How to auto reboot node every 24 hours ?

Hello.
you have to use a watchdog timer for this. You can use the internal wdt of you mini pro etc.. or use an external hardware wdt.

https://tushev.org/articles/arduino/5/arduino-and-watchdog-timermerci scalz ;)
but if my node (temperature or door) goes to sleep : the watchdog will not be reseted and it will restart ?

- interesting question is which Mysensors version are you using? because v2 should be (or at least in short term) is more robust, there are procedure to reconnect etc in the lib (I know that some jeedom user prefers older version ;) )
During Sleep mode:
Watchdog is used by sleep(x ms). But not used with sleep forever (deep sleep). As you're using sleep(x ms), it should handle that during the sleeping period.During the wake up:
if it's not enabled, look at the links above. But as described, you will need to put your wdt_reset in your main loop or other places, so if there would be some eternal loop or whatever, it would reset as expected (because of non call of wdt_reset).
But if your sketch is still working, but lost comm because you would use older version lib, then wdt reset will still be called, and no reset, and you won't get back your comm..Shortly:
- if it's comm related, sure wdt is a good point, but better to update lib
- if it's sketch related, there may be something blocking somewhere which is not great practice (blocking loop in sketch or in a lib used), in this case wdt will be helpful.
- if it's hardware related, wdt will also be helpful; you could use an external watchog board in this case

hehe :)
in fact it's better to run everything with 2.0, beta version (gw and nodes).I understand that from a user point of view (with a network quite stable), there can be some apprehension.. plus for the moment the ctrler plugin does not have all the types yet.
But maybe if you're a warrior you could give a try and see if it improves. Perhaps try simple with a gw+a node and change freq/channel and test on your computer..What i can say, compared to <2), is v2 (beta has more commits) is optimized (memory&process), mechanism for better comm reliability, and more debug msg (but they don't look the same as v1.x).
And the lib is always improving, for the better! no ads hihi :blush:Look at the docs for changes in sketch between 1.5 and 2.x. nothing fancy, and you will see that with v2 your sketch readibility has been improved. yeah!
I hope that will help! -
Ok !
I will update all my sensors + gw to 2.0 and test it with my sensors (as long as the outside temperatures won't go below 15°C all day I don't need to have my boiler functionnal so I can do some tests :)
If it's ok I stay with 2.0, if not I can go back to 1.5.4 ;)
I'm using just temperature nodes, relay actuator nodes and distance nodes : so all the code is available on mysensors website with 2.0 ;)

I have installed lib 2.0 on my linux virtual machine. When I try to compile temperature node with battery monitoring here is what I got :

@carmelo42
your sketch is compiling well for me. Check your arduino and mysensors lib install (save your Mydoc\Arduino folder if you're not sure) -
weird! that's normally easy. I can't tell you about linux though, i'm using windows.
Arduino 1.6.8 min for me. do you also use Mysensors beta? (it's better for the moment)
For dallastemp, i don't remember, what i can tell you is that your sketch compiled on my machine. and i have not the latest dev version for the moment.
Could you try to compile a simple sketch with no external lib for the moment (like the relay sketch with no button for beginning)? so you will be able to know if it's your arduino/mysensors install.
