Thanks for the update. Their reason about security sound fishy to me. Yes, security may be a problem, but there are so many companies using wi-fi home networks without major security problems. I have two devices that not only use my home network, but those companies have their own server that you can connect to, or have to connect to. Once I connect to the company server, as long as my phone stays connected to a wi-fi source, I can go down to the mall do my shopping, and still control my device. Safety and liability would be a more reasonable concern. They may not want someone to be too far away, while monitoring their smoker.
I do have to say it is a nice looking smoker.
