When to Use Multiple Devices
Multiple Raspberry Pi devices are useful when:
- You have separate physical locations (different rooms, buildings, or sites)
- You need more GPIO pins than a single Pi provides
- You want redundancy with primary/secondary failover
- You are monitoring different systems that should be isolated
Setting Up Multiple Devices
Step 1: Add Devices
Add each Pi through the Add Device flow. Each device needs its own claim token.
Step 2: Configure Each Device
In the Configurator, select each device from the device dropdown and configure its rooms, parts, and flows independently.
Step 3: Deploy Individually
Each device receives its own flow deployment. Deploy changes to one Pi without affecting others.
Device Groups
Organize multiple devices into groups for fleet management:
- Create groups from the Device Groups panel in the dashboard
- Assign devices to groups by location, function, or project
- View group-level summaries on the Fleet Overview dashboard
Multi-Pi Mesh Networking
For coordinated automation across multiple Pis:
- Primary/Secondary roles — Designate one Pi as primary for coordinated decisions
- RTDB sync — Devices share state through Firebase for cross-device automation
- Shared signals — A sensor on one Pi can trigger an actuator on another
Example: Distributed Grow Facility
- Pi 1 (Primary) — Climate control room with temperature/humidity sensors and HVAC actuators
- Pi 2 — Irrigation room with pH, EC sensors and dosing pumps
- Pi 3 — Lighting controller with schedule-based relay control
All three Pis share data through Firebase, and the primary Pi coordinates cross-system decisions.
Dashboard with Multiple Devices
The dashboard supports multi-device viewing:
- Device selector — Switch between devices in the header
- Fleet overview — See all devices at a glance with status indicators
- Cross-device search — Find sensors across all devices
Device Limits by Tier
