ChefsTemp ProTemp S1 Smart Grill Gauge Hub Universal — Wi‑Fi & Bluetooth, 1000°F Precision

The ChefsTemp ProTemp S1 is a patented smart grill gauge hub that replaces a dial gauge to provide Wi‑Fi and Bluetooth temperature monitoring, support for up to four wireless probes, and precision readings to 1000°F.

If you want to turn a traditional pellet, charcoal, kamado, or offset smoker into a remotely monitored cooking system, the ProTemp S1 adds accurate ambient sensing, multi‑device control, and long battery life without running wires through your lid. It installs in place of most factory dial gauges, pairs with the ChefsTemp app and accessories, and is designed for weekend pitmasters through serious competition cooks who need dependable data at a glance.

How does the ProTemp S1 fit my grill or smoker?

The ProTemp S1 is available in a Universal version that fits most grills and smokers (not Big Green Egg), and a dedicated BGE version for Big Green Egg and Primo XL Oval models. Installation is designed to be a direct swap for existing dial gauges, minimizing modification.

• Universal fits Kamado Joe, Weber Kettle, Weber Smokey Mountain, Bronco, and many offset smokers.
• BGE version made for Big Green Egg and Primo XL Oval grills.
• Simple replacement of your current dial gauge — no complex drilling on most models.
• Base is fully water‑resistant for outdoor use.

What accuracy and temperature range can I expect?

The S1 uses a platinum sensor that delivers substantially better accuracy than traditional dial gauges and measures temperatures up to 1000°F (530°C). That range handles everything from low‑and‑slow smoking to searing and high‑heat grilling, giving reliable ambient readings for consistent results.

• Platinum sensor for improved precision over mechanical gauges.
• Measures up to 1000°F (530°C) — suitable for searing and smoking.
• 10x more accuracy compared with typical dial gauges.
• Designed to monitor pit/ambient temps, while wireless probes track internal meat temps.

How do the wireless features and probes work during a cook?

The S1 connects by Bluetooth for direct local use and by Wi‑Fi to send real‑time readings and alerts to your phone or watch anywhere you have internet access. It supports up to four wireless probes (sold separately) so you can monitor several cuts or both pit and meat temperatures simultaneously.

• Built‑in Wi‑Fi + Bluetooth for local and remote monitoring.
• Supports up to 4 wireless probes for simultaneous internal temp tracking.
• Real‑time alerts to phone and watch through the ChefsTemp app.
• Monitor up to 3 S1 devices from one app for multi‑pit setups.

What about battery life, weather protection, and extras?

The S1 has a large rechargeable battery that lasts up to 40 hours on Wi‑Fi or up to 300 hours if used with Bluetooth only. The unit carries an IP54 rating for splash resistance; use the optional silicone cover in heavy rain. Optional accessories like the Breezo Fan provide automatic airflow control when paired with the S1.

• Rechargeable battery: up to 40 hours on Wi‑Fi, 300 hours on Bluetooth only.
• Charge with a 5V/2A DC adapter; avoid AC adapters and chargers over 20W.
• IP54 splash resistance; dedicated waterproof silicone cover recommended for heavy weather.
• Pairs with ChefsTemp Breezo Fan for automated airflow control (fan sold separately).

Who is this for? The ChefsTemp ProTemp S1 is aimed at backyard barbecue enthusiasts, competitive smokers, and anyone who prefers a clean, wireless setup without sacrificing accuracy. If you want to upgrade a classic grill or smoker to a smart, app‑driven system—monitoring multiple probes and devices remotely while minimizing cable clutter—the S1 delivers precise ambient readings, long battery life, and easy app control.
