General

How accurate is Kegbot?

A properly installed and mainted system is very accurate. We routinely see less than a 1-2% margin of error, which is the published accuracy of the underlying flow sensor.

The Kegbot app includes a built-in calibration wizard, so you can adjust the behavior depending on your system.

Can I disable features I'm not interested in?

Absolutely. We've built many Kegbot systems and realize one size does not fit all. Most Kegbot features are optional and can be disabled.

I don't want to share my drinking history. Can I still use Kegbot?

Yes. Kegbot Server has system-wide privacy settings. The manager of a server can place it in "Members Only" mode (only authorized users can view data), or disable all public access entirely.

Why not use another type of sensor, such as a scale?

Simply put, we've had the best results from inline flow sensors. They work well, don't tend to require calibration, and are available relatively cheaply. Scale-based systems we've seen have been more brittle, more expensive, or both.

That said, the sensing component is mostly decoupled from the rest of the Kegbot stack. So if a better sensor becomes available, it should be simple to add support for it, without major changes in the app or server.

Can Kegbot cut drinkers off according to BAC?

No. Absorbed BAC varies from person to person (and many other factors), and can only be approximated — poorly.

Responsible drinking is a job for humans, not bots.

When was Kegbot created?

Kegbot was started in late 2003. By 2004, the system stabilized and mail list opened up, and in 2005, Kegbot was written up in Popular Science, MAKE Magazine, and several other places.

We're pretty certain that Kegbot was the very first open source project to bring keg volume, keg access control, and the internet all together!

Kegbot Ecosystem

Do I have to install Kegbot Server?

Not necessarily, but it is highly recommended. With purchase of a compatible Android tablet and the Kegbot Tap Conversion Kit, you will be able to monitor taps, kegs, volume, and pours. However, you will be missing many attractive features that are offered only by successfully installing and configuring Kegbot Server.

What drinker assignment/authentication methods are supported out-of-the-box?

Kegbot natively supports NFC user authentication on tablets that offer NFC compatibility

The Kegbot app also allows users to choose (tap) their drinker account to assign pours, but these assignments are unauthenticated

What physical access control methods (turning taps on/off) are supported out-of-the-box?

None, currently - but plug-and-play access control is on our roadmap

What do I need to set up multiple taps?

Team Kegbot highly recommends purchasing one Tap Conversion Kit, installing Kegbot Server, and configuring the system to your taste. Only after successfully installing and maintaining the Kegbot ecosystem on one tap should you consider extending the Kegbot system to accommodate multiple taps.

If you're happy with the feature set, the simplest way to set up multiple taps is to purchase multiple Tap Conversion Kits - one kit per tap. Kegbot employs a many-to-many approach, in that Kegbot Server can accommodate multiple tablets, and the Kegbot app on each tablet can accommodate multiple Kegboards (via a powered USB hub).

If you find the feature set lacking for your particular needs, tell us what we're missing! We're consistently rolling out new features to accommodate our many varied customer sets.

Tablet Compatibility

What tablets are compatible with Kegbot?

In general, any Android tablet that supports USB OTG / Host-Mode with a screen 7" or larger

Does Kegbot work with iOS devices (iPhone, iPad)?

Not currently. It is on our roadmap for future development

Kegboard Pro Mini

Does the Kegboard Pro Mini support multiple flow meters?

Yes and no. The simplest (and our officially supported) solution to configure multiple taps is to purchase multiple Tap Conversion Kits - One Kit per Tap. However, the KBPM is capable of supporting up to two flow meters via a Kegboard Coaster build or through other DIY methods

Does the Kegboard Pro Mini support RFID or other OneWire user authentication?

Yes and no. It does not work as a plug-and-play unit out-of-the-box, but you may decide to build an authentication dongle through DIY methods. A plug-and-play authentication solution is on our roadmap for future development.

Does the Kegboard Pro Mini support temperature monitoring?

Yes and no. It does not work as a plug-and-play unit out-of-the-box, but you may decide to add a temperature sensor through DIY methods. A plug-and-play temperature monitoring solution is on our roadmap for future development.

Does the Kegboard Pro Mini support access control (turning taps on and off)?

Not currently. A plug-and-play access control solution is on our roadmap for future development.

Is there a case or enclosure available for the Kegboard Pro Mini?

Not officially. User dcowan has posted his schematics for MakerBot. Other users have used a Hammond Project Box. Most users keep the KBPM bare.

Kegbot Server

Can I install Kegbot Server on an external hosting site?

Yes, but with a number of caveats. Your hosting provider has to allow several key features like sudo access, the ability to install python packages from the command line, and the ability to serve up a wsgi application. Some VPS servers and most dedicated servers allow some form of this, but the full capabilities vary from provider to provider and we're in no position to make recommendations regarding which providers are compatible with Kegbot installation.

I don't have a Linux machine at home, how can I install Kegbot Server?

If your computer(s) at home are Windows or Mac machines, one route you could take is installing Linux on a virtual machine. VirtualBox is a free option. And since you're the owner/installer, you will have all the access you need to get Kegbot Server up and running.

Alternatively, you can dedicate a Raspberry Pi device to Kegbot. It's a little slow / underpowered, but it just works. Simply put together a virgin RPi and follow the Kegberry instructions.

Should I install Kegbot Server via pip or git?

pip is the preferred install method for the typical user. Version upgrades are fairly stable.

git is the preferred install method for developers and users who want bleeding-edge (read: sometimes unstable) updates.

Do-It-Yourself

Can I build my own Kegboard?

Yes. Kegbot's hardware schematics, firmware, and software are all open source. However, you must be handy with a soldering iron and source your own parts. While Team Kegbot no longer officially supports/troubleshoots do-it-yourself (DIY) builds, you may find help from the community in our DIY forum.

Can I use a flow meter other than the SF800-RJ?

Yes. Please see the Kegboard Pro Mini external device compatibility specs. Again, modifying our product offering will require some elbow grease and will not be supported to the same level of our Tap Conversion Kit. All support requests should be directed to DIY Corner.

Developers

I've got an idea! How do I contribute to Kegbot?

The best way to get started is to send us a bug report or pull request on Github. You can also chat with Kegbot devs in #kegbot on freenode.

Licensing, Branding

How can I use Kegbot in my bar?

Right now, our focus is on supporting non-commercial, home/office users.

However, we're constantly working on new opportunities for Kegbot, and we do know of multiple commercially-installed Kegbot systems. For more information, contact our parent company, Bevbot LLC.

Can I use the name "Kegbot" in my own project/product?

We've worked hard for our name! Especially because of misunderstandings in the past, we kindly ask that you do not use the Kegbot name without our prior written permission.

We always make an exception for free, open source projects that are designed to work with the Kegbot system: for example, kegbot-api-java or kegbot-friendster-plugin.

If in doubt, get in touch! We're nice, and will try to respond quickly.
