I'm using a Deye SUN-10K-SG04LP3-EU with Datalogger Serial 23804xxxxx Firmware version LSW3_15_FFFF_1.0.84

I'm getting this error; 022-10-18 20:36:42,724 - DeyeDaemon - INFO - Reading start 2022-10-18 20:36:42,748 - DeyeConnector - DEBUG - Request frame: a5170010450000482ee38d0200000000000000000000000000000103003c001485c9f615 2022-10-18 20:36:49,750 - DeyeConnector - DEBUG - Response frame: a53b0010150007482ee38d020121d0060091010000403e486301032800ffffff160a12162420ffffffffffffffffffffffffffffffffffff0001ffff0001ffff000003e81fa45115 2022-10-18 20:36:49,751 - DeyeModbus - ERROR - Modbus frame is not valid or empty 2022-10-18 20:36:49,758 - DeyeConnector - DEBUG - Request frame: a5170010450000482ee38d02000000000000000000000000000001030050001044171315 2022-10-18 20:36:49,872 - DeyeConnector - DEBUG - Response frame: a5330010150008482ee38d020122d0060091010000403e486301032000010000ffffffffffff0001ffffffffffffffffffff0000ffff0011ffffffff3a005715 2022-10-18 20:36:49,874 - DeyeModbus - ERROR - Modbus frame is not valid or empty 2022-10-18 20:36:49,878 - DeyeConnector - DEBUG - Request frame: a5170010450000482ee38d0200000000000000000000000000000103006d0004d5d47215 2022-10-18 20:36:49,953 - DeyeConnector - DEBUG - Response frame: a51b0010150009482ee38d020122d0060091010000403e486301030800c8ffff00000000dc009315 2022-10-18 20:36:49,954 - DeyeModbus - ERROR - Modbus frame is not valid or empty 2022-10-18 20:36:49,957 - DeyeDaemon - INFO - Reading completed

Hey! @fatexs

Well, my modbus frame validation was too simplistic, and a bit incorrect. I've improved it and implemented a proper CRC check. If you are willing to test it us this docker image https://github.com/kbialek/deye-inverter-mqtt/pkgs/container/deye-inverter-mqtt/46475923?tag=2022.10.1-fix-modbus-crc

Wow! You are a legend! it works now!

Some Values seem odd to me... but could be that the inverter is in standby because its dark outside ;)
