azzurro HYBRID inverter can`t recieve value #49

Closed r-schoepf closed 9 months ago

r-schoepf commented 1 year ago

we tried to run the script. Once with a Dietpi and once directly on the Synology, both without success.

We use an Azzurro hybrid inverter with the LSW-3 module.

Is there a possibility that we may ask for your help?

You can run your script in any device of your local network. It's another yet inverter with different address ranges and functional codes. If you have a coding skills in Python you have to find the correct description of modbus protocol suitable for your inverter (maybe this one: https://forum.iobroker.net/assets/uploads/files/1638097185191-modbus-communication-protocol-storage-and-hybrid-inverter.pdf) and try to play with various ranges watching what is coming from. I have found that the fork of this project https://github.com/pawsuch/Sofar_G3_LSW3 is more minimalistic and works better as a starting point.

an for the Sofar_LSW3 we recieve the following error:

File "/root/Temp$/Sofar_LSW3-main/InverterData.py", line 164, in data = clientSocket.recv(1024);

Looks like lack of some python libriaries installed or a different version, that lacks some subroutines.

If you have a plans to run this on Synology I suggest to create Docker container for this script and install everything you need inside it. Synology creates a lot of headache as it's really stripped OS.
