MeterScope Competition Entry - Home Automation Redesign

I designed my current home automation system 10 years ago, at that time I was very new in electronics and things such as PCB manufacturing in low quantities was far more expensive than it is today, so, in order to keeps cost down, I decided to make my PCBs at home, used some cheap 8 bit microcontrollers, a cheap PC working as server and I managed to have my lighting, shutters and gates all controlled via a web browser making it possible to control them both from a PC or a smartphone.

The whole system has been working with very little problems during this time, but recently one of the boards broke down and I decided that it was an opportunity to redesign the whole system, have proper PCBs manufactured and get rid of the rat's nests from my distribution boxes.

The new system will address one of the most annoying problems with the current system that is the lack of feedback, that is not an issue when I’m at home, but when I am away, knowing if the gates are closed or the shutters are down is very helpful.

While testing such a system, an oscilloscope is one of the most useful tools to have, unfortunately, bench oscilloscopes, like the name implies, are meant to be on a bench, however, home automation system testing often needs to be done in loco, that is ok if you only need a multimeter but many times an oscilloscope is also required, having an HS608 Meterscope would make testing much easier since it combines a multimeter with an oscilloscope, and most important, it’s portable.
