Building technology
Building automation from someone who trained in both: the electronics and the software. Planned, programmed, integrated — wired or wireless, local instead of cloud.
Two ways into the house
A smart home is not a product decision, it is a question of timing. If the walls are open anyway, the line goes into the wall. If they are not, the signal goes through the air. Both roads reach the same place — only the intervention differs.
Wired · KNX
If the renovation is happening anyway, the installation becomes part of the house: a KNX bus runs through walls and floor, the actuators sit centrally in the distribution board. No dead spots, no batteries, a standard that has existed for thirty years — and will still exist in thirty more.
Bus topology — distribution board, line, actuators in the rooms.
Radio · Shelly, Zigbee, Matter
Where nothing gets chiselled open, the technology disappears into the back box: a Shelly behind the existing switch, sensors over Zigbee or Matter. The wall stays closed, the plaster stays intact. Reversible — rented flats included.
Radio topology — hub, radio links, nodes inside the back boxes.
Tooling
I am tied to no ecosystem. Whatever suits the house gets installed — and whatever refuses to talk gets a bridge.
Visualisation
Wall panel, phone, browser. Whether a Home Assistant dashboard or a purpose-designed visu: the controls are, in the end, the only part of the system a resident ever sees. Here they get the same treatment as any other interface built in this studio.
Bridges & data sovereignty
Heat pump, wallbox, inverter, alarm system — every device speaks its own dialect. A bridge translates: a REST endpoint here, an MQTT topic there, and in between logic that knows rules rather than clicked-together automations.
The hub runs inside the house. No vendor account, no cloud, no dependency on a server that gets switched off one day: the data never leaves the house.

Partner on site
When the installation goes into walls and floors, a plan is not enough. For renovation and construction work I collaborate with Coskun Fußbodentechnik — a Munich trade company whose website was also built in this studio. One contact for the electronics, one for the building work.

Qualification & limits
Trained as an Elektroniker in Munich: company, vocational school, guild, journeyman examination. The Gesellenbrief is on file.
Planning, programming, visualisation and integration come from me. Work on the fixed electrical installation I carry out together with a registered electrical contractor.
This holds for both routes — a Shelly in the back box is an intervention in the electrical installation too. I prefer an honest limit to a convenient omission.
A first conversation without sales pressure: the building, the timing, and what actually makes sense.
