Hello.

I see a lot of discussion about "IoT" and seam some are already done.

I am a Hardware design , ok to write SW for AVR when I have understand what to do. 

can someone explain the connexion between a HW ( for example a Dimmer) a phone and why need internet?

I was thinking to use a BLE but seam all market have moving to Wifi .. But wifi means at you must go to internet. 

if you go to internet, your need some IP to connect or place ?

My idea is not to re invente the wheel.. finish with this but to make some product som will give more to customer and make some feature more the Scandinavia market than the low cost china product. 

Than means low volum , not 100000 pieces her. if this concept need to high invest than it is dead.

Thank you for guide or example

Thierry

The internet is usually needed as most people's internet is NAT'd (network address translated) so outside systems cannot connect unless the user sets up their router which is way too hard for joe average. So the devices connect via wifi then 'phone home' to a central server in the cloud somewhere. Then external devices connect to this server and can communicate to the home device. That way you can be anywhere in the world with your mobile phone and control your house.

 

The latest is voice control via Siri, Alexa or Google. Again, the home device connects to a central server. With Apple, you need an Apple crypto device in your system. You can only get this from Apple. I'm not sure of the others.

WiFi is not the same as an internet connection!

 

WiFi is a LAN, that is a Local Area Network and can function totally "off grid" with no connection to the internet.

On this WiFi LAN you can set up a web server, this server can even be integrated in your microcontroller and still doesn't need an internet connection! You will be able to access this web server from for example your smartphone as long as it is connected to the WiFi.

 

It's not rocket science, buy an arduino and one of the cheap WiFi modules and follow one of the many guides on how to set up a web server. I've done it once with a ARM developer board with ethernet and an external access point connected to it.

Nordic Semiconductor has a SDK for Bluetooth 5 to IPv6 via 6LoWPAN (router software connects 6LoWPAN to IP WAN)

ATSAMB11 and ATBTLC1000 recently made Bluetooth 5 (greater range, enhances mesh networking)

Bluetooth 5 is a fit for a house or a McMansion.

A .com (or .cc) can have a server that clients (customers' IP devices) can communicate with.

Lantronix - Global Device Manager on a server, device servers or device gateways, SDK for device gateways

Cloud - it's a plethora of servers to choose from; Microchip - Ubidots, Google, Amazon (more?); one reason why IBM is buying Red Hat (open source cloud)

Then it's EU GDPR as part of Scandinavia is completely in the EU.

Where's the customer's data stored?

Where's the customer's keys stored?

Others are asking the same question.

There's an effort to create an alternative to the Internet (Meganet)

An alternative is peer-to-peer over IP instead of client-server.

Thank all.

I see it is not like I was thinking.. or people want keep complicate. 

must make my own idee about that.

internet / server ++: I want not have for a lot of reason first  GDPR , security ++  and want at it working without internet anyway. 

Bluetooth 5  --> not see so much this

used ble4 a lot and see at it is not always stabil
