Lua Planter findings

The Lua planter was an indigogo campaign that delivered some devices but failed and was quickly abandoned by the original author.

The device needed the web app at https://luaplanter.com for configuration, but that site is down. By luck I have the PWA cached locally, so I can still access it. But I don't know for how long.

I have managed to extract some of the files from the PWA, which are available in the source directory. Notably sw.js is missing.

Generated QR codes

Some QR codes are generated from the PWA and decoded using the zxing.org decoder in order to try to reverse engineer the QR code generation.
