US vs. EU: Which option is right for me?

HestiaPi Touch is available in two options: US or EU. These determine the power supply input voltage (US: 24V AC, EU: 100-240V AC). The US option supports the C (common) wire in HVAC systems. Even if you live in the US, you may live in a house that does not support the C-wire, so make sure to check which is the right option for you.

No Need to Trade Privacy for Convenience

Our homes are becoming ever more enhanced with complex technologies. With proper automation and coordination of these technologies, our lives will become easier and more comfortable. Coming home after work to find a warm home with hot water ready to use is convenient. However, the very automation that affords us these conveniences also strips us of our privacy by constantly harvesting data about us and shipping it off to companies for marketing and other purposes.

We wanted a home automation solution that preserves our privacy and security, has all the features we need, and is available at a reasonable price. So, we did what engineers do in these situations: we spent time and brain cells to design and develop (and redesign and iterate) what would fit most of the people in the most economical way. As the number of pilot users increased, more features kept being added (and more bugs were squashed). Finally, we reached a point where HestiaPi covers most people’s needs out of the box and almost everyone else’s needs with just a bit of modification.

Open Source Benefits

HestiaPi is ready for makers, hackers, and developers. Because it’s open source, you can:

  • Control your own data
  • Fix your own hardware with off-the-shelf components
  • Add hardware to fit your needs
  • Run the software you want
    • Patch security fixes first
    • Run a custom distro or software
    • Check open ports, services, and logs
  • Create a custom enclosure to fit your location

Designed for Expandability

HestiaPi’s open nature begs for expansion. So far, we have prototyped wireless sensor modules for sensing CO, CO2, various other gases, dust (PM2.5), smoke, temperature, relative humidity, wind speed and direction, water level, water leak, proximity, PIR motion, and magnetic contacts. We’ve also prototyped controlling and monitoring standard relays, power relays, electric motors, water pumps, sirens, lights, and RGB LED strips.

A series of smaller projects are scheduled to deliver the most popular expansions, so you can start building your desired home automation on top of HestiaPi. For less techy people, Sonoff, M5Stack, and other manufacturers already offer solutions that can easily integrate with HestiaPi’s ecosystem.

Easy-to-use Interface Control

HestiaPi Touchscreen

Use HestiaPi’s attractive touchscreen to control the device.

HestiaPi has an easy-to-use, touchscreen interface.

We Support openHAB

HestiaPi is based on the openHAB platform. Use the platform’s accessible web and mobile interface to control HestiaPi.

Most of the cool things HestiaPi can do are because of openHAB. For every HestiaPi purchased a small amount goes back to openHAB Foundation e.V.
