With java spring boot it’s easy the write a web application. Standard this web application will run on port 8080. On GNU/Linux, ports below 1024 are priviliged ports, so a normal user can’t run a web application on ports below 1024. So, I’ve set up nginx as a reverse proxy to make those web applications available on port 80.

For the smartthermostat I’m working on, I was looking for a way to get the outside temperature without placing a real sensor outside.

Today, I’ve upgraded the HD44780 LCD of my smart thermostat. The new display has a backlight which is better to read.

The past months I’ve been working on creating my own smart thermostat. More info is available at http://www.janwagemakers.be/jekyll/portfolio/smartthermostat.html and https://gitlab.com/jan.wagemakers/thermostat/.

In 2012 I’ve connected a TC74 temperature sensor with a Raspberry Pi and used a combination of a bash script and a web server to display the current temperature on a web page. Today, I’ve updated this setup. Instead of using a bash script, I now make use of Apache and PHP.
