    If I were to add the MOVs on version 1.42u hardware am I correct in each MOV should attach to S01 <> Common, S02 <> Common etc.?

    Also, adding the RFM12B to version 1.42u hardware will provide what benefit and does anyone have an example application?

    Great device!

    Hi Jerry, I suggest connecting each MOV between S0x and Gnd. This way, when lightning creates a high voltage across the solenoid wire and the circuit ground, the MOV will conduct to protect the circuitry.
