Guys you are right is too early to quit , i have to try the RFM69 433Mhz as well before quitting , i was planning to wire my house with a 5v power supply to power all the sensors but i guess using a lower freq can help me to avoid that , will give it a try , lest just hope the rfm69 arrive, cuz i always have problems with evay ,
thanks guys you open mi mind one more time
