I studied your article (CoAP) in http://tools.ietf.org/html/rfc7228. we are developing Home automation Solution with IoT enabled devices.
I have following doubts to provide the seamlessly solution for Home Automation.
1. I have some appliance with Wi-Fi enabled controllers
2. These controllers are connected to One Standard Router (ex:- CISCO,TP-Link, D-Link). All appliance connected to one router through Wi-Fi.
3. These appliance controlled through local handheld devices by using our proprietary protocol with in the Home network.
Now, we want to give a one feature like operate these appliance by using Handheld device from Remotely.
Internet is enabled to this Router & also register one domain name. But our problem is how to send commands or data from remote devices through Internet to home appliances.
Note:-
1.I don’t want to develop or place controller between IoT devices & Remote handheld devices. 2. Request is initiated by remote handheld device only.
I hope, any body can guide to me for better solution.
Thanks in advance
