Networks and security

Network design and configurationStructured, documented networks that stay easy to maintain.

I plan and configure switches, routers, firewalls and VLANs, and keep office, guest, camera and machine traffic apart. You get a working network, an IP plan and a configuration backup. Cabling is done by an installer; I can specify it and check it.

Wi-Fi coverageMeasured Wi-Fi coverage, not guesswork.

I measure signal and interference through the building, then place and configure access points, wired where possible. You get before-and-after measurements as proof.

Remote access and VPNReach your systems safely from anywhere.

I set up VPN access so cameras, controllers and files are reachable without opening ports. For industrial sites, vendor access can be per person, logged and time-limited. You get the setup and a short guide for adding or removing users.

Data security and backupBackups that actually restore, and fewer open doors.

I find out what is critical, set up backups (3-2-1) and test a real restore. I close common gaps: default passwords, open ports, old firmware. You get a short report of what was done and what remains.

CCTV and video surveillanceCameras that record what matters, and nothing more.

I plan camera positions and set up recorders, retention times and secure viewing from your phone without opening the system to the internet. Setups follow Swiss data protection rules, for example not filming neighbours or public ground without need.

Intrusion alarm and access controlAlarm and door access set up, tested, documented.

I configure alarm panels, detectors, keypads and access readers, plus user rights, schedules and notifications. Every zone is tested before handover. If your insurer requires a certified alarm installer, I tell you at the start.

Energy and buildings

PV, battery and energy managementMake solar, battery and loads work as one system.

I configure inverters, batteries, energy managers and meters so you use more of your own power and can see where it goes. For ZEV and LEG energy communities I help set up metering and the data needed for internal billing. Electrical installation and grid registration are done by a licensed installer.

EV charger integration and load managementCharge the car without overloading the house connection.

I configure the wallbox and link it to the energy manager to charge from solar surplus, and set up load management for several chargers. Installation and notice to the grid operator are done by a licensed installer.

Smart home and building automationLighting, blinds and heating that follow simple rules.

I programme and extend KNX installations in ETS, add logic and visualisation, and connect them to solar, alarm or heating. You get the documented project file, so you are not locked to one company. 230 V wiring is done by an electrician.

Industrial and control systems

Commissioning and site acceptance testsBring systems into service and prove they work.

I commission devices, controllers and software on site and test them point by point against the specification. You get a signed test protocol and a clear list of open items. I can write the test procedure or work from yours.

Device and protocol integrationMake devices from different vendors exchange data.

I connect meters, PLCs, sensors and gateways over Modbus RTU/TCP, MQTT or OPC UA, and check every value against the field. You get a tested data path and a documented signal or register list.

SCADA and control systemsMonitoring and control for distributed sites.

I configure and extend SCADA systems: signal lists, alarms, screens and communication to remote stations, and I find faults on fibre and fieldbus links. I also train operators.

Custom integration softwareSmall, maintainable software where no product fits.

I write gateways, protocol converters, data loggers and test tools in C#/.NET, Python or C++. You get the source code and documentation, and you own both.

Engineering support

Troubleshooting and field serviceFind the cause, not just the symptom.

I trace faults across network, fieldbus, devices and software, on site or remotely, with proper measurement tools. You get the root cause and either the fix or a clear recommendation. Also the second pair of eyes when vendors blame each other.

Hardware and PCB testing, test benchesTest boards and devices before they ship.

I measure and debug PCBs and build fixtures and automated test benches, scripted in Python with results logged per serial number. Fixtures and enclosures can be 3D-printed in-house.

Technical documentationDocumentation the next engineer can actually use.

I write as-built documents, network diagrams, IP and signal lists, test reports and operating guides. Your system no longer depends on one person's memory, including mine.
