The line between bluetooth sous vide appliances and ones that connect to WiFi is blurred. As of 2017, there’s only one “bluetooth only” device on the market, though you do need to have bluetooth in order to use the the WiFi-enabled ones. Usually, it means you’ll pair the device via Bluetooth, then connect the device to your WiFi signal through your smartphone.
Bluetooth is quite limited in range, so without an additional WiFi feature, you’ll be limited to being as far as “the next room” before you’ll lose remote control. That means other than monitoring your sous vide steak while watching TV (which is still pretty cool), you’ll basically have a regular immersion circulator. I’ll dig into that a bit more below when talking about the only bluetooth sous vide device, but I just wanted to clear up what we’ll be talking about in this post. Yes, it’s going to include the WiFi devices as well.
