Live systems
A privacy-conscious view into the energy and environmental systems I design, instrument and improve at home.
The values below are aggregated engineering metrics. They demonstrate acquisition, processing and reporting without exposing occupancy, schedules or personally identifying data.

COP is most useful as a trend rather than an isolated number. The longer summaries reveal seasonal behaviour and provide evidence for control adjustments.
Environmental sensing
Private live telemetry
Greenhouse telemetry
Distributed sensing turns changing growing conditions into data that can guide ventilation, heating and irrigation.
The useful system is more than a temperature readout: it preserves context over time and brings multiple environmental signals together.
Climate
Internal and external temperature
Air
Relative humidity trends
Growing medium
Soil-moisture monitoring
Live greenhouse values remain private. The portfolio shows the system’s purpose and interface without publishing household telemetry or linking the private automation host.
