EAS 3: Electronic combustion control goes digital The new EAS 3 can now also be operated with integrated WLAN via an app. The new EAS 3 is available in two versions. Both variants include wireless access via WLAN. In the familiar design with a glass plate and user interface, the control can be operated via app in addition to the already familiar handling. In the reduced form with an invisible, digital control unit and no display, only access via WLAN and app is provided. The app works on the smartphone in the same way as on the tablet, is free and is intended for access within the reception area of the local home network. Of course, when installing the EAS 3 without a display, make sure that the installation location is within the reception area of the corresponding WLAN router. So that both operation and parameterization are guaranteed. Start at the push of a button The initial commissioning, i.e. the configuration of the heating insert and additional functions, is easily controlled via the app with the EAS 3 without a display. There is a button installed on the control board that starts the connection to the existing internet access. Feedback is provided via an LED status display. In detail it works like this: The EAS 3 is set up as an access point at the factory. The app connects to the controller for the first time, identifies the local WLAN and passes on the access data to the EAS 3. With this information, the EAS 3 automatically switches to the local WLAN and the WLAN symbol is shown in the display variant. Configuration and operation are now possible via the app. Protected tradesman access for the stove-maker specialist company The buttons and setting options familiar from the EAS display version are also available on the app. The burn counter, the operating hours, operating instructions or error displays and the current burn as a temperature curve can be seen at a glance, which makes the app particularly clear. As usual, protected access is available for specialist tradesmen. The heating insert is set here and the known parameter levels are made accessible. Optimized heating behavior BRUNNER controls like the EAS 3 not only control the combustion air supply, which is crucial for optimal combustion. They also recognize typical heating errors such as too little, damp or unsuitable firewood and provide the user with appropriate operating instructions. What is new is the information about the perfect refill time. If it is chosen correctly, the wood ignites itself using the existing embers. Parameters are stored for each heating insert that define the start and end of the perfect re-fueling period. A small flag above the burn curve marks the point at which refills can be made. The second flag is displayed when refilling requires re-heating. A notice: Access to the EAS 3 control via app is only possible in the local reception area of the house network. Remote access via the Internet is not intended for the EAS 3!

Tensor Coffee β€” the companion app for your Tensor One + La Marzocco Linea Micra espresso machine. Tensor Coffee is the official app for the Tensor One precision controller, the engineering-first performance upgrade for the La Marzocco Linea Micra. Where the controller gives you one dial and total control at the machine, this app is where everything comes together: set up your device, design extraction profiles β€” up to full multi-stage pressure curves β€” brew and monitor shots live from your phone, review your shot history, and control the machine itself. Connect over WiFi or Bluetooth and turn guesswork into data-driven espresso that's repeatable to the gram. PAIR AND CONNECT Find your Tensor One over Bluetooth and connect in seconds. Put the controller on your home WiFi straight from the app for a faster connection that reaches across the room β€” Bluetooth stays on as an automatic fallback. Your devices are remembered for instant reconnection. BUILD BREW PROFILES Create and edit the recipes that run on your machine. Design brew-by-time profiles to run a precise extraction on a timer, or brew-by-weight profiles that stop on a target mass when paired with a compatible Bluetooth scale. Set your dose, yield, ratio, image, and name for each profile. PRESSURE PROFILING With the Tensor Profiling Kit installed, shape the extraction itself: multi-stage pressure profiles with up to six stages from 2 to 9 bar, plus blooms β€” full pauses with smooth pressure tapers in and out. The app draws your curve as you design it. BREW FROM YOUR PHONE Start any profile from the app and watch the shot live: timer, weight and flow rate from your scale, and measured pressure traced over your target curve in real time. Stop the shot from your phone at any moment β€” and shots started at the machine appear live in the app too. SHOT HISTORY Your shots are recorded on the controller and sync to the app automatically. Review time, weight, and pressure data, and favorite the shots worth repeating. CONTROL YOUR MACHINE Pair the Tensor One with your Linea Micra and bring the machine into the app: set boiler temperature, adjust steam level, switch standby, and run guided backflush cleaning. Connect by scanning the code on your machine or by signing in with your La Marzocco account β€” the controller holds the connection itself, so it keeps working when your phone is away. Optional Home Assistant integration for home-automation setups. CUSTOMIZE YOUR DISPLAY Upload your own images to the controller's integrated display and assign them to profiles. Crop and frame photos right in the app β€” they sync automatically to every phone paired with your device. Curate the controller's color library with your own custom accent colors, kept in sync between app and dial. SETTINGS AND UPDATES Adjust display brightness, choose how many profiles appear on the dial, manage scales and calibration β€” and install firmware updates the controller downloads securely over its own WiFi. Changes made at the dial appear in the app instantly. GUIDED INSTALLATION Step-by-step, illustrated installation instructions walk you through fitting the Tensor One to your Linea Micra, with a clear progress tracker so you always know what's next. DESIGNED IN ZÜRICH Tensor Coffee products, including the Tensor Coffee app and the Tensor One device, are designed and built in Switzerland for people who treat espresso as a craft β€” replacing manual guesswork with precise, repeatable extraction, shot after shot. Requires a Tensor One controller installed on a La Marzocco Linea Micra. Bluetooth is required for setup; WiFi is recommended for the fastest connection. Pressure profiling requires the Tensor Profiling Kit. Brew-by-weight requires a compatible Bluetooth coffee scale. Machine controls require pairing your Tensor One with the machine; a La Marzocco account is optional.
