  @user2684 It appears that this problem is caused by a bug in bootloaders used in some Arduino boards.

  The solution suggested is to flash optiboot bootloader to the Arduino Pro Mini. Or not using a bootloader.

  I use mostly barebone atmega328's with optiboot bootloader, working perfectly with reboot function, so I haven't been aware of the problem until now when I used a pro mini.

  Please read this article which explains the cause of the problem and suggested fix.

  I will try it on a pro mini when I have time.

  I just want to know If I understand correctly 3d model is not a part of the footprint in KiCad and there is no feature to create hard link footprint and 3d model when I prepare footprints. Is it correct?

  Hi @user2684 thanks a lot for your reply! I started to put in different values first for the Beta-c, nothing happened. Then I tried to change the value of the resistance of the probe, noting happened but when changing the reference resistance then I got a change. I started to measure and I found that the 2,5mm female connection (bought from China) for the probe was extremely high resistance so I soldered the probe connections directly to the board and now it works!!! Sorry for taking your time but I must say that nodemanager is amazing! I have no kompetente or skills in electronics or programming and still I got this to work (with a little help from you)! Now I just have to solder everyiting togheter and put in a box and start using it! I will follow the development and for sure do more projects using Node Manager!

  Thanks again for for taking your time!

  Yes, I do have it on a UPS. What I meant is that if I power down the PI. I think the SD cards is toast on it. Nothing seems to be saved to disk - I made a cron job and saved it. But, after a reboot of the Pi the cron job was no longer there. Oh well.

  I have stated to mess with dashticz - looks promising but not ready for prime time. Documentation is thin, to say the least. Also, the config switch to use F instead of C works for the numeric value shown - but the suffix is still "C". Also, the culture set is using (for the US, anyway) the wrong thousands separator and decimal point characters. I can add in my Google Maps API key in the locations in the config (with my lat/lon) but it does not appear to "do" anything and I see nothing in the docs on what block or section I need to create to show the maps.

  Still, I do like Domoticz.

  @tombstone thanks.

  Trying to run some tests today. I think I have some workable code, but I don't have any sleep figured in yet. With all of the sensors being run from one pro mini, there is a lot going on and I will need to figure sleep in carefully if I even do. I have temp, humidity, rain, wind direction and wind speed. Arduino IDE says that it takes 75% of the program memory and that is not with debugging on. If I turn that on I start to get warnings, but it will compile and run.

  Getting even closer to being able to mount this on my roof.
