I have a question about the De Typhur Sync with two pobes. Surely this probe also has a WiFi connection? this is not named in the description on the site? Surely, in my opinion, technically there should be no difference between the 1, 2 and 4 pobes variant. Second question is the 2 probe variant lists China as the country while the 4 and 1 variant lists Germany. Can anyone tell me if the description is wrong or if I got it wrong. grt, peter
