# Thermostat Simulations

> Use the thermostat simulation endpoints to mimic HVAC mode changes and reaching a target temperature on sandbox devices to test your thermostat app.

## Endpoints

[**`/thermostats/simulate/hvac_mode_adjusted`**](./hvac_mode_adjusted)

Simulates having adjusted the [HVAC mode](https://www.seam.co/docs/capability-guides/thermostats/understanding-thermostat-concepts/hvac-mode.md) for a [thermostat](https://www.seam.co/docs/capability-guides/thermostats.md). Only applicable for [sandbox devices](https://www.seam.co/docs/core-concepts/workspaces.md#sandbox-workspaces). See also [Testing Your Thermostat App with Simulate Endpoints](https://www.seam.co/docs/capability-guides/thermostats/testing-your-thermostat-app-with-simulate-endpoints.md).

[**`/thermostats/simulate/temperature_reached`**](./temperature_reached)

Simulates a [thermostat](https://www.seam.co/docs/capability-guides/thermostats.md) reaching a specified temperature. Only applicable for [sandbox devices](https://www.seam.co/docs/core-concepts/workspaces.md#sandbox-workspaces). See also [Testing Your Thermostat App with Simulate Endpoints](https://www.seam.co/docs/capability-guides/thermostats/testing-your-thermostat-app-with-simulate-endpoints.md).
