All of our single-probe models connect over Bluetooth, which is a 1-to-1 connection, so you'll only be able to connect with one master device at a time.
However, if your master device is connected to WiFi, you can use MEATER Link to pair your MEATER device to any phone or tablet on that same WiFi network! There's no limit to the amount of mobile devices you can connect over MEATER Link.
If you're using MEATER Block or MEATER Pro XL, they have built-in WiFi capability, so you can connect them with as many phones as you'd like!
