Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.

I use it as a media remote for my computer via infrared. IR sensor sends analog data to an arduino which converts it to digital and sends it to a raspberry pi which then invokes commands to control media on my computer by invoking rest apis on a “unified remote” server running on the computer.
Feeling impressed here...
If I want to have this, too: is there a kinda tutorial or quick-setup, or is it more like 6 weeks of tinkering? :-)
It actually turned out to be easier than I thought.
The infrared reader (arduino code) is based on
https://github.com/Arduino-IRremote/Arduino-IRremote
The code running on my raspberry pi was written in Java using spring boot which is probably overkill but I am more comfortable with java than python so I used
https://github.com/Fazecast/jSerialComm
to read data from the pi’s usb port and just sent instructions to the unified remote server which does most of the heavy lifting. I used
https://github.com/openhab/openhab-addons/blob/main/bundles/org.openhab.binding.unifiedremote/src/main/java/org/openhab/binding/unifiedremote/internal/UnifiedRemoteConnection.java
as a reference along with some verbose logging on the unified remote server to see what codes needed to be sent over the rest api.
Happy to help you along if you want to give this a go :)
