TOMMY
Device Discovery

Automatic (Online Coordination)

Uses TOMMY's coordination service for the device to look up the TOMMY server's local address (e.g. 192.168.1.100:8547) by pairing code and establish a direct local connection.

Requires Internet on Devices

Online Coordination requires your devices to have an active internet connection. If your devices don't have internet access, use Automatic (mDNS) or Manual instead.

Privacy Information

When Online Coordination is enabled, your TOMMY server registers its local address (e.g. 192.168.1.100:8547) with https://coordination.tommysense.com. Devices look up the server using the pairing code only. No device identifier or device IP is transmitted. See the Network Communication section of the Privacy Policy for the full details.

How It Works

The TOMMY server publishes its local address (e.g. 192.168.1.100:8547) to the coordination service. Your devices look up the server's local address by pairing code and establish a direct local connection. All data flows directly between the device and your TOMMY server after that.

Configuring Devices
