So – having managed to get WordPress up and running on the P2 I thought it might be nice to step back toward the original plan and get some home control running. I like PHP so I thought that it might be nice to have a PHP page with some…

Raspberry Pi 2 VNC Error Message Solved
Today is getting better by the minute. I’ve been plagued with my new Raspberry Pi 2with a harmless but annoying message when remotely accessing it from my PC with UltraVNC. A box would pop up with GDIBUS Error.org freedesktop.PolicyKit1 Error.Failed:; An Authentication agent already exists for the given subject. …
Pi Stage 2
The NEXT hurdle in getting the Pi to be the central plank of a home control system – was to get emails working. I installed WordPress and of course the first thing I realised was that it would not send emails – a quick inspection – no SMTP folder… needs…
Raspberry Pi Permissions
As you’ll note elsewhere in the blog, I’ve been playing with WordPress (PHP/MYSQL etc) on the new Pi 2 – an hitting problems with permissions. Typical of a Windows users (I’m quite happy in CPANEL) the Linux commands mean very little to me and there’s enough to learn without taking…

Landing on two Feet
Sometimes I really do land on 2 feet. So the ESP/MQTT rig now appears bulletproof and in a timely fashion the Raspberry Pi appears just in the nick of time. All I need is an easy to use Mosquitto/Node-Red setup and …. what should appear but a link to this…
Raspberry Pi 2 Fast Enough?
The Raspberry Pi is a nice, cheap little computer but for me it has never been fast enough – I’m not interested in making another media server (I have a DISKSTATION which does that just fine) but as I’ve recently been working with MQTT in my home control setup, I…
