lyve1981 / growattusbmodbus Goto Github PK

Hello, everyone.

I installed the project and it was relatively easy to set up. However, I don't know exactly how to proceed because I don't know that much about Modbus.

My problem is I don't have all the data I would like in Node-Red. I miss the current power. Here is an example of what I get:

I use the GROWATT SPH 4000TL3 BRA-UP

Thank You

Hi Lyve, using your project to publish to the the registers could I dynamically enable export control on my inverter? This would be incredibly useful.

Hy
allways get a Code error:

Error when compiling

Could you possibly confirm which String.h file to use

Bonjour,

j'ai des erreurs de compilation voir fichier j'ai ajouté les carte esp 8266 merci d'avance de votre aide.
erreur growatt.txt

Do you know if this will work for my inverter?
I alrady flahed a device and if it will work this would be perfekt for me.

Thank you verry much

Have new SPF 3000TL LVM and get this message with two different ESP8266 boards. Suspect Growatt has changed their firmware.
Anyone had any recent success?
Thx in advance

for english see below:
