ProTemp S1 Smart Grill Gauge Thermometer Hub - Wi-Fi & Bluetooth

In this review of the ProTemp S1 the bottom line is simple: this is a practical upgrade for grillers and smokers who want accurate, remote temperature control without a tangle of wires. The ProTemp S1 turns a traditional grill into a networked device with built-in Wi-Fi and Bluetooth, a high-accuracy Platinum sensor that reads up to 1000F, and support for up to four wireless probes. It is best for people who value precise ambient pit monitoring and multi-device management; casual users who do not need remote connectivity or prefer a basic dial may find it more than they need.

Key Features

• Wi-Fi and Bluetooth: Allows remote monitoring and alerts on a phone or Watch so the pit temperature can be watched from anywhere in range of the network.
• Platinum sensor accuracy: Provides roughly ten times the accuracy of traditional dial gauges, which helps maintain steady cooking temperatures for long smokes.
• High temperature range: Measures up to 1000F (530C), making it suitable for searing as well as low-and-slow smoking without risk of exceeding the sensor limits.
• Multi-device support: Monitor up to three S1 hubs in the same app and switch between them with a swipe for easy management of multiple grills or an offset smoker.
• Wireless probe support: Works with up to four wireless probes (sold separately) so users can track both pit ambient and internal meat temperatures concurrently.
• Long battery life: Built-in rechargeable batteries last up to 40 hours on Wi-Fi or about 300 hours using Bluetooth only, reducing the need for frequent recharging.

Who It's For

The ProTemp S1 is aimed at backyard enthusiasts and serious hobbyists who run gas, charcoal, kamado, kamado-style or offset smokers and want accurate ambient pit readings plus remote alerts. It is particularly useful for people who manage multiple cooking devices or need long unattended cooking sessions where precision matters.

It is less appropriate for someone who only grills occasionally and never needs remote monitoring, or for owners of certain very large egg-style cookers explicitly excluded by the size note who should check fit before buying. Those who require a completely waterproof solution for heavy rain should consider additional protection.

Pros & Cons

Pros

• High-precision Platinum sensor delivers much better accuracy than dial gauges for consistent results.
• Wi-Fi and Bluetooth connectivity with app alerts makes remote monitoring straightforward.
• Supports multiple hubs and up to four wireless probes for flexible multi-grill setups.
• Long battery life and a rechargeable design reduce downtime between charges.

Cons

• Bluetooth connectivity receives mixed feedback from customers, so range and pairing may vary by setup.
• Not designed to be exposed in heavy rain despite IP54 resistance; it needs shelter in bad weather.
