Good job! I have some comments:1) Is it really nesesery to drive the pump through relay? What about transistor with diode? 2) Making the measurement every 10sec is surely an overkill. Also, try to keep it silent during night (I suggest using photo resistor)3) Maybe you'll use it for different plants.. so try to make moisture threshold adjustable Cheers!

Sorry for digging this out :) You mentioned about unwanted interference with both micro-controllers, I have the same, they are too close. The "stuck" is in the network.update() line. I'm not sure if I have good rx code also, because I have other kind of display etc.. so I have some work to do with it ;)

Is there really a need to put "network.update();" line in the transmitter code? It seems that I get very long delay here and sometimes even stuck..
