Speidel Mobile Control — WiFi Fermentation Activity Monitor & Airlock Bubble Counter

The Speidel Mobile Control is a professional-grade WiFi fermentation monitoring device that brings real-time, remote visibility to your fermentation process — measuring airlock bubble activity and temperature simultaneously and transmitting that data via WiFi directly to your personal MySpeidel portal and mobile device. Developed by Speidel as a companion to the Gärmeister CONTROL, the Mobile Control gives brewers who take fermentation seriously the data, the graphs, and the remote monitoring capability to understand, analyse, and optimise every fermentation run from anywhere — without having to be physically present in the brewery.

What makes the Speidel Mobile Control a genuinely powerful fermentation tool is the insight it provides beyond simple temperature monitoring. By counting the bubbles passing through your Speidel airlock and logging that activity against temperature over time, the Mobile Control builds a continuous fermentation activity curve that reveals exactly how your yeast is performing at every stage of fermentation — from the initial lag phase through the exponential growth peak and into the attenuation tail. These clearly visualised graphs on the MySpeidel portal allow you to identify the precise point at which fermentation activity has ceased, giving you a data-driven prediction of your bottling or kegging window rather than an educated guess based on a hydrometer reading taken on a single day. Correlating fermentation activity with temperature data also reveals the direct relationship between your fermentation environment and yeast performance — giving you the information needed to refine your temperature management and optimise flavour development batch after batch.

The Mobile Control connects to your home network via IEEE 802.11 b/g/n WiFi, with onboard LEDs indicating device status at a glance. The included temperature sensor cable connects via mini USB and mounts directly to your fermentation vessel via the included tank screw fitting — a clean, permanent installation that requires no modification to your Speidel fermenter.

Please note: the Speidel Mobile Control is designed exclusively for use with the Speidel airlock — it is not compatible with third-party airlock designs. Airlock not included.
