I've recently bought a new house. We completed renovated our first house and, in the process, we made an awful lot of mistakes. Don't get me wrong, we got an awful lot of things right too, but we've always had some annoyances. These were born of inexperience and naeivaty. With this new project, we have … Continue reading New House – Technology Choices
Back in February of this 2020 (This post has taken me a year to write!), I preordered an alarm panel from Konnected.io. The idea with the Konnected alarm panel is that you can take your existing wired alarm and connect it to your smart home setup. It's a very clever bit of kit, which I … Continue reading Installing Konnected Alarm
Whilst I await delivery of more WS2812 LEDs, I wanted to start investigating how I can leverage the Alexa Gadget Toolkit integration, so that when I set a timer using Alexa, my LED clock can show the countdown. Amazon make an Echo Wall Clock which does just that. I found an open source project called … Continue reading LED Clock, Part III: Alexa?
I managed to rework the time calculation and hour hand movement! https://videopress.com/v/jndhVFHI?muted=true&persistVolume=false&preloadContent=metadata The clock is ticking! I removed the RTC component and just let the loop run, with simple counters to simulate the passage of second, minutes and hours. I think the transition of the "hands" needs to be smoother, more analogue. I'll have to … Continue reading LED Clock, Update!
In Part I, I covered the basics of controlling the LEDs. This covered the hands of the clock. The second part of my investigation covers time and how to make the clock tick. The ESP 8266 I am using for this prototyping work doesn't include a Real Time Clock, so I was required to add … Continue reading LED Clock, Part II: Tick, Tock
A year or two ago, I picked up a WS2812B LED strip, but, for the life of me, could never think of anything useful to do with it. Recently, however, I came across these LED powered clocks. https://youtu.be/5c7LYEAVJHg https://www.youtube.com/watch?v=4ZatJAPwI_4 https://youtu.be/JNpjX5mobfI This feels like a project that will combine a few things: ESP MCUReal Time ClockWS2812B … Continue reading Lockdown LED Clock
A common occurrence in our house is bath time. Another common occurrence is not having enough water for afore mentioned bath. Our hot water is provided by a system boiler/unvented cylinder arrangement and I use a Nest to control the hot water (more on that later). The current schedule has it running the boiler for … Continue reading Do we have any hot water?
With Den Automation facing immanent demise, I've been looking at alternatives. I came across the Shelly 1 relay, quite by accident, whilst looking at some Sonoff stuff. It immediately piqued my interest, mostly because it taught me that I didn't know anything about lighting circuits in the UK. I've installed my fair share of lighting … Continue reading Shelly 1 Relay
A few months ago, Den Automation Ltd appeared to drop off the face of the earth. My hub disconnected from the internet and the Den app would only work whilst I was at home. I should point out that I invested in Den via Seedrs. Continued Operation is possible I took time to try and … Continue reading Den Automation and the Cloud
With the very sad news that Den Automation is having financial troubles, I decided it was time to revisit my investigation into the protocol that Den uses. I had read on their website that they used both a cloud based and local network approach. In fact, this was one of the things that appealed to … Continue reading Den Automation – API
