Updated August 07. 2016: This article which started off discussing the “new addition” of i2c to the home control software, is now NOT ONLY about an I2c 2/4 line LCD display facility recently added to the ESP8266 boards – but there’s a PARALLEL version as well, making use of GPIO…

Node-Red on a Phone
I have to hand ALL the credit to Dave at the Node-Red Google Groups for this – and you might want to pop any questions in that direction because I know even less about running Android at the command prompt than I do Debian! Running Node-Red on your Android phone…
Nextion Update
As you may know the home control software can work with Nextion displays and there is a project on the blog on that subject – I note that one or two people are having issues here so rather than reply without pictures – here’s a general update. Currently with the…
I2C Conundrums
Resolved – working though still don’t know why Arduino single write was causing problems – however – got a way around it. Firstly why am I doing this i2c thing? Well, the little ESP8266 is a wonderful thing but there are some chips out there that are really neat and…
Node Red Dashboard
As regular readers and fans of node-red will know, I’ve been a fan of node-red-contrib-ui for some time – I wrote about adding security to it some time ago and until Imperihome came to my attention I was developing pages based on this. But, sadly the fellow developing it ran…
WIFI Smart Socket
It looks like Itead have done it again – another winner – well that’s all down to the price and I’ll leave you to look that one up…the site says £9.76 for the unit which is reasonable – but I didn’t check postage. The first modern WIFI wall socket I…
ESP8266 Meets Arduino via I2C
If you’ve been reading the blog regularly you’ll know I added I2c to the ESP8266 code some time ago – that is, the ability to send an I2c message either to read or write – originally intended and still working with cheap I/O expanders – so you lose 2 wires…
Sunday Morning Experimenting
I figured after a couple of horrendous days figuring out what was wrong with my ROMS, it was time for a morning’s relaxing. Some time ago I added I2c to the Home Control software but never actually got around to doing anything with it. The i2c parallel expansion modules I…
ESP SDK and RBoot Woes
Remember I did an article entitles Serial Woes? Well that’s been changed to serial success as we found bugs in tools and gained an understanding of the USB FTDI handshaking lines – which altogether led to improvements in the Node-Red Arduino node and a completely working solution for USB Serial…
NanoPi M2
More from FriendlyArm – this time the NanoPi M2. I’ve had this board running both Debian and Android – but first – a little about the boards. Like the M1 these are small – around 65mm by 60mm so much smaller than Raspberry Pi. They are also cheaper than the…
Raspberry Pi Node Red Serial Delight
Or – how to get USB serial ports working on the Raspberry Pi This originally was a cry for help – I wanted a second serial port on the Raspberry Pi AND I made the mistake of trying out Firmata on the Arduino at the same time – resulting collection…
Chip First Looks
Right now I’m finishing up my installation on the little CHIP board – only to find that WEBMIN would not work – and why is that? Well, the entire WEBMIN site down and also this morning – SOURCEFORGE website was down!!! it’s back up now and webmin is now…
