Curl from Windows to HASS

Configuration
1

I’m trying to trigger a sensor (or input boolean, does not matter that much) from a Win7 machine to HASS.

Got myself a windows Curl version from here and trying to execute (as a test):
curl -v -H "Content-Type: application/json" -X POST -d '{"entity_id":"light.bank_tolomeo_40","brightness":"255"}' http://192.168.1.196:8123/api/services/light/turn_on?api_password=XXXXX

This works perfectly fine via Putty on my HASS RPI however if I execute same on my windows machine I get:

Note: Unnecessary use of -X or --request, POST is already inferred.
*   Trying 192.168.1.196...

In the HASS logs this generates:

Any ideas?

Here is an example of a working CURL command that I use from windows:

curl -X POST ^
	-H "Content-Type: application/json" ^
	-H "x-ha-access: mysecretpassword" ^
	-d "{\"state\": \"true\"}" ^
	--ssl-no-revoke ^
	https://myhadomain/api/states/binary_sensor.homer_in_use

I do this from a batch file, so the ^ are line continuation characters.

Thanks! Do you mind sharing which Curl for windows you use? There are several versions out there.

In the meantime found an alternative way to solve this. Thanks for your help so far!

Could you please share your solution. I cannot get that batch file to work with the specified version of curl.

Could not get this to work. For the specific use case I found another solution. Its posted here

Thanks @treno! This works perfectly and is exactly what i was looking for. Do you know how to do an if statement in batch based on the entitie’s state? Like if media_player.tv == “on” then run next line etc…
