    What a great product. Super easy to use, and works fantastic. If you need an outlet (or two) to be controlled by anything that outputs an ac or a dc voltage, this is for you. I'm using it to run an inuke amp that is triggered from a 12v walwart plugged into the back of my home av receiver. Works perfectly. Turn on the receiver, that in turn sends a 12v signal (via walwart in switched outlet on back of reciever) to the IOT relay (which you plug into the green +- port on the IOT) which in turn sends full 120vac mains power to my inuke which I use for running my sub. Simple and fantastic. I can't just run the inuke amp straight off the switched outlet of my receiver because those are generally small amperage outlets, capable of 100-150w usually, not for running a power amp. I'll be ordering more of these as needed. Two thumbs up.

    Great product, but no always on socket, November 11, 2015

    This is a great product, well made an performs exactly as advertised. One thing to note if you are connecting a micro-controller to it, which is a use case they advertise: There is no always on socket. You can't plug your micro-controller into it for power, you need a completely separate power circuit.

    Extremely well made, solid, and totally hackable, January 5, 2016

    This review is from: Iot Relay - Enclosed High-power Power Relay for Arduino, Raspberry Pi, PIC or Wifi, Relay Shield (Electronics)
    Like others here, after buying the IoT relay and being completely happy with it, I decided that while the pair of relay controlled "Normally off" receptacles did exactly what I wanted, I did not want relay controlled "normally on" receptacles, I wanted "Always On" receptacles protected by the surge protector and controlled by the Off/Reset switch, but isolated from the relay and the signal.

    So, although I had been perfectly happy with the relay the way it came from the manufacturer, once I read a couple of the review here, I convinced myself that I just had to have some "always on" outlets, and yes, I could get this by just plugging the IoT Relay into a power strip, but I want a clean installation so I decided, about an hour ago, to hack it.

    This device is VERY well made. It has a robust circuit board, solid components, and it is laid out and assembled so cleanly and logically, that it is almost trivial to hack it. You have several options:

    1) You can alter it so that all four outlets give the same behavior, controlled by the state of the relay. This requires you to cut a circuit board trace to isolate the receptacle you plan to alter from the relay, then solder in a jumper to connect the hot sides of that receptacle to the hot side of the other receptacle. If you have made Arduino or RaspberryPi circuits of your own design and own a soldering iron, doing this hack will be completely trivial for you, you will open up the case, break out the Dremel tool, soldering iron and a piece of #14 wire, see EXACTLY what you need to do, and be done with the job just as soon as your soldering iron is hot enough. If you can't open the case and almost immediately grok the simplicity of this hack, you should button up the case, stop reading, and wait for the next version of this IoT relay.

    2) You can also change either set of outlets to be always on, regardless of the switch position or the state of the relay. This bypasses the surge protector and circuit breaker and is probably a BAD IDEA so you are on your own, I'm not going to tell you how to do this.

    3) You can wire either pair of outlets so that they are always on but controlled by the switch and protected by the surge protector and circuit breaker. This is probably the easiest option and the most desirable one. You simply solder a jumper wire from the common hot to the normally closed side of the relay and that's it.

    Once you open the case, you should easily be able to see the wiring traces that go to the neutral sides of both outlets. All the neutrals are bound together, and they all go back to the neutral side of the power input receptacle. You don't touch any of these and you don't mess with the ground either. The alterations will all be made to the hot side, so follow the hot side of the power input and see how it leads to the circuit breaker and surge protector components and to the common side of the relay. Then separate, hot traces go from NC and NO sides of the relay to their respective outlets. This board is so cleanly and logically laid out, that if you can't look at it and almost immediately see how it works, button the whole thing up exactly the way it was before you opened it because you are not yet ready to be playing with AC.

    I'm serious here, home gamers, if the hack is not completely obvious to you on first glance, then you really need to brush up on some theory, and practice on some low voltage circuits first.

    IoT nailed it, November 1, 2015

    Everyone is talking about IoT, devices, protocols, cloud, applications but it’s very difficult to find a single book which does justice to this subject. Everyone seems to have their own agenda for IoT.

    The author knows his stuff in and out and does a great job explaining enterprise concepts, the architecture, uses cases minus the technical jargons and keeps it simple. The last chapter of the book talks about implementing applications using AWS, Azure and IBM IoT which is very well explained. The security configurations for AWS IoT were very well explained and I was able t try out a sample even without a physical device. The comparison of cloud services at the end was really informative I was not able to find such information online. With just under 150 pages, this is the best good you could find on IoT.

    I would even say this book would be an essential contribution to everyone who needs to understand and build IoT applications and understand the big picture. highly recommended.

    The complete reference, November 4, 2015

    This is not a handbook, but a complete reference on IoT. Frankly, I bought this book initially as the price was under 10$, and thought the contents would be ok. But as I start reading the book, I was amazed with the information and quality of the content which even a 50$ IoT book couldn’t convey.
    I am an IoT architect and my job is to compare and bring out the best IoT offerings based on client requirements. I have been looking for details which shows how to build IoT applications using various offerings and this book has all covered. The best part about this book is that is explains everything you need to know about IoT, concepts, architecture, solutions, use cases, cloud offerings. Will wait for author next revision, I would like to see author cover more platforms like ThingWorx etc.

    Great primer on IoT and excellent how to guide, November 30, 2015

    The book is a great primer on IoT and an excellent guide on how to use cloud services from IoT platforms to build applications. The book is very well organized, it has 3 parts – the first part lays the foundation of architecture, devices, platforms, analytics, cognitive, solutions, protocols etc.. and also covers emerging standards like AllJoyn and show where the industry is heading.The second part is about use cases, coming from m2m and manufacturing background, I could easily relate on the manufacturing phases and move towards the Industrial IoT . The third part of the book is about how to build solutions by using cloud services - analytics, real time streaming, time series databases, device sdks etc.. from platforms like Amazon, IBM and Microsoft and even open source like kakfa, cassandra, spark etc.
    My only negative comments are:
    1. There are few typos in the book which sometimes come in the way of great content. I would recommend authors to proof read this thoroughly and get this corrected.
    2. The comparison chart didn’t render well on kindle, although there was a link provided which worked over the web.
    3. The product names for AWS IoT have probably changed and match those with latest one.
    I recommend this book along with "Abusing the Internet of things" book which talks about security aspects in detail for implementing IoT.
