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

Set extractor fan to automatic – Part 1

A few months back, after we discovered mould growing on our bathroom ceiling, I replaced the wall mounted extractor fan with an in-line model, mounted in the loft. I never grasped how important the position of the van was in relation to the source of steam and the source of fresh air. Without going into … Continue reading Set extractor fan to automatic – Part 1

Adventures in deep sleep with ESP8266 and a temperature sensor

One of the small ESP8266 projects I did was the creation of a simple temperature sensor. I build a simple circuit, following the guidance from the following articles: https://iot-playground.com/blog/2-uncategorised/41-esp8266-ds18b20-temperature-sensor-arduino-ide https://www.instructables.com/id/IoT-Temperature-Sensor-With-ESP8266/ https://randomnerdtutorials.com/esp8266-ds18b20-temperature-sensor-web-server-with-arduino-ide/ I opted to use a probe on a long wire rather than using the little component. I ordered some of these from Amazon - … Continue reading Adventures in deep sleep with ESP8266 and a temperature sensor
