I know how to program IoT using Arduino; but I want some ready made portable IoT devices that do not need any programming at device side. Just I want to buy and add these devices to the network (after some configuration) and (by using documentation provided by company) write a controller logic to them.

For Example:

  1. A ready made MQTT thermostat connect to some broker and publish temperature on some topic. Someone can buy that thermostat install it and read that temperature using MQTT client.
  2. A ready made CoAP regular light that connect to some CoAP server, someone buy it replace his home lights with that and by sending some CoAP messages to that device using a CoAP client it can be turned ON/OFF.

Kindly share the company name or links (for REST/COAP/MQTT only), I tried searching and could not find anything except Rachio Smart WiFi Sprinkler (Docs)

The IKEA Trådfri lighting system is all CoAP based, you can find my write up on the protocol here

Belkin WeMo devices are all uPnP and SOAP controlled as well so another open/self describing protocol

    Can we write a coap client to send a message to that? Further more i think it uses Zigbee

    I've written a mqtt to coap bridge hardill.me.uk/wordpress/tag/tradfri for the Ikea system. Yes bulbs use Zigbee, but if you read the link, you'll see the gateway uses CoAP
