Just wondering if you can use more than one ET-73 at the same time? So as to monitor two different meats at once from inside the house. I know I could use a second meat probe for the second meat but then I would loose my smoker temp probe. I have one ET-73 and has worked just as advertised. I am going to pull and overnight-er tonight while doing 2 butts. I'd like to get some sleep so I bought a second ET-73 the other day so as to be able to monitor each butt separately. I have not yet tried it but was hoping someone has already. My only concern is pairing the individual units so they don't get confused. I hope they have multiple channels they can send on. Any experience?
