Please confirm if your probe has been charged and remove it from the ProTemp Plus Series Stand or 4 in 1 Charger when connected. You can watch the probe connection tutorial here: https://www.youtube.com/watch?v=wU_ypAbdCH4&list=PL1BBFQPP6Q9592Hesn3zbgozt-Ac6hvli&index=7

Please note that a probe can only be connected to one device at a time (including ProTemp S1 and ProTemp Plus Series). If you are unable to connect the probe, you can download and open the LightBlue app and check if you can find “Probe” inside. Each charged probe will display a row of probes in LightBlue.
