Wil je slimme meter uitlezen, maar vind je een kabel van meterkast naar PC of Rapsberry Pi onhandig?

Kies dan voor de P1-wifi gateway.

Deze kleine module wordt via een kort kabeltje aan je slimme meter (Landis + Gyr E350 DSMR4, Kamstrup, ISKRA, kafia, enz) gekoppeld.

Power adapter inpluggen en gaan. De meterwaarden worden nu iedere 10 seconden via WiFi verstuurd naar waar je maar wilt. De meterwaarden kunnen ook via een webinterface worden uitgelezen.

Typische toepassing van dit setje is in een Domoticz installatie. Onmisbaar in elk domotica project! Alle slimme meters worden ondersteund.

Limesurvey on a Raspberry Pi (3b)

Image

TILT’s application server, Vortex, might give up after years of trusty service. So, I thought it an interesting experiment to if we could move our stuff to a Raspberry PI.
It took some effort, but I’ve managed to get it up and running. Amazingly cool.

Here are the rough instructions. I have just installed limesurvey250plus-build160228.zip on a brand new Raspberry Pi 3b. Works like a charm.

start with NOOBS on a new SD card
Boot up the Raspberry and have it install NOOBS.

Once up and running start up the terminal

sudo apt-get install apache2 -y —force-yes
cd /var/www/html
sudo chmod 777
.

sudo apt-get install php5 libapache2-mod-php5 -y —force-yes
sudo apt-get install mysql-server php5-mysql php5-gd —force-yes

create MySQL root passwd when asked for by the installer
(you will need this when installing Limesurvey)

sudo apt-get install php5-mysqlnd -y —force-yes

download limesurvey from limesurvey.org
(My version is limesurvey250plus-build160228.zip. Replace by whatever you actually download)
mv /home/pi/Downloads/limesurvey250plus-build160228.zip /var/www/html
unzip limesurvey250plus-build160228.zip

cd /var/www/html
chmod -R 755 /limesurvey/tmp/
sudo chown -R www-data /limesurvey/tmp/
chmod -R 755 /limesurvey/upload/
sudo chown -R www-data /limesurvey/upload/
chmod -R 755 /limesurvey/application/config/
sudo chown -R www-data /limesurvey/application/config/

cd /var/www/limesurvey/application/commands
php console.php install limeadmin pwd123 Admin admin@mydomain.com

replace pwd123 and mailaddress with your own data

In a browser window goto
localhost/limesurvey

The Limesurvey installer should now run

Presto. Enjoy!

Raspberry Pi Zero

Image

I’ve neglected the site for a while. That will change, starting now.

Raspberry org dropped the bomb 2 days ago, it’s called the Raspberry Pi Zero. I have ordered one immediately. The price indeed is 4 pounds sterling! (Including cable set (required only for the my first one) and shipping to the Netherlands, it cost me 19 Eur).

Start of the real computer revolution? Maybe. Computers sure are coming down in size.

THIS IS A GENERIC BRAND VIDEO.

BY KENDRA EASH

– – – –
We think first
Of vague words that are synonyms for progress
And pair them with footage of a high-speed train.

Science
Is doing lots of stuff
That may or may not have anything to do with us.

See how this guy in a lab coat holds up a beaker?
That means we do research.
Here’s a picture of DNA.

There are a shitload of people in the world
Especially in India
See how we’re part of the global economy?
Look at these farmers in China.

But we also do business in the U.S.A.
Or want you to think we do.
Check out this wind energy thing in Indiana,
And this blue collar guy with dirt on his face.
Phew.

Also, we care about the environment, loosely.
Here’s some powerful, rushing water
And people planting trees.
Our policies could be related to these panoramic views of Costa Rica.

In today’s high speed environment,
Stop motion footage of a city at night
With cars turning quickly
Makes you think about doing things efficiently
And time passing.

Lest you think we’re a faceless entity,
Look at all these attractive people.
Here’s some of them talking and laughing
And close-ups of hands passing canned goods to each other
In a setting that evokes community service.

Equality,
Innovation,
Honesty
And advancement
Are all words we chose from a list.

Our profits
are awe-inspiring.
Like this guy who’s looking up and pointing
At a skyscraper or a kite
While smiling and explaining something to his child.

Using a specific ratio
of Asian people to Black people to Women to White men
We want to make sure we represent your needs and interests
Or at least a version of your skin color
In our ads.

Did we put a baby in here?
What about an ethnic old man whose wrinkled smile represents
the happiness and wisdom of the poor?
Yep.
