We recently were in communications with Frank Cunningham on his Tilt Fermentatorium, a Raspberry Pi app than not only shows a dashboard but can also provide alerts and notifications as well as control the popular KASA smart plug to keep your brew at the perfect temperature. For more information on how to download and install on your Raspberry Pi visit: https://github.com/RabbitFarmer/fermentatorium Check out the short summary and screenshots below. Happy brewing!

Take the Guesswork Out of Fermentation
The Tilt Fermentatorium turns your Raspberry Pi into a full-featured fermentation monitor and temperature controller. Whether you're watching over one batch or managing three fermenters at once, Fermentatorium gives you real-time gravity and temperature data, automated temperature control, interactive charts, and instant alerts — all from a beautiful web dashboard accessible from anywhere on your home network.

✅ Key Features at a Glance
Capability Details

Multi-Tilt Monitoring All 8 Tilt colors (Black, Blue, Green, Orange, Pink,
Purple, Red, Yellow) — standard, Pro, and Mini-Pro models

3 Independent Temperature Controllers Simultaneous heating and/or cooling for up to 3
fermenters using TP-Link Kasa smart plugs

Live Web Dashboard Real-time gravity & temperature display — use with a monitor or go fully headless

Interactive Charts Gravity trends, temperature history, and heating/cooling events powered by Plotly

External Logging Post data to Brewer's Friend, BrewFather, or any custom endpoint on a configurable interval

Push & Email Alerts Pushover, ntfy, or SMTP email — 11 configurable notification types

CSV Data Export Download batch and temperature-control logs for offline analysis

Remote Access Secure browser-based access via Raspberry Pi Connect — no VPN or port forwarding needed

Privacy-First All config, batch data, and logs stay on your system — nothing tracked remotely

🔔 Smart Notifications (11 Event Types)
Never miss a critical moment in fermentation:
• 📉 Fermentation Started — gravity drops 0.010+ points confirmed across 3 readings
• 🏁 Fermentation Complete — gravity stable (±0.002) for 24 hours
• 📊 Daily Progress Report — scheduled summary of gravity changes
• 📡 Tilt Signal Lost — alert when your Tilt goes quiet (configurable timeout, default 30 min)
• 🌡 Temperature Out of Range — alert when temp exceeds your high or low limit
• ❄   / Heating & Cooling Events — optional alerts when plugs switch on or off
• 🔌 Kasa Plug Failure — notified immediately if heating/cooling equipment goes offline
All notifications include smart deduplication and automatic retry with exponential backoff (up to 3 attempts).

🌡 Flexible Temperature Control
Configure each of the 3 controllers independently:
• Heating Only — one Kasa plug per fermenter
• Cooling Only — one Kasa plug per fermenter
• Heating + Cooling — two Kasa plugs, automatic midpoint switching
• Safety Shutoff — temperature control stops automatically if the Tilt signal is lost

⚡ One-Command Install
Getting started takes a single command on a fresh Raspberry Pi OS:

curl -sSL https://raw.githubusercontent.com/RabbitFarmer/fermentatorium/main/installer/automated-install.sh | sudo bash

Then open your browser to http://<your-pi-ip>:5001 — that's it!
