Son of Sonoff: $5 WiFi Wireless Smart Switch via hack a day

We’ve covered the Sonoff a few times–a very inexpensive box with an ESP8266, a power supply, and an AC relay along with a way to tap into a power cord. Very inexpensive means $5 or $6. The supplied software will work with several systems (including, recently, Alexa). But what self-respecting hacker wants to run the stock firmware on something with an ESP8266 inside?

[Tzapu] certainly didn’t. But he also knew he didn’t want to start from scratch every time he wanted to deploy a switch. So he built SonoffBoilerplate and put the code on GitHub. The code manages taking configuration (including network settings) using a web-portal, can update itself over the air, and integrates with Blynk and MQTT. If you don’t like that code base, there are other choices including one that has a failsafe reconfiguration mode.

Shared calendars are one part of an organized family

by Douglas E. Welch , techiq@welchwrite.com 206-338-5832 Reader/Listener Line As a parent with a school-age child, I often hear other parents bemoaning their disorganized existence. Along with the busy schedules of two working parents you might have art classes, karate classes, Little League, soccer and more. Add in more than one kid and organizing your life can quickly become a nightmare. This is exactly why one of my most important organizing devices is a shared calendar that reflects all the activities and events for everyone in the household...and I do mean everything. If someone -- is required to be somewhere -- at sometime, it goes into the calendar. If we are given a calendar that reflects all the events for a particular activity (say, Little League), all these events immediately go into the calendar, along with notations on whether we are providing the team snack, working in the snack bar, etc. Even events that occur anytime during the day, like family birthdays, and other rem
