Hi all,

finally i rewrite a code for myself. There is no More EEPROM usage at all.
I'm using MajorDoMo (http://majordomohome.com/) and it more suitable for me to have a 10 minutes counts from Rain Gauge.

Here is my new code:

#define MY_RFM69_ENABLE_ENCRYPTION

 * The MySensors Arduino library handles the wireless radio link and protocol
 * between your home built sensors/actuators and HA controller of choice.
 * The sensors forms a self healing radio network with optional repeaters. Each
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * network topology allowing messages to be routed to nodes.

And now i able to see when it was a rain and how strong it was ;-)
