Front door: 3- or 5-point locking without automatic locking system?

Well, with wired solutions as well as with radio, you could control motor locks via relays. However, there are also complete solutions for radio. So Homematic, Z-Wave, Zigbee, and all sorts of other things.... - You can actually find quite a few devices on the market. These are usually screwed to the door from the inside, run on battery or rechargeable battery, and use the corresponding protocol.

Yes, I also meant a solution with relays. I am always looking for experiences there.

We will install an automatic lock from Winkhaus (BlueAV) and use the company eKey to control the whole system. This will allow the implementation of fingerprint, transponder, or whatever else.
