I programmed with ESPHome an ESP32 to display some Home Assistant sensor values on a 16x2 LCD module without using I2C adapter.
It works fine after ESPhome install and compile. But when I reboot the ESP32 module the display does not show values.
Although in the lESP32 log I see the the values are read and updated.
If I install the code again (wifi) it start displaying the values again.
