yes, i’m using these WS0002 devices.
They work very well and are relatively precise.
The only thing to worry about is the RF “traffic” they produce.
But they are cheap and easy to install to pimatic.
you can post images like this :
the first bracket is the alternative text, the next bracket shows the adress where it’s at.
and don’t forget the ! as first character.
i’ll test some things and will do a “howto” page i guess.
