This is without solar cell input, right?

What are the main advantage to this over your board on ebay in terms of battery life?

( I want a long battery life for a ultrasonic snow depth sensor, a DS18B20 and maybe a BMP180 located outside)

I think a typo in the edit of /etc/profile led me to believe that npm was missing, and installed npm with apt-get, and that is NOT the correct way...
Now npm install is in progress, and no errors yet.

connection error - trying to reconnect, I think that is a good error!

node -v gives me
v0.10.28
which node gives me
/opt/node/bin/node, so far soo good.
/opt/mongo/bin/mongo starts.
npm --version
1.1.4

I can not see where in the instructions npm is installed?
(https://github.com/mysensors/Arduino/tree/master/NodeJsController)

And I still don't get why the error message from "npm install" (still) gives me

• npm ERR! node -v v0.6.19

With two almost assembled nodes (ultrasonic distance+ temperature and humidity+temperature+relay) and an almost assembled ethernet gateway I wanted to start with some kind of controller. For me mysensors is still kind of experimental so a separate controller is best.

Setting up a new RPi following the instructions on
https://github.com/mysensors/Arduino/tree/development/NodeJsController
The instructions are straight forward, until the very last step.
npm is missing but that can be solved very quickly with
"sudo apt-get install npm"

With no experience with npm or mongodb I am kind of stuck...

+1 on domoticz integration!

Sure, one or two for testing!

Interesting pcb!
