The idea is simple: if you ran into a problem, someone else probably did too. Ask here, and the answer helps everyone.I'll be reading every comment and updating this post with the most common questions and solutions directly — so it becomes a living FAQ over time.  📺 New here? Start with the video. I just released a full overview of Project Aura — features, UI, sensors, fan control, and answers to the most frequently asked questions. Watch it before posting — there's a good chance your question is already answered there.    💬 How to ask a good questionPlease start your comment with a category tag — it helps others find relevant answers quickly:[Assembly] — enclosure, wiring, connectors, pin swap  [Firmware] — flashing, web installer, settings, bugs  [HA/MQTT] — Home Assistant, MQTT discovery, dashboard  [Sensors] — SEN66, SFA30, CO, pressure, RTCAlso include your firmware version when reporting a bug or issue. It saves a lot of back-and-forth.  📦 GitHub — stay updatedYou'll need a GitHub account to keep your Aura up to date — here's why.I had limited time and a limited number of testers during development. Once all of you start running your Auras, new bugs will inevitably surface that I couldn't catch on my own. I'll fix them and publish new releases regularly. Each release will include a ready-to-flash .bin file for OTA update over Wi-Fi — no cables, no IDE. I cover the update process in the video and it'll be in the assembly guide too.To get notified when a new release drops: go to the GitHub project page, click Watch → Custom → Releases. That's it — you'll only get an email when there's something new, no inbox spam.Takes 2 minutes. Worth it.You can also download the GitHub mobile app — and yes, Aura can be flashed directly from your phone too. 📱👉 GitHub: https://github.com/21cncstudio/project_aura  📌 FAQ (Will be updated as common questions come in) 📧 Assembly Instructions: You should have received an email with a link to the assembly instructions ZIP file. As a backup, I've also uploaded it to the model files — click "Download STL/CAD Files" and you'll find the instructions archive there! 📧 STEP files: These STEP files can only be accessed through the crowdfunding project page. Pls go access to the crowdfunding project page: Fulfillment - click "Checkout Rewards". 🆕 SFA40 Formaldehyde Sensor Now Supported!I've added support for the DFRobot SFA40 — the successor to the SFA30!  ⚠️ Pin swap reminder: One connector requires swapping the power pins before assembly. If you skip this step, you may damage your sensors. This is covered in detail in the assembly guide — please read it carefully before connecting anything. 🔄 Back Cover Options: In the original enclosure print files, you'll find 4 different back cover variants. The difference is which optional sensors they accommodate (CO sensor and/or DAC module). Choose the back cover that matches the sensors you're using.  Questions, feedback, ideas — drop them below. 👇
