My gen2 stopped data logging, then I did a factory reset and that fixed the problem. About two packs later it's back to not logging. The fan port is also spotty at best. The fan cuts in and out randomly, sometimes I finish a heat at 160° sometimes 205° just depends if the fan decided to stop working or not. That means there is also a problem with keeping the hotwire connected through that port. Is there something I can try or is this a send back for warranty deal?
