Hi Felix,
Any chance you have old manual Gateway step by step installation instructions? They are no longer in https://lowpowerlab.com/guide/gateway/setup-software/
Mine stopped working all of the sudden (after running for 2 years) and I'm trying to restore it (I did some heavy customization so I'm afraid latest version might not work with my metrics file)...
Unfortunately I do not have any older versions. The documentation is kept up to date with the "current" distribution and Pi versions.
Found it (thanks Sparky for IM) ! :)

Yeah, the blog has some old posts with the setup stuff I created back when I came up with the very first version of the gateway node app and websockets.
But beware those are using old linux packages so you should always use the latest for security reasons.
Your welcome Lensdigital, glad to help!
