HestiaPi Touch is a completely open source smart thermostat for your home. With it, you can monitor your home’s temperature, relative humidity, and atmospheric pressure. You can also control your heating, ventilation, air conditioning, hot water, and more from anywhere you have an Internet connection. You can do all this securely and with confidence your private data stays private. HestiaPi Touch is compatible with many devices and home automation systems and can serve as a central point of control that ties them all together in your home.

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.
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.
HestiaPi is ready for makers, hackers, and developers. Because it’s open source, you can:
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.
If HestiaPi is funded, 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.
Use HestiaPi’s attractive touchscreen to control the device.
HestiaPi has an easy-to-use, touchscreen interface.
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 during the crowdfunding campaign, we will donate at least €1 to openHAB Foundation e.V.

All parts are sourced from various European and Asian suppliers and delivered to Athens, Greece. All crucial parts are subject to unit testing. Stock, PCB assembly, product assembly, and order handling is in Athens, Greece. All finished products are run through a final quality audit.
We face two main risks and challenges in manufacturing and delivering HestiaPi Touch: low throughput of 3D printing enclosures and components delivery delays.
The largest potential manufacturing bottleneck is in the 3D-printed case. Any hiccup here will slow down the delivery of pledges that require a case (not all pledge levels require a case). We’ve mitigated this risk by having already successfully tested two separate 3D printing houses. We will use the fastest and cheapest (located in Greece) and, if something goes wrong, we will switch to the alternate factory until the primary factory is operating to our standards.
Regarding parts delivery delays and losses, we have three ways of protecting against these affecting delivery to backers. First, we will be ordering all parts from two different suppliers, both of which we’ve used before. This will increase the cost a little, but will save the day if one supplier’s delivery is postponed. Second, parts delivery will not be happening on a continuous basis, but assembly will, so we will stock up on all parts the first month of production and then assemble. At some point we will have enough parts and only assembly will slow down order delivery. Finally, we already have parts on-hand for around 50 complete orders.
If you have a technical question about the operation of the HestiaPi or any of its applications, please ask the creators your question directly on their forum using the link above.
Should the HestiaPi campaign succeed, we’ll work on additional hardware modules and kits that will work with your unit.
