Sunne likes to hang in front of a sunny window. It captures the sun-rays during the day and glows after sunset (when this is set in the Sunne app). Here is a quick explanation of how to hang your Sunne. Start by selecting the window that catches the most sun during the day. If you’re in the Northern Hemisphere, the best orientation is south. But depending on the location, east to west can also work. Sunne should not be too shaded by trees, or by the window frame. Sunlight must be able to reach the solar surface on the back. The instruction manual that comes with the Sunne, can be downloaded here.
A short press will switch Sunne on, another short press will set the next light mode. A long press (about 2 seconds) will put your Sunne to stand-by mode. Holding the power button for 3-5 seconds will put Sunne in the bluetooth pairing mode.
With the power button on top of Sunne, you can cycle through 3 different modes: sunrise, sunlight and sunset. Download the Sunne app and pair to your Sunne to unlock more features; your Sunne can automatically switch on at sunset, and you can monitor the charging performance and battery level.

You can either charge your Sunne with solar energy by hanging the Sunne in a window with the solar panel facing south. Make sure the solar panel is not covered. Or charge by USB-C using a suitable charger and cable (check following questions).
Use a 5V-2A charger with a suitable USB-C cable (USB 3.2 or higher) that is rated for a minimum of 2A. We have tested many chargers and found this one to be very easy and reliable: LINK In the Sunne app you can check the charging current. The higher the current, the faster your Sunne will charge. Consider swapping the USB adapter or the cable to increase the charging performance. For example; charging with 500mA will take your sunne a long time to fully charge. 1000mA to 1500mA will reduce the charging time by 2 or 3 times.
This really depends on the charger that is being used, but when charged with a 5V -1500-2000mA it will take up to 4-5hrs to fully charge.
This really depends on the charger that is being used, but when charged with a 5V -1500-2000mA it will take up to 4-5hrs to fully charge. When your Sunne battery is fully charged, the orange indicator light on the side will start blinking.
With a fully charged battery, Sunne can glow for more than 14 hours. This means it can still glow for you even on a cloudy day. Each evening, Sunne will use some of this stored energy when the automatic sunset is switched on in the app. Then the next day, if the sun shines, Sunne will generate energy to top up the battery level again. This is Sunne’s self-sufficient energy cycle, powered by the sun.
In Summer, temperature can be an important factor – some windows get really hot – so we suggest not hanging Sunne directly against the window. It’s best to leave at least a 2cm gap, to allow some cooling airflow. Above 45 degrees Celsius, the charging performance is limited for safety reasons. So if you see a lot of sunlight shining on Sunne, but it is not charging well, check the temperature. In Winter, sometimes there may not be enough sunshine to charge your Sunne sufficiently, especially if you like to use the light a lot during the day. Consider giving it a charge through USB C then.
To generate energy, sunlight must reach the solar surface on the back of Sunne. So, check if there’s any obstacles shading Sunne from the sun, like the window frame or a tree. The way solar panels work, even partial shading can have a massive impact. Adjust Sunne’s position to avoid shading. Besides that, if it’s a cloudy day, Sunne’s solar panel will generate less power. Consider giving it a charge boost using a USB C charger. In the Sunne app, more information is available about the battery status and how well Sunne is charging through the solar panel.
This depends on how much sunlight it catches, but when it is charging with 1500-2000mA (you can see the this current flow in the app) it will probably take about 4-5hrs to fully charge your Sunne.
Check in the Sunne app if Sunne is charging by tapping the battery icon below the slider. The pop up shows the charging current. It might say Current: 0. If your lamp is on, any solar energy harvested will go directly to powering the lighting, instead of charging the battery. So, it’s best to enjoy Sunne’s glow after the sun sets.
Of course solar panels need bright sunshine, but they actually don’t perform well when they get too hot. Plus, Sunne’s charging performance is limited above 45 degrees celsius for safety reasons. So, make sure you don’t hang Sunne directly against the window, but leave a some space for cooling airflow. When Sunne is cooled down enough, it will return to its normal state.
When the charging led is blinking, this means your battery is full. If the charging led keeps on blinking, turn your Sunne off and on again. This should solve the problem.
The battery level is too low, so Sunne switches off by itself to save energy. Consider putting Sunne in the sunlight, or charge with a suitable USB-C charger.
Did you know that Sunne is intelligent? How brightly it glows corresponds to its battery level, to maximize the length of time it will glow for. So, if it’s not getting enough sunlight, consider giving Sunne a boost charge through USB-C to enjoy it at full brightness. If the battery level is between 10%-20%, Sunne will be less bright to save battery life.
Go to the app store or google play store and search for Sunne Solar or click here for the iPhone app and here for the playstore app. Install the app and make sure that ‘Location services’ for the Sunne is switched on.
If you use the app for the first time, the app will guide you through the steps. Moreover, press and hold Sunne’s power button for over 5 seconds until the lamp starts flashing blue. Now your Sunne is in pairing mode and can be connected to your phone.
Make sure your bluetooth and wifi/5G is switched on and your Sunne is charged. A low battery will make it hard to connect to Sunne. Make sure you are in close proximity to your Sunne.
Go to the menu in the Sunne app (tap the icon in the upper right corner) and tap: add another Sunne. The Sunne app will search for Sunnes in your surroundings.
You can add up to 8 Sunnes to your Sunne app.
You can add up to 8 devices to 1 Sunne. We recommend you to not connect more than 2 devices to your Sunne, to make sure it keeps on operating smoothly.
Go to the menu in the Sunne app (tap the icon in the upper right corner) and toggle ‘Switch on at sunset’ on. Make sure you have your Location services switched on in your phone settings for the Sunne app, so the app can define your location and calculate the sunset time.
Here are our top tips to solve this:
When the Sunne does not respond to any input through the power button or the app, you can factory reset the Sunne, meaning it will reboot the Sunne and remove all saved data. Before proceeding with the factory reset, first remove your Sunne device from the bluetooth list on your phone, after that remove the Sunne app (either iOS or Android). Then proceed with the actual factory reset by holding down the power button for 30 seconds, until Sunne starts flashing red. Now the Sunne will reboot and is ready for reconnecting. After the factory reset, reinstall the app and pair your Sunne to your phone by going through the usual steps.
Yes, open your Sunne app, go to the menu and select: update Sunne. If there is an update for you to download to your Sunne, it will show you. If your Sunne is up to date, it will state: your Sunne has the latest firmware version!
