Hi everyone,
My name's Carmine and I'm an hobbyst homebrewer from Italy.
Among my interests (brewing aside), there's electronics and software development, and that's
what has pushed me and a couple of home brewer friends to build AxHTherm.
AxHTherm is a fermentation and mashing control system
Fermentation and mash can be controlled by means of a temperature profile.
Up to three temperature sensors (DS18B20) can be attached to the system, of which one
will be the active probe and the remaining 2 will be used for monitoring (i.e. chamber and environment temperature monitors)
A temperature profile consists of up to 5 control steps, and each one can be of either one of
the following kinds:
The system is remotely controllable by means of a web application, and supports OTA updates.
Another interesting (IMHO) feature is the capability to connect to external services such as:
AxHTherm is comprises two parts a PCB which hosts all required hardware and a GUI.
As of today the GUI is build for Android devices (and it is available on Google's play sotore), but
a web version will be available as soon as we have finished polishing the Android version.
Doc..ehm..entation wise, we've just started writing something, and getting a blog ready. So, for now,
the most reliable source for documentation is our telegram channel.
Hoping to have whet your appetite, I look forward to hear from you and exchange thoughts.
Cheers

A temperature profile consists of up to 5 control steps, and each one can be of either one of
the following kinds:
- Fixed temperature point
- Holds temperature at given set point (within probe's tolerance)
- Time and temperature controlled ramp
- Ramps (up or down) the temperature changing the set point at computed intervals given the duration.
- Time and temperature controlled ramp with max velocity settings
- Ramps (up or down) the temperature changing the set point of given amount (degrees/hour)
- Gravity controlled (interfaces with iSpindel and Tilt hydrometers)
- The system holds the temperature like the fixed point but considers a step completed once the gravity reaches the desired value.
- PID controller (for mashing)
- The system holds the desired temperature for the given time using PID control algorithm
The system is remotely controllable by means of a web application, and supports OTA updates.
Another interesting (IMHO) feature is the capability to connect to external services such as:
- ThingSpeak for logging and graphing
- IFTTT to receive step change notifications
