How would my home react to me?

Lights and devices can be turned on or off depending on your presence. Your presence is determined by pinpointing the position of your smartphone. This smart home function, called indoor localization, is very new! You might have some questions on how this would work out in your home. That's what we will talk about in this post... How would my home react to me?

Beyond smart lighting

The possibilities in which Crownstone can help you to automate your home are very diverse. Crownstones can be used not only with lights, but also with other electronic devices. It allows you to add useful functions to devices such as fans, TVs, speakers, video game consoles, etc. Beyond smart lighting

Insight into the Crownstone App.

When creating our first two scenarios to automate our home, we used the Crownstone app and experienced how simple and straightforward this process can be. Now, we will provide a general overview of the Crowstone app and compare it with other smart home apps, so we can let you know why we are proud of our app. Insight into the Crownstone App.

The magic of Crownstone scenarios.

We sketch two scenarios that use the Crownstone capabilities around sunset and at night. The first scenario uses indoor localization. The second scenario makes your switch smarter at night. The magic of Crownstone scenarios.

Bluetooth for proximity detection.

The use of Bluetooth LE for contact tracing is not a panacea. There are a lot of factors that influence the signal strength and with that the distance estimates. Those are factors like phone orientation, multi-path attenuation or fading, obstructions, and many more. Bluetooth for proximity detection.

Firmware and hardware wizardry.

For a noob, the code on a device like Crownstone might look like magic spells; the programmer might look like a wizard including the long hair; the computer like a science-fiction console. However, did you know that as a firmware developer most of the time is spend on debugging!? Firmware and hardware wizardry.

Privacy matters.

When we enter a hotel room in a new country the small changes that normally get unnoticed suddenly get noticed. Dan Hill cites Timothy Morton: '*the light switch seems a little closer than normal, a little differently placed on the wall*'. Technology should be seamlessly integrated in our environment. Privacy matters.

iOS advertisements in the background.

Developers have a hard time to cope with iOS advertisements as soon as the app goes into the background mode. However, it is possible to scan for devices, it just requires more in-depth knowledge. iOS advertisements in the background.
