Hi

Doesn’t look like jsn_sr04m is a valid package and you need to use jsn_sr04t. The following has a bit of info.

Waterproof ultrasonic distance sensors, jsn_sr04t, aj_sr04m or sr04m-2?

[20250126_173240] [20250126_173253] This sensor I bought from a chinese site made me loose about a day of work to get it up and running. At first glance it could be attributed to wrong documentation, this page in particular: https://esphome.io/components/sensor/jsn_sr04t but I actually think that at the time of writing this particular board was not yet around, and then the chinese made a mess with the naming. TLDR: this board (SR04M-2) has to be configured as a JSN-SR04T, from the resistor …

PS I’m not familiar with these but always worth checking the ESPHome official documentation.

JSN-SR04T Waterproof Ultrasonic Range Finder

I use the ultrasonic platform like this:

sensor:
 - platform: ultrasonic
   trigger_pin: GPIO13
   echo_pin: GPIO12
   name: 'Garage Distance Meter'
   update_interval: 5s
   accuracy_decimals: 1
   unit_of_measurement: cm
   pulse_time: 25us
   filters:
    - filter_out: nan
    - delta : 0.02
    - lambda: return (x * 100);

There’s some additional info in this thread as well:

Thanks
I change jsn_sr04m on jsn_sr04t and its ok
