Network segmentation, firmware hygiene, and local-processing considerations for smart home setups — with notes on DSGVO-relevant data flows.
Read articleZ-Wave operates at 868.42 MHz in Germany, avoiding the congested 2.4 GHz band. Zigbee and Matter each serve distinct integration scenarios.
The Messstellenbetriebsgesetz (MsBG) mandates smart meter rollout for German households above 6,000 kWh/year. IoT layers can extend this data further.
IoT devices on flat home networks create lateral movement risks. VLAN segmentation on routers like Fritz!Box isolates automation traffic effectively.
Home Assistant and Zigbee2MQTT run entirely on-premises. Local automation reduces cloud dependency and keeps household data within the home network.
The Matter protocol (released 2022) enables cross-ecosystem interoperability between Apple HomeKit, Google Home, and Amazon Alexa devices over a single standard.
KNX, developed partly in Germany, remains the dominant wired automation standard in professional installations. Its association is headquartered in Brussels.
This site documents publicly available technical information about smart home systems as they apply to German residential contexts. Content draws on official protocol specifications, regulatory documents from Bundesnetzagentur and BSI, and manufacturer documentation.
