the problem is not that the command is not working, it is working fine but generates an error in the log

got it working with os.execute, also with -urlencode
Code: Select all
os.execute ('curl --data -urlencode "http://192.168.1.165/light/douchelamp/turn_on?brightness=255&b=255&g=255&effect=Fast%20Pulse"&')

It seems that os.execute don't return errors. Just try with :

Code: Select all

os.execute("thisisan illegalcommand")

So every command you'll give to it will "succeed", even if you ask to execute garbage...

You have to code the error handling.....like

Code: Select all

local status = os.execute("mkdir testfolder")
print(status)  -- 0 at success, otherwise errorcode

thanks. got it working.
i do not need the returncode.
if i execute the command and it works(the light goes on or off) i am fine.

still figuring out if i can avoid this from the esphome side.
