Flow-it

The Flow-it integrationIntegrations connect and integrate Home Assistant with your devices, services, and more. [Learn more] lets you monitor and control your Flow-it ventilation system in Home Assistant.

Use case: You can control the fan speed, activate preset modes such as Auto or Boost, and automate your Flow-it ventilation system alongside other smart home devices.

Supported devices

The integration supports the following devices:

  • Flow-it VMC ventilation systems equipped with Wi-Fi connectivity.

Prerequisites

Before setting up the integration:

  1. Connect your Flow-it device to your local network.
  2. Locate the password and IP address (if setting up manually) on the physical LCD screen by navigating to Settings > Wi-Fi.

Tip

Automatic discovery via Zeroconf is recommended. When discovered automatically, Home Assistant configures the integration using the device hostname instead of its IP address, avoiding the need to set up a static DHCP lease in your router.

Flow-it can be auto-discovered by Home Assistant. If an instance was found, it will be shown as Discovered. You can then set it up right away.

If it wasn’t discovered automatically, don’t worry! You can set up a manual integration entry:

Host

Username

The username used to authenticate with the device API. The default username is api.

Password

The password displayed on the physical LCD screen of your device under Settings > Wi-Fi.

    • Description: Controls the fan state, speed (levels 1 through 5), and preset modes.
