I use the RFM12B's because they handle packets quite efficiently, with decent baudrates for signaling. As for ATtiny vs ATmega: the price difference is relatively small, I went for ATmega's because of their Arduino compatibility. But these are just basic low-level technical choices. I find that both software and mechanical issues take a lot more time to figure out and make decisions...</p> <p>Thanks -jcw</p> Glad you like this Jee stuff.

I spent last couple of months working on similar idea. My sensor network however uses much simpler RF communication - I use Quasar AM 433MHz modules QAM-TX1 / QAM-RX2. I also use ATTiny13/45 for sensors and ATMega8/168 for receiver. Tinys are really dirt cheap, for what they are capable of doing.</p> <p>Anyway I really like your idea of JeeHub / JeeHub. As I am facing very similar kind of issues. I will take a look more closely on your implementation.</p> <p>Keep up good work!</p> <p>Cheers, Stan</p> Hi Jean-Claude,

I have just discovered your blog yesterday, I must say this is really amazing. I spent last couple of months working on similar idea. My sensor network however uses much simpler RF communication – I use Quasar AM 433MHz modules QAM-TX1 / QAM-RX2. I also use ATTiny13/45 for sensors and ATMega8/168 for receiver. Tinys are really dirt cheap, for what they are capable of doing.

Anyway I really like your idea of JeeHub / JeeHub. As I am facing very similar kind of issues. I will take a look more closely on your implementation.

Keep up good work!

Cheers, Stan
