SR04 detection is not consistent

[ErikApption]

PROBLEM DESCRIPTION

On ESP32 and ESP8266, the SR04 is not consistently detected. Sometimes I see the distance but most times it disappears from the main page.

I read other issues related to the SR04 mode - it looks like there is an auto mode detection but I'm worried that it is not consistent. Any chances to get an option command to manually force the SR04 mode?
