Well I’ll just have to wait what the Seeed guys sat 
.
Can you give a estimation on the range?
How is your experience with “noise” and “interference” from other wireless products operating at 434 MHz (car alarm/doors ect…)? This because I’ll probably will have some of these in the surrounding area (cars in the street).
Why are you using another library? Is the virtualWire library no good enough?
Best regards.
