@tiana I have not used it, but it is possible to create different revisions. See https://www.openhardware.io/view/4/EasyNewbie-PCB-for-MySensors#tabs-revisions as an example.
@nca78 I don't use ATAES132A. I put it in just in case I wanted to invest some more time using it.
I now just use SimpleEncryption, it's secure enough for my purpose atm.
(since the area I live in uses KAKU a lot, an insecure 433MHz lightswitch, I don't think anyone would be bothered to hack my temperature sensors. I found 163 433Mhz devices when I left domoticz logging for a couple of days.)
Yes. Correct. call BME.begin() every time and the subroutine only at the beginning.
And you are also correct about the library. I use the "blue" lib, from Sparkfun. As i can recall correct (it's been over a year since I built the damn thing) I have tried both, and found the Sparkfun more stable.
And you CAN switch off power for this module, but after conversion it goes to sleep and uses less than 1uA. Hardly worth the effort, because the current can find a way over the data lines, and that's a pain in the behind to solve (I tried!).
