SML checksum error since August update still ongoing (ESP32 WROOM) #5213

The problem

After the update of ESPhome in summer 2023 I recive checksum error in received SML data. After several seconds or minutes one massage can be read without errors. Before the update, I recived every 1-2 sec. a value. Tips like pr#5271 don't work. Lookup table change to small one is maybe not to good for my board. Any posibility to change to big lookup table? Any hints?

Which version of ESPHome has the issue?

2023.11.6
