Selected work
Self-hosted energy-monitoring portal
A private dashboard turning live inverter and battery telemetry into cost insight and alerts.
Problem
Off-grid and hybrid power setups expose plenty of telemetry but no usable view: no history, no cost model, no warning before a battery bank degrades or the grid drops.
Approach
Inverter and home-automation telemetry is ingested on a fixed cadence into a time-series store. A role-gated portal renders dashboards, computes a two-zone, DST-aware electricity tariff from the import series, and raises alerts on anomalies — all self-hosted behind authenticated access with a full audit trail.
Stack
Outcomes
- Continuous visibility into generation, consumption and battery state of health
- Automated day/night tariff split with no manual meter reading
- Status-change alerts delivered to chat within seconds of the event
- A single self-hosted portal in place of several disconnected vendor apps
