Regular readers will know about the script that Aidan Ruff and I originally developed to put Node-Red and several other packages onto the Raspberry Pi for our own home control purposes. This has been developed with help from several people and in particular my friend Antonio “Mr Shark”. WELL –…

BigTimer
Node–RED is a fantastic and powerful yet easy to use programming tool for wiring together hardware devices, APIs and online services in new and interesting ways. For more information on Node-Red go to the Node-Red site. BigTimer is the the most powerful and best-ever, most comprehensive timing node for Node-Red,…
Handy Node-Red Date
While working on my thermostat I found myself repeating the same code all over the place – as I use function nodes for inline debugging and info – far more useful at times than the debug output. I’ve now attached this simple code here to a function in my init…
RFLink and Node-Red
A little while ago I went to stay with my pal Jonathan and he had some Byron doorbell pushes to play with. This article updated 09/11/2018 to fix negative temperatures He showed me a universal RF 433Mhz receiver board he purchased which could look at the signals from the various…
The Wall Display
This blog has been updated as I’ve discovered that these displays are, after all, still freely available from AliExpress. I’ve recently spent time working on my hallway wall display, an amount of time which would be considered commercial suicide. Good job it isn’t commercial. Of course I’ve not just been…
Waiting for Peter, closing out 2017
MrShark at the console, while we’re all waiting for Peter to come back, let’s try to add some new content to the blog 🙂 I’ve a couple of new boards to test, unfortunately they’ve to wait I receive their PSUs… material for an other time 🙂 So, I’ll add some…
Node-Red and Alexa with Big Timer
I’ve recently updated my setup at home, finally doing away with HA-Bridge and I thought you might like to see this simple setup. So for beginners, HA-Bridge is a piece of software (a very nice piece of software) that runs on for example a Raspberry Pi, who’s job (in my…
Graphing System Info in Node Red and Grafana
We were just talking about getting system info into graphs in the comments in a previous blog entry – and I realised I already had some code for getting that info in Python – and using a library that can provide a LOT more. So – as it was there…
More Alexa Marvels
Some of you may recall that in the dim and distant past, Aidan and I wrote a SKILL for Amazon’s Alexa – which let us do anything by simply passing the speech back to Node-Red… and we could sent text as speech to Alexa. Well, that relied on SSL port…
Node-Red BigTimer Example
I am constantly asked about using Bigtimer (node-red-contrib-bigtimer) and so here’s an example of how I am using it in conjunction with both Amazon’s Alexa (voice control) – and the Node-Red Dashboard.
Saturday Node-Red Sermon
I just learned something new! ONLY of interest if you are using Node-Red and will lead to a description of the new node-red-contrib-diode node. If you are into Node-Red – you really want to see this one…
Garden Data Collection
This entry is all about InfluxDB, Grafana and a cute little Bluetooth garden sensor! Some time ago a pal of mine and I did some swaps of spare kit and I ended up with a Mi Flora sensor. A rather pleasing looking device, the MI Flora has a 3v lithium…
