Getting Started

Connecting to a Zigbee Network

1. Power on your Heimdall Pro controller by plugging in a 24V DC barrel plug or wiring up the +- terminals.
2. When the device powers up it will automatically start searching for a Zigbee Network. To connect the device to a network, the target Zigbee network will need to be opened. For the Phillips Hue Bridge you'll need to open the Hue App and start searching for devices. The Heimdall Pro will require a Zigbee bridge in order to use all of it's features, but for limited functionality you can connect to your devices with the Sowilo DS App via Bluetooth.
3. When the Heimdall Pro successfully connects to a Zigbee network it will brightness cycle up and down 5 times. The device can now be controlled from your existing Zigbee network application.

Pair my device over Bluetooth

1. To pair your Heimdall Pro over Bluetooth you will need to download the Sowilo App from either the Google Play Store, or Apple App Store.
   

   
2. After installing the Sowilo DS App for Android or Apple, open the app where you are required to sign-in with a Google Account or Apple Account. An account login is required to limit access of firmware updates to account holders only.
3. For Android, the Sowilo DS App will ask for location permissions. The location permission is required to operate Bluetooth on your phone or tablet. We do not collect, store, or read any location data.
4. The top right Bluetooth icon should be red. If you click the button it will start searching for a nearby Heimdall Pro device that is in pairing mode. To put a nearby Heimdall Pro into pairing mode push and hold the button on the Heimdall Pro for around 3 seconds. A lighting strip connected to the Heimdal Pro will turn blue to notify the user it has been put into pairing mode. The device will be in pairing mode for 2 minutes. Your Sowilo DS App should ask for permission to pair to the device.
5. In order to Bluetooth pair to specific devices, you'll need to navigate to the top right menu, and click into devices. This screen will show you all your paired devices, and will allow you to search for all nearby devices. In the nearby devices screen, if a Heimdall Pro is in pairing mode, the light-bulb icon will be blue. Click on any nearby devices that are in Bluetooth pairing mode.

Advanced Configuration

Configure a single Heimdall Pro device

1. Open the Sowilo DS app, after pairing a device via Bluetooth, click into Devices from the top right menu. Swipe left/right to find the device you would like to connect to. After connecting to a device, you can press "Identify" to see the lighting strip you are currently connected to.
2. Press into configure, and you'll find options "Congure PWM", "Power on Behaviour" and "Power Mode". Navigate into the menus to adjust the single device's configuration options. The light will brightness cycle up and down on a successful adjustment of an option.
3. To keep your device up to date with the latest firmware updates click "Update Device". If there are updates available, the update process will start. Firmware will be downloaded and then uploaded onto your Heimdall Pro controller. Upon successful completion of a device update, your controller will power cycle. Avoid powering down your device while updating. Power cycling the device during upload will not harm the controller, but it could harm the device after the upload is complete and the firmware update commences.
4. From the Devices screen you can click into the "Lighting" option for a subset of lighting options. For full lighting configuration you will need to control the device via a Zigbee network.

Configuring multiple Heimdall Pro devices

1. Open the Sowilo DS App, if the Heimdall Pro you are Bluetooth connected to, is part of a Zigbee network, with multiple Heimdall Pro devices, you will be able to issue broadcast configuration commands to all your devices. From the main home screen, click "Configure".
2. From this screen you can click "Update Devices". This will initiate the update of the device you are Bluetooth connected to. After that device updates, it will broadcast to other Heimdall Pro devices on your Zigbee network, and they will start updating. Devices will power cycle off/on after a successful completion of an update.
3. If you click into "Rooms and Zones", you'll be able to select a grouping to issues broadcast configuration commands. By default you will only see the "All" option. If you are using your Heimdall Pro devices on a Phillips Hue Zigbee network, you should enable Hue-Connect. From the main home screen, click into the menu in the top right, click into "Settings". If you go into "Device Settings" you will find the option to enable "Hue Connect". With "Hue Connect" enabled you'll see your Phillips Hue groups from which you can issue broadcast configuration commands.
4. After selecting a group or zone, you'll be able to "Configure PWM", "Power on Behavior", and "Power Mode". If the group or zone is a Phillips Hue group or zone, the "Phillips Hue Scene Calibration" option will be available.

Heimdall Pro Options

Configuration

• Pulse Width Modulation (PWM)

The pulse width modulation frequency (PWM) is the frequency for which LEDs are oscillating in their on/off states. A high PWM will give higher quality light with less flicker, but at higher frequencies the duty cycle depth for low level dimming diminishes. So the pulse width modulation frequency will be a trade off between low level dimming and higher quality light.

• Power On Behaviour

The power on behaviour specifies the behaviour of the Heimdall Pro after power cycling. The default is a warm full white maximum brightness state. The last-on will set the light as the last colour before powering off but if the light was previously off, when power cycled it will be in the on state. The power loss recovery option will keep the exact state as before the power cycling. If the lights were off it will still be off after power cycling. Custom allows to choose a colour and brightness following a power cycling event.

• Power Mode

This option allows for toggling between an Optimized mode and a Lumen Maximizing mode. The brightness of the higher lumen color settings will be limited in the Optimized Mode, but the brightness output of low power color settings will not be scaled down. This allows for a reduction in power supply while not sacrificing the brightness of the lower lumen colors. In the Lumen Maximizing mode the brightest colors draw maximum power.

• Phillips Hue Scene Calibration

The Phillips Hue Scene Calibration allows for your Heimdal Pro devices to adjust colors when switching scenes in the Phillips Hue app synchronously. The Philliips Hue ecosystem doesn't take kindly to third party Zigbee devices; they purposely cause third party lights to "water-fall" when switching scenes. Enabling this feature will allow for all your device to adjust scenes at the same time.

Device Updates

• Select my Light Model
  

Sowilo DS has a number of different lighting solutions. If you wish to adjust your lights you may need to adjust the light model which requires firmware to be uploaded onto the device. Their is no broadcast configuration for updating light models. To adjust a controller you will need to individually connect and update.
