I decided to buy this used Mastertronic unit that the guy at the LFS was selling. I got a pretty good deal on it and he said he give me some store credit if it had a significant problem I have to fix, but he thought it worked OK as far as he knew. I haven't been able to get the app to see it, but I did get the network setup OK and I can ping it. It did say something about removing port 433 from your firewall. I'm thinking that's the same thing as port forwarding so I put that in the list. I didn't have any firewall settings on my router so I'm not sure what else to try. Yet it still isn't being detected in the app. I guess you have to wait for them to send you the files to re-build the SD card. Is there anyway to get the files sooner online? Its the weekend and I doubt they will get to it anytime soon.
