Fellow Stagg EKG Pro - Bluetooth App and Variable Temperature Control

Fellow Stagg EKG Pro -- Overview

The Fellow Stagg EKG Pro is a gooseneck electric kettle with variable temperature control, Bluetooth connectivity, and a 60-minute hold function. It's the version of the popular Stagg EKG that adds the Fellow app and a larger 0.9L capacity over the base model. At around $199, it costs roughly twice what a capable non-app kettle costs, and the question is whether Bluetooth and precision temperature control are worth that premium.

The short answer: for pour-over coffee and temperature-sensitive tea, yes. For everything else, probably not.

Who This Kettle Is For

The Stagg EKG Pro is built for people who care about extraction variables. Pour-over coffee, AeroPress, and Chemex brewing all benefit from water at 195-205 F -- not boiling. Green teas extract best at 160-175 F. Boiling everything flat is the most common mistake in home brewing, and a kettle that holds precise temperature removes that variable.

The gooseneck spout is the other core feature. Standard kettle spouts pour fast and unpredictably -- you're fighting the flow rate. The Stagg EKG Pro's narrow curved spout gives you complete control over pour rate, which matters for techniques like the 45-second bloom in pour-over. If you don't do pour-over, the gooseneck is nice but not essential.

Bluetooth and App Control

The Fellow app connects via Bluetooth Low Energy and gives you a few things a button-press kettle doesn't: saved temperature presets for different brews, a built-in stopwatch for timing your pour, and a power toggle from your phone. The app works on iOS and Android.

The Bluetooth range is limited to roughly 10 feet -- this isn't a kettle you're going to start from another room. The practical use of the app is preset management and the timer, not remote operation. You can start the timer on your phone while your hands are busy with a dripper, which is genuinely useful during an active pour.

There is no Wi-Fi and no integration with Google Home, Alexa, or Apple HomeKit. The Stagg EKG Pro is a Bluetooth-only device paired to its own app. It won't appear in your smart home dashboard.

Build Quality and Design

Fellow makes good hardware. The kettle has a matte finish, a counterbalanced handle designed to reduce wrist strain during a slow pour, and a base with an analog-style dial that controls temperature in 1-degree increments. The LCD displays current and target temperature simultaneously.

The 0.9L capacity is larger than the base Stagg EKG (0.6L) and covers most single or double pour-over sessions without refilling. The 60-minute hold keeps water at target temperature without repeated boiling, which helps if your workflow involves prep time between heating and brewing.

Temperature Precision

The EKG Pro holds temperature within 0.1 degrees of target for the full 60-minute hold window. In practice this means the water you pour at minute 3 and minute 45 is effectively the same temperature. This matters less for a single pour-over (which takes 3-4 minutes) and more for longer brewing sessions or situations where you're heating water for multiple people sequentially.

Key Specifications at a Glance

This review covers the Stagg EKG Pro in depth. Key specs at a glance:

• Capacity: 0.9L
• Temperature range: 135-212 F (57-100 C), 1-degree increments
• Hold duration: 60 minutes
• Connectivity: Bluetooth Low Energy, Fellow app (iOS/Android)
• Heating element: 1200W (US models)
• Price: around $199 USD

What It Doesn't Do

No native smart home integration. No Wi-Fi. No Alexa skill or Google Assistant action. If you want a kettle that appears in Home Assistant or triggers automations, the Stagg EKG Pro won't do that out of the box -- there are BLE-based community integrations, but they're unofficial and require setup effort.

The 0.9L maximum capacity limits it for larger households heating multiple cups simultaneously. For 4+ people, a larger conventional kettle is more practical.

Fellow Stagg EKG Pro vs Base Stagg EKG

The base Stagg EKG ($159) has a 0.6L capacity, no Bluetooth, and a slightly smaller footprint. It has the same gooseneck spout, the same temperature range, and the same precision hold -- just without the app or timer. For most users, the base model is the better value. The EKG Pro makes sense if you actively use the app timer during pours or want the larger capacity.

Noise and Build Materials

The Stagg EKG Pro is a quiet kettle. The 1200W element doesn't produce the rattling noise common in cheaper units. The base plate is weighted, which prevents the kettle from sliding during vigorous pours. Fellow uses a stainless steel body with a matte exterior finish -- it doesn't fingerprint the way glossy stainless does.

One practical note: the kettle lid doesn't lock, which is standard for gooseneck designs but worth knowing if you're used to flip-lock lids. During a controlled pour at an angle, the lid stays seated but isn't mechanically retained.

Summary

The Fellow Stagg EKG Pro is the right kettle for pour-over coffee and temperature-sensitive tea. The gooseneck spout, variable temperature, and 60-minute hold are the core value. Bluetooth adds a useful brewing timer and preset management. It's not a smart home device in the hub integration sense -- no Wi-Fi, no Alexa, no Home Assistant. At $199, it's a premium price for what is essentially precision brewing hardware with a well-designed app as a bonus.
