Here is the latest version of the Room Board, just in:
It works for all combinations of SHT11/DS18B20, PIR/EPIR, and LDR. Here’s SHT11 + PIR + LDR:
And here’s a setup with DS18B20 + EPIR + LDR:
Both can be used with theof the rooms sketch.
But… if look closely at that second board, you’ll see that I still got it wrong!

I’m going to declare victory anyway, and call these boards final. Even though this issue will have to be documented and spelled out everywhere to prevent people from falling into this trap.

Available in the shop now. Foul-ups happen, so be it. End of story.
