Hello,
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 
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:
binary_sensor:
-
platform: seeed_mr24hpc1
someone_exist:
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 (github.com)
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.

Hi there,
Yea that looks like NON ansi compatible Quote Marks ,should be " " compared to what you have. “ ”
fix that.

Not Sure if you still need help but will be beneficial for others too, some changes I made to the code for it to compile are:
Under binary_sensor:
someone_exist to has_target
Under switch
underly_open_function to underlying_open_function
Under button
reset to restart.
Edit to add that the RX and TX Pin are not the correct ones, it should be:
rx_pin: 20
tx_pin: 21
Once you make these changes, it should compile without any issues. Hope this helps.
