Home Automation and More, or HAM is a home automation system I and a collegue devised in 2015 using wireless technology and power electronics. I built most of the first working prototype, using an AVR microcontroller, ESP-8266 wifi module and a simple TRIAC driver circuit. The prototype is able to measure power consumption using an Allegro Hall effect current sensor and a voltage measurement circuit I designed.

For the software part I wrote a website in PHP, a mobile app utilizing Apache Cordova, a control server using nodejs and wrote the firmware in C.

We have moved a long way since then. You can check more about the system and it’s current status in the website
