Esp32C3 with mmwave sensor, installation in ESPHOME

I am trying to follow this tutorial:

I’ve installed the program in ESPHOME
but I am getting an error message:
[someone_exist] is an invalid option for [binary_sensor.seeed_mr24hpc1]. Please check the indentation.

will appreciate some help :slight_smile:

Looks like, there is an indentation error somewhere in the Python scripts you used. Please check.

Thank you for your reply,
but indentation doesn’t seem to be the problem,
my indentation is exactly as shown on the page:

  • platform: seeed_mr24hpc1


    name: “Presence Information”

the error said indention… so it seems… but i know nothing about it

Try “has_target” instead of “someone_exist”. See this example config from the extension’s github for more detail:
mmwave-kit-external-components/example/mr24hpc1.yaml at main · limengdu/mmwave-kit-external-components (

I should note I am still trying to get this mmwave sensor to work as well per the same tutorial you linked to, I just got past this hurdle already. :smiley:
