Automating our dual fuel towel radiator

As I explained in my earlier post, heating our bathroom, we installed a dual fuel tower radiator. A dual fuel radiator is one that can be heating by both our central heating and an electrical element inside the radiator. This allows us to dry our towels without having to turn on the central heating, something … Continue reading Automating our dual fuel towel radiator

Making a dumb light switch a little smarter

A few months back, when planning the rewiring of our house, we decided not to include any switched 5A sockets; you know the kind of arrangement where a switch on the wall can turn on some floor lights and lamps in a room? If you want light, but something subdued, it gives you an alternative … Continue reading Making a dumb light switch a little smarter

LED Clock, Update!

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!

LED Clock, Part II: Tick, Tock

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

Lockdown LED Clock

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

Do we have any hot water?

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?

Shelly 1 Relay

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

Den Automation and the Cloud

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

Xiamo Aqara Wall Switch

With news that Den Automation were likely going into administration (due to massive debt) and the discontinuation of their Cloud services, my dreams of adding more Den switches were well and truly dashed! I'd added a few Aqara temp sensors and contact sensors to my Home Automation setup and I discovered that they had a … Continue reading Xiamo Aqara Wall Switch

Den Automation – API

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
