My first experience with a Stern pin updating the code via WiFi (I have 4 JJP pins and all update via WiFi). Anyway, I powered up Godzilla, went to the service menu, network, software update, and realized that the pin had already started downloading the new code as soon as I powered up. once it finished, I went to update software and that was it. No glitches or problems at all which was welcomed news as I just had to replace my water heater that busted in the night
