Automatic (Online Coordination)
Uses TOMMY's cloud server for coordination between your TOMMY instance and devices. Most reliable option but requires continuous internet access.
TOMMY Flasher Only
Online coordination is only available when using the TOMMY flasher. For ESPHome devices, use Automatic (mDNS) or Manual instead.
Requires Internet Access
Both the TOMMY instance and devices need continuous internet access. Enable Online Coordination in Privacy Controls first.
Privacy Information
TOMMY communicates with https://coordination.tommysense.com when Online Coordination is enabled:
- When devices discover: Your TOMMY instance and devices use the coordination server to find each other and establish direct connections
- Ongoing: Periodically to maintain coordination state while devices are connected
Data transmitted: Only minimal connection metadata (such as identifiers for pairing) is exchanged with the coordination server. Sensing data stays local on your network.
Verification: You can verify the network calls and payload using tools like Wireshark with a TLS intercepting proxy such as Fiddler.
How It Works
Uses TOMMY's cloud server for coordination between your TOMMY instance and devices. Most reliable option but requires continuous internet access. Devices and the server coordinate through the cloud, then connect directly. Sensing data stays local.
When to Use
Use coordination when:
- You have internet access and want the easiest, most reliable option
- You prefer reliability over privacy
- You're on the same local network
- You prefer fully offline operation
