the battery data in HA? In my case theres no battery data at all no matter what invertype I am using. For me the best way is using invertype "mod". Which one are you using?
