When i try compile this sketch it get me error:

mfalkvidd

@pepson you have a stray } after setWaitForConversion

Tip: use ctrl+t in the editor to easier see this type of mistake

pepson

@mfalkvidd
Still is problem after use CTRL+T

@pepson you’re missing a } before start of loop.

@mfalkvidd
Where ? please show me more.... :( i am beginner

pepson

@pepson ok fixed it :)

But.... Can you also help me to add to this sketch option to send to example to Home Assistant also DESCRIPTION to each sensors ? And description will be get from sketch from name about address sensor ?

And in Home assistant show example decription: Ł2 - kinkiet [C10] or for second Salon 2 [A9] etc.
Please help me... because it will be good to identify sensors when add to Controller.
