The SML read sensor sends data to the meter, although it should not.

The problem

Hello, I have flashed my Hichi SML sensor today from Tasmota to Esphome.

Unfortunately now my grid meter is going crazy. For whatever reason the sensor sends signals to the meter. This causes the meter to run through all the menus. With Tasmota it did not do that. I have an EMH (eHZM-W22E8-0LH00-D5-A5Q2) meter and this is the initial Tasmota code for that meter....

As a workaround, I taped off the TX diode, but that should work differently. What could be the reason?
