Frequently Asked Questions
- What hardware do I need to run LoopString?
- LoopString runs on any Raspberry Pi 3B+ or newer (Pi 4 and Pi 5 recommended). You also need compatible sensors and actuators — temperature/humidity sensors, relay HATs, etc. The platform supports standard I2C, UART, and digital GPIO sensors out of the box.
- Does LoopString work offline or without internet?
- Yes. The edge-first architecture means your Node-RED automation flows and PID controllers run locally on the Pi — they keep working even if the internet goes down. Cloud connectivity is used for the dashboard, alerts, and remote access via Tailscale.
- How much does LoopString cost?
- LoopString offers a free tier for hobby and evaluation use. Paid plans start for small operations and scale to enterprise fleet management. Visit the pricing page for current tier details.
- How long does setup take?
- A basic sensor monitoring setup typically takes under 30 minutes: flash the LoopString SD card image, power on the Pi, scan the QR code in the app, and your device appears live on the dashboard. No SSH or terminal required.
- What integrations does LoopString support?
- LoopString supports Tailscale for secure remote access, Firebase for cloud sync, SMS alert notifications, and webhook outputs for connecting to external services. The visual Configurator lets you build custom Node-RED flows to integrate almost any hardware protocol (I2C, UART, Modbus, MQTT).
