Some Sonoff TH16 and Sonoff POW Manufactured in December 2016 / January 2017 Are Being Recalled

Sonoff TH16 and Sonoff POW are inexpensive and useful wireless switches based on ESP8266 WiSoC. I’m using Sonoff TH16 to control a water pump, and Sonoff POW to monitor my office power consumption. I received mine in early November 2016, so they were probably manufactured sometimes in October. Does manufacturing month matter? Yes, it does, as ITEAD Studio has just issued a recall notice for both devices for a batch manufactured between December 2016 and January 2017. The problem is that while the switches come with a 16A relay, the trace were not thick enough, and if you connect a device that draws enough power, they would heat enough to make the case slowly melt. The problem is that ITEAD Studio asked the factory to add “sufficient tin to the wires to ensure low enough impedances”, but they did not quantify it clearly, and that’s why the product is not […]

Intel Smartwatches are Hot! So Hot, They May Burn Your Skin

Low power in constrained spaces is a tricky business, even for ARM based SoCs with the Qualcomm 810 overheating saga a few months ago. Now it’s time for Intel to feel the heat, as the company has has to recall Basis Peak smartwatches / fitness trackers due to potential overheating causing skin burns. Josh Walden – senior vice president and general manager of the New Technology Group at Intel Corporation – stated: On behalf of the Basis Science team, I want to personally apologise for this situation, we know that many of you love using your Basis Peak watches and have made them part of your daily lives, and we are very sorry for the disruption this will cause you, we had hoped to update the software on your watch to address the problem, unfortunately, despite our best efforts, we aren’t able to develop such a solution without completely compromising […]

The European Version of Orvibo Wiwo S20 Smart Socket Has Been Found to Pose a “Serious Risk”

Orvibo Wiwo S20 is a WiFi smart socket that can be controlled by a smartphone and some people are using it with OpenHAB open source automation software. The socket has four versions with with US, UK, EU or AU plug types, and some of my clever readers mentioned that the European plug was mot likely NOT compliant with European regulations, was likely dangerous, and should be limited to 2.5A instead of 10A. It turns out they were right, as the European commission issued a safety notice last declaring Orvibo Wiwo S20 to be dangerous with risk of electric shock. The document further explains: The shape of the socket is not correct: when a plug is inserted the live pins of the plug are accessible. Appliances which should be earthed can be connected to the socket but the socket itself is not earthed. The product does not comply with the requirements […]
