# Device Simulations

## Endpoints

[**`/devices/simulate/connect`**](/latest/api/devices/simulate/connect.md)

Simulates connecting a device to Seam. Only applicable for [sandbox devices](https://docs.seam.co/latest/core-concepts/workspaces#sandbox-workspaces). See also [Testing Your App Against Device Disconnection and Removal](https://docs.seam.co/latest/core-concepts/devices/testing-your-app-against-device-disconnection-and-removal).

[**`/devices/simulate/connect_to_hub`**](/latest/api/devices/simulate/connect_to_hub.md)

Simulates bringing the Wi‑Fi hub (bridge) back online for a device. Only applicable for sandbox workspaces and currently implemented for August and TTLock locks. This will clear the corresponding `hub_disconnected` or `ttlock_lock_not_paired_to_gateway` error on the device.

[**`/devices/simulate/disconnect`**](/latest/api/devices/simulate/disconnect.md)

Simulates disconnecting a device from Seam. Only applicable for [sandbox devices](https://docs.seam.co/latest/core-concepts/workspaces#sandbox-workspaces). See also [Testing Your App Against Device Disconnection and Removal](https://docs.seam.co/latest/core-concepts/devices/testing-your-app-against-device-disconnection-and-removal).

[**`/devices/simulate/disconnect_from_hub`**](/latest/api/devices/simulate/disconnect_from_hub.md)

Simulates taking the Wi‑Fi hub (bridge) offline for a device. Only applicable for sandbox workspaces and currently implemented for August, TTLock, and IglooHome devices. This will set the corresponding `hub_disconnected` or `ttlock_lock_not_paired_to_gateway` error on the device, or mark the IglooHome bridge offline in sandbox.

[**`/devices/simulate/paid_subscription`**](/latest/api/devices/simulate/paid_subscription.md)

Toggle the simulated Nuki Smart Hosting subscription for a device (sandbox only). Send `is_expired: true` to simulate an expired subscription, or `false` to simulate an active subscription. The actual device error is created/cleared by the poller after this state change.

[**`/devices/simulate/remove`**](/latest/api/devices/simulate/remove.md)

Simulates removing a device from Seam. Only applicable for [sandbox devices](https://docs.seam.co/latest/core-concepts/workspaces#sandbox-workspaces). See also [Testing Your App Against Device Disconnection and Removal](https://docs.seam.co/latest/core-concepts/devices/testing-your-app-against-device-disconnection-and-removal).
