Please note that the 4‑in‑1 Probe Charger is designed solely for charging multiple wireless probes at the same time—up to four. The wireless probes cannot connect directly to the app; they must be paired with our smart thermometers, such as the ProTemp S1 or the ProTemp Plus Series. You can watch the probe tutorial here: How to Add a Wireless Probe to ProTemp S1 & Charge It with the 4-in-1 Charger.

If your probe cannot be added via the app, please check the following steps:

  • Ensure your thermometer is turned on, and place it close to the probe so it can receive and transmit the signal properly.
  • Before adding a probe, also ensure your thermometer is connected to Wi‑Fi through the app. The Wi‑Fi icon on the display should be solid (not flashing).
  • Confirm that your probe is fully charged. When connecting, remove it from the ProTemp Plus Stand or 4‑in‑1 Charger, as Bluetooth cannot be detected while the probe is charging in the slot.
  • Please note that each probe can only be connected to one thermometer at a time (either ProTemp S1 or ProTemp 2 Plus).

If you are unsure about the probe’s pairing status, please delete all connections in the app, exit and restart your app, reconnect your thermometer, and then re‑add the probe.
