need some place in my craft box…

Due to moving completely to Xiaomi stuff I sell my old door sensors which worked fine until I replaced them.

Some are already sold. My last four I’m offering here. I have four pieces left. Two are brand new and two are used. The used ware modified with external lambda/4 self made antennas which brought more range.

My price for all is 15€ incl. shipment within Germany, but I can ship for sure in other countries with the appropriate surcharge.
I prefer PayPal, but classic giro transfer is okay as well.
