@yoshi824 Most of us have been where you are now!
I suggest that you try to see the patterns in the code that you have working and try to make the SHT30 work from what you learn.
If it does not work as you want then post here the full code you have and what it is/isn't doing and you should get some help.
@kalina, Thanks. So it will not work for my configuration. Wall switch (push button) is already installed. No possibilities to draw more electrical wires.
Moreover, if i put the board near the light, i have just the Neutral and the return wire from the wall switch. No Live wire to power on the mysensors board.
I think in my ase the best way is to manage everything in my garage in the electrical main board where all the wires are mapped. I can get L + N for mysensors power supply. And i can continue to reuse the original wall switch independently of the Mysensors board.
