VELUX ACTIVE with NETATMO is compatible with all VELUX electrical windows and accessories (window openers, roller shutters, awning blinds, interior blinds and Venetian blinds) using the io-homecontrol wireless conmmunication protocol. 
Additionally, is offers compatibility with selected Somfy electrical facade products (vertical roller shutters, vertical awning blinds, vertical interior blinds and vertical Venetian blinds) using the io-homecontrol wireless conmmunication protocol.

As of today, VELUX ACTIVE with NETATMO is only compatible with Apple HomeKit. Integration with Google Home and Amazon Alexa is not supported currently.

If your gateway is already installed, you can find the MAC address in the VELUX ACTIVE app. Go to: Settings > Home management > Gateway > MAC address and look for the 12-character code: "70: ee :50: xx: xx: xx". If you haven't installed your gateway, you can find the MAC address printed on the back of the gateway. Look for the 7-character code in the format "g:xx:xx:xx" (the last part of the gateway serial number which is located on the 3rd line).

Some Wi-Fi networks are incompatible with the VELUX ACTIVE with NETATMO gateway:

  • Public and enterprise networks.
  • Networks that only use the 5GHz band.
  • Networks behind an authentication portal.

Make sure your smartphone is properly connected to a functional Wi-Fi network before beginning the installation.

Then follow these steps:

  1. Reboot the Wi-Fi router and smartphone.
  2. Check the gateway is connected to power (small wihite LED is on next to the mains cable)
  3. If you have any Wi-Fi boosters/repeaters in your network, make sure each available access point has a different name (SSID) and check that the gateway is being connected to the access point with the strongest signal.

If the above steps doesn't solve your problem, then you should check your router settings by connecting to the router's configuration page (refer to your router's user manual).

  • Update the router to its latest firmware version.
  • Set a simpler Wi-Fi password, without special characters.
  • Ensure there is no MAC filtering enabled on the router (or make sure the gateway is in the white-list).
  • Ensure access restrictions (parental control, etc.) are disabled.
  • Check if the router has a sleep function. If so, disable that function
  • Disable the Wi-Fi channel restriction (enable automatic selection), or select channel 1, 6 or 11.
  • Check that 2.4GHz is also enabled if the router is dual band compatible (VELUX ACTIVE with NETATMO can only connect to 2.4GHz networks). Try also to disable 5GHz.
  • Check that UPnP is enabled.
  • Try to replace the current DNS servers with Google's (Primary: 8.8.8.8 / Secondary: 8.8.4.4).
  • Check if your router has any firewall / port filtering. If so, open the 25050 port (TCP).

VELUX ACTIVE interpret it an authorized user and deems it safe to unlock the home when a control command is received from a remote control.

Measurements and automation

VELUX ACTIVE provides two main algorithms for the automatic control of your indoor climate. The two algorithms are:
 
1) A ventilation algorithm that automatically controls your VELUX INTEGRA® windows to regulate room temperature, humidity and carbon dioxide (CO2). The ventilation algorithm relies on indoor measurements made by your sensor and weather forecasts retrieved from the Internet. By using this information, the VELUX ACTIVE algorithm can decide whether ventilating the room will improve the indoor climate, or whether the window should remain closed because the indoor climate cannot be improved.
To ensure a constant supply of fresh air, the algorithm also has an air recycling functionality, that ventilates the room on a regular basis (every 1-6 hours) for a period of 5-15 minutes depending on indoor and outdoor conditions.
 
2) A sun screening algorithm which is designed to prevent potential overheating by rolling down window coverings to block out the sun when appropriate. The sun screening algorithm also relies on weather forecast information to make smart decisions based on indoor and outdoor conditions.
VELUX ACTIVE algorithms can be adjusted to meet your personal preferences. If you want to increase or reduce the sensitivity to the indoor climate parameters or you want to define an inactive period, this can be done by opening the app and locating: "Settings > Active Control”.
Outdoor weather data is used to adjust duration and to which extent the window opens during ventilation and to prevent the window from operating when no improvement of the indoor climate can be made. The weather data is also used to adjust sun screening products to prevent potential overheating before it occurs.

All VELUX electrical roof windows are supplied with a rain sensor to prevent the window from opening in case of rain. The window will automatically close if it starts to rain. If you ask it to open while it's raining, you will receive a pop-up with a warning. The rain sensor will always override any VELUX ACTIVE automation.

When the indoor climate sensor is installed and the control algorithms are activated in the app, VELUX ACTIVE will automatically control all roof windows and all sun screening products in the room.
VELUX ACTIVE will continue to operate during Internet outages. It continues to regulate the indoor climate and sun screening according to the latest set point applied before the outage (away mode, manual set point, etc.).
 
However, during the outage you will not be able to use the app (i.e. no product control, no reading of indoor climate parameters and no modification of any settings). App functionality is automatically re-activated on all connected devices when the internet connection is re-established. The gateway may take a few minutes to reconnect after the Internet connection has been re-established.
 
