App Help

The app itself is self-explanatory. However, if there are particular questions coming in we will use them to answer them on this page.

Apart from this list of questions, there is also a “Help” section in the app itself. You will find it in the app menu.

Open the Crownstone app, just in the general overview. Now power on the Crownstone (plug it in). Keep the phone really close and this means really close. You will see a blue icon flashing. This is the Crownstone discovered by the phone. Click on it and read the instruction for setup. After this procedure you are the digital owner of the Crownstone and you can decide who is allowed to use it.

Make sure that the Crownstone is powered and that your smartphone is really close to it. During setup mode the Crownstone transmits very quietly so other people cannot claim your Crownstone!

If the Crownstone still does not show up, you might want to try a factory reset procedure. This is a factory reset procedure that will clear all the data on the Crownstone. The state of the Crownstone will be subsequently as if was just obtained from the store. The process of a factory reset is described below.

You can enable dimming for particular lights in the app. Of course, do not try to dim something that is not a light. Also, not every light can be dimmed. A halogen lamp is like an incandescent lamp but with a much longer lifetime. If you dim a halogen lamp it gets the lifetime of an ordinary bulb. That would not be nice! Also, some LEDs cannot be dimmed. This depends on the electronics made by the LED manufacturer. If a LED can be dimmed this is normally stated on the packaging.

One basic concept the Crownstone app introduces is the sphere. A sphere is a loosely connected group of Crownstones, a little bit like a circle on Google+, a page on Facebook, or a list on Twitter. A very logical sphere is your home. Another logical sphere is your office. However, nothing prevents you from defining a sphere that is not confined to a single physical space. Access rights are defined on the level of a sphere. This makes it easy to give other people access to select groups of Crownstones that you own.

You have to enable the function for a particular Crownstone. Click on a Crownstone and swipe left. This will show you a tab to configure the Crownstone’s behaviour.

If you click on “When you enter the Sphere”, “I won’t do anything”, you can adjust the behaviour. For example you can have a light switch on when you enter the sphere. Note, that this is the proximity function with fewer than four Crownstones. If you have more than four Crownstones you can use real indoor positioning. Then it is possible to configure behaviour when you enter or exit a room!

One of the functions of the Crownstone is “tap to toggle”. By holding the smartphone very close to the Crownstone, it will switch its state from on to off and the other way around. It will even do this if the app is in the background. This means that you do not need to navigate to the right screen to flip the (digital) switch. Just hold it close!

If you cannot enable the “tap to toggle” function, make sure it is enabled in the app preferences.

If you enable the “tap to toggle” function, it is enabled per device type. For example, you can configure it at once for all floor lamps.

If you have four or more Crownstones in a single sphere, there will be an icon at the top-left that allows you to initiate teaching your home the rooms that are available. Each room gets a little sign that indicates that it can be taught.

It is important not to place the Crownstones too far from each other. They have to be at a maximum of 10-20 meters apart, preferably in adjacent rooms. Currently the indoor localization is disabled if not enough Crownstones are visible from the smartphone. The indoor localization needs to be trained by walking around in the room after pressing a big round button in the interface.

This is a known issue. The current version of the Crownstone plugs (not the built-in version) implements a filter that allows small amounts of current to pass through to the device that’s plugged in. Normally this is no issue, but nowadays ther are LED lights that are so efficient that they can still function using this tiny bit of current. The next version of the Crownstone plug will not have this behavior, but will be functionally completely equivalent.

Installation of the built-in Crownstone should be exactly as indicated in the installation manual included in every package (see also below). What is very important to do is to pre-bend the wires. Strip the wires at 7-9 mm. It can be at 7 mm if you have standard 2.5mm^2 wires of which the plastic fits snugly into the connector. You should not have thicker wires such as 6mm^2 (because these are meant for 32-40A appliances).

Note that the wire coloring is different in each country. More importantly, in your home the colors might be actually incorrect! Never rely on the colors!

It is always recommended to switch the live line. The Crownstone switches between 1 and 4. The connectors 2 and 3 are shorted internally. The numbering is as follows: (1) live to load (to the light), (2) neutral to load, (3) neutral from source (from the wall/grid), and (4) live/phase from source.

Due to security reasons you cannot always perform a factory reset. A factory reset is only possible the first 20 seconds after you have powered the Crownstone. After that initial period it will not be possible to perform a factory reset. You will have to cycle the power off and on again to perform a factory reset at a later stage. The factory reset option is a final resort. The option you will find in the application at the “Help” menu. Navigate to “What to do if…”, and “I need to factory reset a Crownstone”. You see there a button you can press: “Factory Reset”. In older versions of the app, factory reset was called “recovery” (e.g. “I need to recover a Crownstone”).
