Thanks! I'm looking for a way to upload the FreeCad Files here, but so far the Website does not allow uploading of unknown file types (like *.Fcstd). Cheers!

Please provide the required documentation for the CERN license. See here if anything is unclear.

For those of you who want an extremely simple build, I've reduced it to just 5 parts: one 1-megaohm resistor (0805 SMD) one Arduino Pro Mini one Ra-01 LoRa module Male header pins Battery clips See photos.

@schif Hello, Thanx for you comment. Yes you can use it but use a ceramic capacitor

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!).

I think I found the problem. I think it misbehaved because of an illegal character in the "HOSTNAME". Changed the hostname yesterday and It was still alive this morning even if I have not pinged it.

Just to let you know, that best result I got was when I changed the DHT library (sparkfun) for the one with this sketch. with this sketch. Thank toy for your time. PH

I decided to fix the broken trace I so naively destroyed while breaking the power LED out with a screwdriver. The image from @tripy really helped to figure out which trace I actually broke. It helped a lot to desolder the voltage regulator as well, leaving me with pads I can solder to. I left the regulator out after the repair since I am running the thing from 5V USB. With the regulator out of the way the correct pad was easily identified. Maybe someone else finds this useful, definitly saved my kitchen lighting project today

@akbooer Yes this is what I was seeing on UI7 but nothing on sensor pin for sensor door 1. I was powering it from my USB but I changed it to board(MYS11) power 5v and now it sends the data. This is good now but now I see delays and some times 2 sensors report both on but only 1 is grounded. I'm not sure if that has to do with debounce timers perhaps?

Yes i made several reset, exclusions, inclusions, vera reset and clear EPROM but nothing worked... I made a new sensor and it works perfectly Strange... I will try again when i will have more time. Thanks for the help

I apologize if you are aware of this, but are you pressing the reset button once the sketch is ready to transmit? Using a sparkfun FTDI board with knockoff pro minis, I press the reset button as soon as the first TX light blinks on serial board. If I don't: similar errors.

@hek : Thanks so much... no idea why I didn't see that earlier. I think you can close this post.

@AWI I 'm doing a similar project prodias help me make connections as your project and how to perform with I2C

I'm aware of the superiority of 1.4. Because I just started with building my custom controller I will go with the development branch for now. I really like the new protocol so far. I'm using very basic arduino sketches at the moment. The only thing I'm worried about is my custom controller that I'm building in Node-Red. Hopefully the feature changes will not have to much impact on that part.

thanks you very much work great !
