@scalz water temperature ? For baby bath ? I'll check if it work with my next coffee. Let me find my ir sensor.

For science !

ps: yes it's working

@Nicklas-Starkel last weekend one of my sensors broke. Both pins were completely corroded and broke

Did you try to just paint the sensors ?
I've seen that here: https://www.tindie.com/products/miceuz/i2c-soil-moisture-sensor/

It doesn't work for me. I go double check the wiring. EDIT: not it's okay now. Great !

But is it possible to use A0-A1, A2-A3, A4-A5 on a atmega328P or there is the same pullup problem ?

I'm asking myself: does an ATMEGA could have a footprint smaller than the arduino nano board ?
For MySensors sketchs I mean. Because we can easily work with 8Mhz, and so, only need 4 composants:

• ATMEGA328P-PU
• 10kohm resistor
• 0.1µF capacitor
• 0.1µF capactior
  With that, a power supply between 2 and 3.3Vcc (because of the NRF, the ATMEGA can handle 5Vcc).

And we have more interrupt pin to play with. It seem to me that it may be an cool alternative design non ?

What do you think ?

Hello everyone,
I would like to make a repeater with tow radio, because my gateway is 2.4Ghz, but i wan't to put outdoor sensors in 433Mhz.

BUT: as i'm not english native, i may haven't found the keyword to find this kind of project into the forum, is there anything like this ?

Thanks, and have a good day !

I've got one for my 3d printer so:
3d printer safety control ! Because we should be next when printing, but we can't.

@iotcrazy It is Jeedom, you can find some information here: http://www.mysensors.org/controller/jeedom
It use an RPI2 if you ant to make it yourself, and a major version will come during the week !

I can't tell you for the moment, I haven't check the real voltage of the CR2032 at the beginning. I'll try to make two mesure between 30 days.
But my sketch is 1800000ms or 30min sleeping (if no-one press the button). Because it's a redundant information, my Jeedom controler have a meteo plugin who's working good. (i'll use it for the mini-night-temperature to have a message if there is glass on my car's windows).

My node doesn't work anymore. Even with new set of accus. I will check again when I'll solder it.

A week.
New accus i think. I do it again but this time, i'm making voltage report with my voltmeter and a picture.

Thanks for the complet answer !

I'm already at 2.73Volts on my two AAA batteries. Is the last sketch a batteries killer ? With a 10 hours sleeping ??

Isn't blacklisting cool too to use ?
Like, if we know the "name" of the sensor lost, we push it to the black list and voila ? This way, we don't have to put a long list a agreed sensors if we have only two nodes outside the house.
... I think.

Too bad, way out of my ability...

Thanks for the answer.
May we trick and use two arduino talking via serial ?
My controller doesn't support two gateway yet.
