Free, open source (MIT) tool to audit your own smart home devices. Run sudo iotaudit auto: it finds the devices on your network and shows who each one talks to, whether traffic is encrypted, open ports, UPnP port forwards and idle uploads, then grades each device A to F in a local HTML or PDF report. No account, no telemetry, everything stays local.
Free, open-source browser extension that shows the price per kg, litre or piece on grocery web shops and warns when a pack gets smaller for the same price. Works on Lidl, Carrefour, Albert Heijn, Mercadona, ICA and more. No account, no tracking.
