Hi,

here the same issue with MW3_SSL_5408_1.0B: error: message: "Frame does not contain a valid Modbus RTU frame."

Can you look into it?

Best regards, Jorge

It looks like the readable registers have changed with the firmware update.

https://github.com/binsoul/node-red-contrib-deye-sun-g3/blob/master/src/deye-sun-g3/Action/UpdateAction.ts#L41C10-L41C37

Change const lastRegister = 0x0080 to const lastRegister = 0x007f and it works again.

As a temporary fix until the library is updated: Typically you can find this in node_modules of your installation at ~/.node-red/node_modules/@binsoul/node-red-contrib-deye-sun-g3/dist/deye-sun-g3/Action/UpdateAction.js in the execute() method. Change 0x0080 to 0x007f and restart node-red.

@fschaefer, thank you very much. I can confirm that it works. Published a new version including the fix.
