This one is only for Raspberry Pi / Node-Red fans. ALL SORTED – everything works – so this is here merely to help others and maybe to encourage a better setup for I2C, RPI GPIO in Node-Red 1.0 official, serial and SQLITE3? Here’s a thing – don’t even THINK about…
Node-Red Persistence
How could I POSSIBLY be so SLOW? For many months, after originally coming up with my own mechanism for making Node-Red variables persistent across power cycling – and then promptly forgetting about it, I’ve been conveniently ignoring the relatively new official way to do this… This morning, just out of…
Xiaomi Mi 4 Smart band
On the surface of it the Xiaomi Mi 4 looks like it’s predecessor, the Mi3, but it is NOTHING like it. The original was/is a fine, mono display smart band which my wife LOVES, but the Mi 4 is a full colour model while still retaining the best part of…
RPI4 Network Lesson
Updated September 20, 2019 This blog entry covers a wide range of issues I’ve had and resolved since the introduction of the Raspberry Pi 4 single-board computer (SBC) and the “Buster” update to the (Linux Debian-based) Raspbian operating system. Enjoy, technical readers using the RPI may find this very useful……
ESPURNA and SONOFFS
The reason for the title is simple – I’ve just had my first (favourable, exciting, even) experience with Xose Perez’s multi-purpose Espurna IOT firmware on some of my Sonoff power controllers. Regular readers will know that I developed ESP-GO and usually flash either ESP-GO or Theo Arends’s Tasmota firmware onto…
Photo Apps
It just occurred to me that the sub-title of my tech blog infers anything to do with gadgets – and most sunny summer days I find time to take photos, usually of gadgets but also of friends, scenery and local events. I do have a blog for photography – a…
Shelly One WIFI Switch
“Shelly One” is just one example of several (claimed) open source products produced by a company called Shelly who are based, not as you might expect in China’s mega technology city of Shenzhen but in Sofia, Bulgaria. Shelly are not new and there are plenty of videos out there about…
The Script
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”.
Sonoff BasicR3 10A
I’m currently blogging about the more expensive 16A Shelly One power controller and already this summer I’ve written about the Gosund units, but regular readers will be aware that I’m a long-term fan of Sonoff and their various low cost controllers. My most recent acquisition is a pair of Sonoff…
Cubot X19 Budget Phone
Updated August 17 2019: The Cubot X19 smartphone arrived back in May, well packaged, complete with USB charger and lead (the ad describes charging as Type-C fast charge and with its own charger it does charge quite quickly) and the first thing that came to my wife’s attention was the…
Gosund Smart Sockets
A pair of Gosund SP1 16A (i.w. 16 amps) Smart sockets turned up for me today. These German smart sockets plug into your mains power outlet and allow you to control the output either locally or remotely by a variety of means. Now, first off the bat these are not…
MobaXterm Pro
Some time ago, William Taur of Mobatek sent me the latest Pro version of their MobaXterm product, and very nice it is. Mostly in the past I used the excellent WinSCP but then I started using the free version of MobaXterm with great success. Excellent as it is, if you…
