BrewManiacEx is a brew controller based on ESP8266. It was started by mimicking famous Arduino-based Open ArdBir, so most of Open ArdBir functions are included.

• Manual and Automation brewing process control
• PID and PWM heat control
• Automatic PUMP control

The most important feature that BrewManiacEx differs from Open ArdBir is

• WiFi Enabled, Web-based interface You can view, change the settings, monitor and control the brew on your phones, tablets, and computers.

Additionally,

• Multiple sensors support Up to 5 sensors are supported. Different sensors can be used in different stages.
• PID autotune Run the PID Autotune to get the best PID parameters for your system instead of guessing.
• Sparge water Heating control Run the sparge water heating when the main heating element is idle during mashing to enable using only one 15A/20A GFCI socket.
• Temperature logging chart Watching the temperature chart during brew and after brew
