Got maestro rod pro with neutral dimmer and it was blinking 1 and 7 led on a 4 light circuit. Played around with it a bit and then it started blinking bottom 3 which means it got fried I believe. Checked the power at the switch and it’s showing 122v which should be no problem. Added a cheap zwave dimmer and it’s working just fine.

figured it was bad dimmer until I tried another ra2 dimmer that is working fine in another light circuit and it showed the over voltage too. I immediately removed it from the circuit and it’s working fine in its original spot.

my electrician checked the circuit and says nothing they can tell. Amy ideas?
