10002 Screens and controls

Intro There is no point in having a smart home if you don’t see interesting information or control things. The traditional way, ever since the concept of smart home came to be, is to have some sort of central control panel for everything. In today’s world, that would be a tablet. In my attempt to do that, I ran into the control panel horror. What else? In parallel to this, I thought about the idea… Continue reading

10002 Zen

Zen At some point I though about building the smallest PCB for a sensor node that I could. Hence, the ZEN was born. The PCB is small enough to fit on a holder of 2 AA batteries. Where I have only build a few of these. Here is one reading the soil moisture sensor on basil. Here is another one chilling in the fridge, reading a temperature sensor. And here is one replacing the alarm… Continue reading

10002 Motion sensors?

Motion sensor madness Picking the right one for my smart home project is not trivial. From left to right – Osram Nightlux, Ikea Molgan, Ebay sensors with sensitivity and timing adjusment (BISS001), smaller ebay sensor with no adjustment, another ebay sensor. As you can see I have looked at 2 different options: use a ready made sensor and fit it with a radio, or build my own. Ikea Molgan I hacked one a while ago –… Continue reading

10002 Progress

This article is part of my 1000² Smart Home project. Check out the Architecture and Software and then move on to Hardware. An most importantly, check the Lessons learned and why I did what I did. There are already some first results, connecting all parts of the system. Progress Finally, enough pieces of the puzzle are starting to fit together in my Smart Home project, so that I can have some end to end functionality: press a button here… Continue reading

10002 Architecture and Software

This article is part of my 1000² Smart Home project. Check out the Architecture and Software and then move on to Hardware. An most importantly, check the Lessons learned and why I did what I did. There are already some first results, connecting all parts of the system. Starting with a top down approach – what the system should do, it soon became clear that some devices will be custom and some will be off the shelf. Determining… Continue reading

10002 Software

This article is part of my 1000² Smart Home project. Check out the Architecture and Software and then move on to Hardware. An most importantly, check the Lessons learned and why I did what I did. There are already some first results, connecting all parts of the system. Intro There is plenty of software to use in home automation, but of course I decided to stay with open source and free options. In recent years there have been… Continue reading
