Rain gauge with scetch https://www.mysensors.org/build/rain

Edit: is it even possible to let the sketch work on an uno?

Hi everybody,

Im trying to build my first mysensors gateway. It is going to be a ethernet w 5100 gateway.

I think its running, i can ping it and when i power it up, domoticz sees it.
Now i build a rain gauge from the how to on this website. I uploaded the scetch to an arduino uno and connected the nrf24l. But i do not see it connecting. I'm new in mysensors and arduino, i do not know what the problem could be....

Thank you for your post. I also found this http://www.seeedstudio.com/forum/viewtopic.php?f=10&t=989&sid=bbe4d6f1ab9f050788e5fa5b41b46069

Can you check my picklist:

Uno r3
W5100 Ethernet shield
Breadboard
Resistors
Some cables
Flowmeters

Can I split the 5v from the uno r3 to the flowmeters?

Hi,
I'm new in mysensors/arduino. I would like to monitor the water usage with 5 flowsensors like the fs400a. It would all be connected to my domoticz setup,if possible by Ethernet.

Because I'm new in this, I do not know how where to start. What do I need? An uno r3 and Ethernet shield?
