@n3ro Ok, thanks! Then I learned something new today.. IRQ is only needed for receiving nodes then, like repeaters and gateways, right?
Strange though that my circuit draws so much more current than yours. I have tested different setups, different arduinos and different radios from different suppliers with same result.
Well, at least my mailbox are mysensored now! :smiley:

I think you need the irq only for the gw. I have a receive node without irq.

Do you have changed fuses on your arduino?

And remember. All this stuff is cheap China electronic.The devices can vary consume a lot of electricity.

Nope, havent done that yet. It´s a "stock" 3v3 pro mini. Still reading up on how to do that and how to change to MYS-bootloader, curious on how OTA-update works.
Big thanks for your respons! :smile:

@n3ro - Thanks, that was really helpfull!:smile:

@n3ro Brilliant! He recommends to take out the voltage regulator. it is easier (and works better) just to snip off one leg as described here http://www.mysensors.org/build/battery. I'll try his other mods.... hopefully now my nodes will last forever!!!!

quality project, been having a tinker with mixed results. used sketch from original post, but would it be possible to get a circuit diagram showing pull up locations??? bit of a beginner, but have had a few success with rolling out some power operated sensors , this is my first battery operated sensor...

[n3ro]

No problem. I make one :) give me a day

Hello,
Does this code still work?
Thank you
