RFM12pi installation error: "rfm12piphp: unrecognized service"

I am trying to install my new RFM12pi following instructions here: http://wiki.openenergymonitor.org/index.php?title=RFM12Pi_V2


I got to the part "upgrading firmware from the Pi".

I have a standard Raspbian so I've followed the second tutorial until this row:

sudo service rfm12piphp stop

That gives me this error

rfm12piphp: unrecognized service

Investigating further I see that I have to install EmonCMS (from here: https://github.com/emoncms/raspberrypi/blob/master/readme.md)...

Can I use the device only to receive data from a wireless DHT22 or I am forced anyway to install EmonCMS?
