Ok, first things first, the DW2-Wi-Wi door sensor is as it says, WiFi, not RF or Bluetooth (though it does use BT to setup with the eWeLink APP in the first place). I looked here on Amazon and read someone saying the device was almost impossible to pair – mine…

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…
Raspberry Pi Zero WiFi
I should have just entitled this “Raspberry Pi” as it keeps expanding (now covering the rest of the Pi boards – but keep reading).. as you will see, the title is a little restrictive given what we’ve done over the last few days. Friend Antonio over Italy and I (still…

Toying with HA-BRIDGE
Thanks to readers in here I’m having a play with HA-Bridge to act as a device gateway between my home control (generally ESP8266) devices and Amazon Echo. I’m only scratching the surface and haven’t gotten past “Alexa, turn X on”, “Alexa turn X off” and “Alexa set X to 30%” …
Instant Node-Red
Peter Oakes kindly made a video – you’ll see it in my last post – on installing Node-Red using my script. Well, I was in the process of watching THAT when (as you do) I got side-tracked and discovered a really wonderful online tool for testing out Node-Red instantly –…
Enter the Video
A friend of mine, Peter Oakes has a series of videos on Youtube covering a lot of the subjects we touch on in here. He’s been tackling my latest Raspberry Pi script – so for those who like their information in video – here’s the latest.