During a power outage, VELUX ACTIVE functionality will not available. You will, however, be able to control solar powered VELUX products using the remote control. When power returns, the gateway will automatically reconnect to your router and the cloud servers. Please note that this may take a few minutes.

VELUX ACTIVE is designed to provide automatic control of your indoor climate year-round. During the cold season, the algorithms will be automatically adjusted to prevent cold drafts. At temperatures below 2°C, the windows will not open automatically to prevent snow and ice from entering the room.

Note: For solar powered products that are not being charged sufficiently during the winter time (i.e. snow on the solar panel), there may be short periods of time when ACTIVE control will be unavailable due to battery discharge.

To ensure total security of your home, the VELUX ACTIVE gateway will automatically enter secure mode (away mode) after a power failure. This prevent windows from opening if a power failure is created outside the home by a malicious person.
Yes, you can use the app to define a period after which your window will automatically close (i.e. time-based bathroom ventilation). To define the period, press the timer icon in the upper corner of the room screen. At the end of the timer, the window will automatically close and VELUX ACTIVE will re-engage.
You can adjust the period when your window will automatically close to meet your personal needs. By default, the period is set to 30 minutes, but it can be adjusted to any value between 0 - 12 hours.
No. VELUX ACTIVE does not provide the opportunity to define a schedule for opening and closing of windows and/or sun screening products. If you are using VELUX ACTIVE on iPhone, you can create a schedule in the Apple Home app - please refer to Apple HomeKit support.
It is possible to disable or stop VELUX ACTIVE to avoid automatic control of your windows and sun screening products. Open the app and locate: "Settings > Active control" to turn off all ACTIVE control. Or keep ACTIVE control enabled in a specific room, or part of a room, by opening the app and locating “Settings > Active control > Room”.

Yes, it is possible to disable VELUX ACTIVE temporarily in one (or all) rooms to avoid the automatic control of your windows and sun screening products during the night. Open the app and locate: "Settings > Active control > Room" to define the operating hours for that room (i.e. 8am to 9pm). Repeat this step for each room.

Yes, it is possible to disable VELUX ACTIVE in one room while continuing to have automated control in another room. Open the app and locate: "Settings > Active control" and select the room in which you want to disable VELUX ACTIVE. You can now turn off all ACTIVE control for that room – or define the operating hours for the room.
The room temperature is measured by the indoor climate sensor. The temperature is measured every 20 seconds within the 0-50°C / 32-122°F range.
VELUX ACTIVE temperature sensor measurements that are different from the measurement of another thermometer in the room could be caused by an improper installation point. Check that the sensor is not placed in direct sunlight, above a heating element, behind a curtain, near an open window or door. Remove the sensor and move it to a different position.
Humidity is measured by the indoor climate sensor installed on the wall in your room. The humidity measurement is updated every 20 seconds and is measured within the range 0-100% with ± 3% accuracy.
The carbon dioxide (CO2) level of the room is measured by the indoor climate sensor installed on the wall in your room. The CO2 measurement is updated every 5 minutes and is measured within the 0-5000 ppm range.
If no sensor measurement values are displayed in your app, it may be due to a battery or communication issue.
 
First check the battery level of the sensor.
- Check the sensor battery level by opening the app and locating: "Settings > Home management > Room > Sensor switch > Battery level".
- Remove the batteries, wait a few seconds before re-inserting them and then check if the LED is blinking on the front face of the switch.
 
Then check the radio signal quality between the sensor and the gateway.
- Check the sensor radio signal quality by opening the app and locating: "Settings > Home management > Room > Sensor switch > Radio signal".
- Move the sensor closer to the gateway.
The rain sensor provided with your VELUX window (or motor kit) is connected directly to the motor control. No information is transmitted to the app when rain is detected and the window closes (rain detection is handled locally by the window opener). The VELUX ACTIVE app will only warn of rain if the window (motor) is opened while it's raining.

If some or all your sensor values are missing, then your sensor may be unreachable (this will be indicated in the app). Please check the sensor batteries and replace them if needed. If only your carbon dioxide (CO2) value is missing, but the humidity and temperature levels are displayed correctly, then wait for 5-10 minutes to see if a measurement appears. The CO2 level is only measured every 5 minutes and this may occur after a battery replacement.

If none of these actions have made the sensor values appear, then your sensor needs to be replaced.

Note: CO2 measures will not be displayed up to 12 hours after initial installation due to calibration of the sensor.

The sensor and departure switch have a typical battery life of 2 years under normal operation. The sensor and departure switch will remain fully functional up to 7 days after entering the low battery state.

HomeKit

Apple HomeKit is a platform that enables compatible products from different manufacturers to work together on iOS/different Apple products. Apple HomeKit enables you to control your VELUX products by a simple tap in the Apple Home app, by asking Siri (Apple's voice assistant) or automatically.
You can use Apple HomeKit to control your VELUX products through Siri (Apple's voice assistant). Use your voice to open your window, to roll down the blinds or to ask about the current air quality status of your Home. Apple HomeKit also enables you to create scenarios that connect your VELUX products and other HomeKit compatible devices.
If Apple HomeKit is not working with your VELUX roof windows, check your data synchronisation:
- Unplug (power off) the gateway for at least 30 seconds and plug it in again.
- Wait for the iCloud synchronisation to finish on all connected devices using the same Apple account.
 
