PowerView® Installation guidelines

This guide should give you some advise for problem free installation of a PowerView® system. For a more step by step installation guide go here

Hub guidelines

  1. Do not place the hub in a metal box.

Metal is one of the best materials for blocking radio signals. Putting the hub inside a metal box or near a lot of metal will completely block the signal.

  1. Do not cover your hub with lots of wires

    Many times the hub will be installed inside an installation cupboard with lots of wiring running through. Wiring is made of metal and -as said- is very good at blocking radio signals. So clear the hub of cables running over, next, or beneath the hub.

  2. Place your hub in a central location or near the PowerView® blinds.

    The less distance a radio signal has to travel and the least amount of obstacles a hub has to penetrate the more reliable radio reception will be.

  3. Discover small groups of blinds one at the time.

    Performing a discovery using the app at a big installation can "flood" the radio signal: All blinds will respond at once to the hub possibly missing one or more signals. It is advised to power up a small group of (approx 4) blinds and perform a discovery. Then power up another group of 4 blinds (unplugging the previous group) and do a discovery. Repeat these steps until all blinds have been discovered.

Repeater guidelines

A repeater picks up any incoming wireless PowerView® signal and transmits it again at full power increasing the range of the signal being sent.

  1. Don't use more than 6 repeaters in an installation

    More than 6 repeaters will very likely cause interference of the PowerView signal deteriorating signal reception. If more repeaters are required either relocate the repeaters or use an access point.

  2. Preferably put repeater halfway between remote and blind.

    Make sure the repeater is both in range of the sender and receiver. There should be just enough overlap (see yellow parts in the image) in range between hub/remote and repeater:

    • Too much overlap will make the signals of hub, remote and repeater interfere and range extension is not optimal.
    • Too little or no overlap means the signal is not being received by the repeater.

  3. Install a repeater opposite to the blind.

    Place a repeater (or any other PowerView transmitting device) opposite to the receiving device or blind improving a direct line of sight. Avoid placing repeater on the same wall.

Blind guidelines

  1. Antenna clear line of sight

    If possible arrange the blind antenna to have a "clear line of sight" with the hub or repeater.

Signal loss at obstacle penetration

Signal loss when penetrating a building material is called attenuation. It is one of the many, but nevertheless one of the most important factors in predicting signal reach inside a building. Below values are given as an indication for assessing signal reach at a possible installation.

Ghost scenes

How a ghost scene can occur

Schematics:

ghost scenes

Scenes are stored in the motor using a scene ID (e.g. 3421). If the hub activates a scene it sends out a command "Activate Scene 3421". The hub has no notion which shades should be responding. The command is sent to all shades and each shade determines whether it has such a scene stored in its memory and chooses to act or not. A scene activating a shade which shouldn't respond to that scene is called a ghost scene.

A ghost scene can occur in different ways. But generally is (accidentally) created following these steps:

  1. Create a scene for shade 1.

    The shade receives a command from the hub to store a scene. This command contains a sceneID created by the hub (for example 3421) and position data (where to go to when the scene is activated).

  2. Unplug the motor and delete the scene from the app.

    The hub, the app and the user have no notion of that scene anymore. But the shade did not receive the delete command. So it still contains a scene with id 3421 in its memory.

  3. Create a new scene on shade 2

    The hub issues a store-scene command to shade 2. For this scene the hub uses the next available Scene ID which is the previously deleted scene with id 3421.

  4. Activate the new scene and watch both shade 1 and 2 respond.

    The hub sends out an activate scene 3421 command. Both shades have scene 3421 in memory. Shade 1 does now have a ghost scene.

Remove a ghost scene

There are several ways to remove a ghost scene. Depending on the situation one can choose to:

  1. Create and delete the scene.

    Compared to the other methods described below this is the most reliable method.

    If you encounter a shade with a ghost scene:

    • Explicitly add the shade to that scene by selecting Use Current Position. The hub now is aware of that shade having a scene with ID 3421.
    • Now remove that specific shade from the scene.

    The Ghost scene should now be gone.

  2. Sync shade memory.

    IMPORTANT

    • This currently does not work with the M25T-PV motor (Roller blinds/Twist® Roller Blinds) below serial number 0039365.

    From the app select shades from the main menu. Select the shade with the ghost scene and scroll to the bottom. Select Show advanced options and scroll to the bottom. Select Sync shade memory and confirm. The shade should not have any ghost scenes anymore.

    Please double check whether all scenes work as they should.

  3. Delete shade from app and do an 18 second reset.

    This will remove the shade from the app. Discovery, room and scene assignment need to be re-done.

    From the app select shades from the main menu. Select the shade with the ghost scene and scroll to the bottom. Select Show advanced options and scroll to the bottom. Select Delete shade and confirm.

    Press and hold the shade button for 18 seconds. The shade will jog after 6, 12 and 18 seconds. Release the button.

    IMPORTANT

    • Remove power from the motor by disconnecting the power cable from the battery wand or power supply and wait for 20 seconds.
      power down

    IMPORTANT

    • After 20 seconds Power up the motor by connecting the power cable to the battery wand or power supply. power up

The ghost scene should now be gone.
