To control my DIY smart thermostat, I’ve created a webpage where some content like the current temperature needs to be refreshed.

Below every post on my webpage there are share buttons displayed. Because I’ve recently joined mastodon, I wanted to include a “Share on Mastodon” button.

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.
