Hi Saif
In Wellington, we are working with a major international firm who have developed an open, interoperable, programmable edge gateway for a wide range of IoT devices. The standard we are using is through Fiware (NGSI). We have focused on sensors to begin with, but looking at actuator devices also and the open standard approach has made interfacing with multiple suppliers far less of a problem. We're in a very promising position.
Our city council is committed to open standards and as far as possible, open data. The idea is that we purchase much of the technology in this area as a service, shielding us from risk of obsolescence and allowing us as an organisation to be agile in following new technologies. This is a conscious step away from big capital investment (and accompanying resource tied up in ever-shortening depreciation/amortisation cycles) in hardware and software solutions. We see this becoming more and more common, and lessening our reliance on 'closed' proprietary end-to-end systems which leave us at the mercy of a single supplier.

Subject: IoT Devices Required
I am building a generic system integration gateway to access/control IoT devices.
My problem is sourcing devices (switches, sensors, door bells etc) that can be configured/programmed to communicate with my gateway or allow my gateway to communicate with them (tcp/ip, ssl optional) over custom protocols or MQTT (I am also using Mosquitto and have interfaced with it using the eclipse paho C lib).
The IoT devices that I see advertised seem to be locked up to communicate only with IoT applications marketed by major vendors.
Are there any suppliers of open, programmable, configurable IoT devices? (for delivery to Sydney, Australia)
Thanks and rgds
