I have 16 Wifi smarrt switches left over from a project - only one was tested (to ensure that they are stil lworking, like new), the others are brand new.
5 Euro per piece - 60 Euro for all 16 switches
Can be shipped within Portugal (shipment costs not included), pick up in Serta (you can inspect before you buy) possible, or I can deliver in the area around Figueiro dos Vinhos / Pedrogao Grande / Serta.
Works great with Tuya / Smartlife App
