A open and Closed sign for our space!

Use case

To make it easier for visitors to see that someone is in.

How it was made

Melan helped me out a lot and provided 99% of the code as i'm a n00b at Python.

Flok messed around with things as well (added a few bugs).

Code

• https://github.com/Tahtk3v/Nurdopen (python code)

• https://github.com/NURDspace/NurdOpen-ESP32 (esp32)

Sending a text to it (to use it as a ticker)

• mosquitto_pub -h mqtt.vm.nurd.space -t 'doorpixel/scroll' -m 'niet poepen bij de deur'

What/where

• docker instance on erratic (vm 100)
• /home/nurds/openClosedSign
• start via Portainer (see Erratic, look for "goofy_chatelet" in the list of containers)
• recreate: docker stop openclosesign && docker rm openclosesign && docker build --no-cache . -t openclosesign && docker run -d --name openclosesign openclosesign:latest

Known issues

• the ESP32 seems to lose connection with the network after a couple of hours if the space is closed [1]