You can force synchronisation, by connecting your iPhone to the charger and restarting it. If this doesn't work, you will need to reset the HomeKit configuration and connect it again.

If you have already configured HomeKit with another iOS device, please refer to the FAQ: "How do I share the control of Apple HomeKit?" to get an invitation.
Otherwise, follow the below steps:

First, reset the HomeKit pairing of your gateway:

  • Remove the gateway from the Home app in case you see it in your Home app.
  • Verify your smartphone is connected to the same Wi-Fi network as your gateway.
  • Verify that your gateway is powered and that no LED is blinking at the back the gateway.
  • Press and hold the button marked with the gear icon.
  • When you see the LED blink red, release the button and press it once again quickly to confirm the reset.
  • The gateway will now reset and reboot automatically.
  • Wait until the LED at the back of the gateway glows in white.

Second, reconfigure the Wi-Fi access of the gateway:

  • Open the VELUX app and select "Settings"
  • Select "Home management"
  • Select "VELUX Gateway"
  • Select "Setup Wi-Fi" and follow the instructions.

Finally, pair your gateway with HomeKit:

  • Open the VELUX app and select "Settings"
  • Select "Home management"
  • Select "VELUX Gateway"
  • Select "Setup HomeKit" and follow the instructions.
HomeKit relies on a secured local protocol provided and designed by Apple. Apple HomeKit requires you to be at home and connected to your Wi-Fi network. VELUX ACTIVE considers this safe and unlocks your home when an Apple HomeKit command is executed. It is only possible to access HomeKit when you are away from home, if you are using an Apple home hub (such as an Apple TV or an iPad).
 
Note: Be careful using HomeKit automation when you are away from home, as this could result in your home unlocking.
To control your products with Siri and Apple HomeKit when you are away from your home (not connected to your home Wi-Fi network), you need to set up a device as a HomeKit home hub. This can be:
 - An Apple TV4 with tvOS 10 or later.
 - An iPad with iOS 10 or later.
You can use Siri voice control by pressing the home button, by pressing the side button or by saying the phrase: "Hey Siri". To use the "Hey Siri" command on your device, you must activate it by entering: Settings > Siri & Search > Listen for "Hey Siri".
 
Tip! When naming your rooms and products, you should be careful not to use the room type within the product name, as this can cause a naming conflict. Keep room type names (Bathroom, Kitchen) for the rooms and product type names (Window, Blind) for the products. This will provide optimal integration with Siri (Apple HomeKit) voice commands as well. If you are using English language for Siri (for best voice recognition), you should name your rooms and products with English terms for best performance.
During VELUX ACTIVE setup, you will be asked to scan the HomeKit setup code with the camera of your device.
 
The 8 digit Apple HomeKit code (xxx-xx-xxx) can be found on:
- The label at the back of your gateway.
- The last page of the Quick Start Guide provided in the packaging.
 
You can also enter the code manually if you cannot scan it with the device camera.
 
If you did not configure HomeKit during the initial installation, simply do it by selecting: "Settings > Home management > Gateway > Set up HomeKit"
You can share control of HomeKit accessories with other people if they use iOS 10 or later and are signed in to iCloud.
 
To share control, you will need to be either at home or have a home hub set up in your home when sending an invite.
 
In the VELUX ACTIVE with NETATMO app locate: "Settings > Home management > HomeKit > Invite".
 
In the Apple Home app locate: "The "arrow icon" in the upper-left corner > Invite > Enter the person's Apple ID used with iCloud > Send Invite".

Yes, you can install the gateway using Apple HomeKit (and not the VELUX ACTIVE with NETATMO app). Please follow the instructions provided here.

Note: For these installations, you can only use the functionality provided by Apple HomeKit and the Apple Home app. The ACTIVE automatic algorithms are not included in Apple HomeKit and can only be accessed by using the VELUX ACTIVE app.

When resetting the HomeKit pairing of your gateway, you will remove:

  • The Wi-Fi connection between the gateway and your router
  • The HomeKit pairing of your gateway

The pairing to your VELUX products, sensor and Departure switch will remain unchanged. 

To perform a HomeKit reset: 

  • Press and hold the button marked with the gear icon
  • When you see the LED blink red, release the button and press it once again quickly to confirm the reset
  • The gateway will now reset and reboot automatically
  • When the LED blink white, your gateway is ready for a new HomeKit pairing
  • Open your Home app and add the gateway as a new accessory in HomeKit
You can update your Wi-Fi configuration in case you need to change your internet provider. 
To perform the Wi-Fi update:

- Press and hold the button marked with the gear icon
- Release the button when you see the LED blink in white
- Open the iOS settings of your device and open the “Wi-Fi” section
- Select your gateway in the “SET UP NEW DEVICE …” section 
- Follow the instructions to update the Wi-Fi configuretion
