Monitoring ESG KPIs with IoT & Dashboards – Real-Time Impact at Hoyo Tech
Copy linkAt Hoyo Tech, we believe ESG is not a checklist — it’s a living, measurable system. With hundreds of IoT data points across our offices in Skopje and Struga, we’ve built a real-time monitoring infrastructure that not only drives automation but also tracks our ESG performance with transparency and precision.
In this article, we’ll show how we use Prometheus, InfluxDB, and Grafana to measure our environmental, social, and governance goals in real time — and how these dashboards help us drive continuous improvement.
📡 From Sensor to Dashboard – How the System Works
Every sensor, device, and system across our smart offices is integrated into a central data pipeline, structured as follows:
- Devices → Data Collection
➡️ IoT sensors (Shelly, Aqara, Xiaomi, Enphase, etc.) generate continuous readings
➡️ Data is normalized through Hoyo Smart and pushed to Prometheus + InfluxDB - Data → Aggregation & Storage
➡️ Metrics are time-stamped and tagged by room, function, and zone
➡️ Energy, air quality, user activity, automation events, and access logs are all indexed - Storage → Visualization
Grafana dashboards display key ESG metrics using:
➡️ Gauges
➡️ Time-series graphs
➡️ Role-based access logs
➡️ Heatmaps for environmental comfort
🟢 Environmental KPI Monitoring
Metric | Tool Used | Description |
---|---|---|
Energy use per sq. meter | InfluxDB + Grafana | Tracks real-time vs. expected consumption |
CO₂ and AQI compliance uptime | Prometheus + Alertmanager | % of time air is within comfort thresholds |
Solar vs. grid ratio | Enphase API + Prometheus | Daily/weekly breakdown of clean vs. grid energy |
Water usage (irrigation) | Sensor probes + Grafana | Moisture- and forecast-aware automation visualization |
🔵 Governance KPI Monitoring
Metric | Tool Used | Description |
---|---|---|
Access log traceability | Grafana Logs | Full audit trail with roles, timestamps, outcomes |
Automation transparency | Genera rule ID logs | Shows origin and condition logic for each action |
AI learning suggestion stats | Genera + DB | Tracks acceptance vs. rejection of AI proposals |
Compliance status per audit type | Custom PromQL | PASS/FAIL indicators for Automation, Access, Data |
📊 Example Dashboards
We’ve developed department-level and C-level ESG dashboards. Here are some panels included:
- Real-Time Carbon Offset Tracker
➡️ Live CO₂ savings based on local energy grid profile and solar output - Energy Leaderboard
➡️ Per-room and per-department consumption breakdowns - Comfort Heatmap
➡️ Environmental scores across zones, updated every 5 minutes - Governance Integrity Score
➡️ Combines audit trail completeness, override ratios, and rule transparency
ESG Monitoring in Action
Here’s how this plays out daily:
- Facilities team receives a morning digest with KPIs and comfort anomalies
- Executives can view ESG summaries before each board meeting
- Genera flags devices or zones outside KPI compliance, triggering real-time interventions
Looking Ahead: Automated ESG Reporting
In our next phase, we’ll:
- Introduce automated monthly ESG reports sent to stakeholders
- Benchmark our performance against international sustainability standards
- Expand KPI tracking to client deployments using Hoyo Home platform
Up Next in the Series…
In the next article, we’ll reflect on what we’ve learned so far — the real-world results, surprises, and changes we’ve made along the way — as we prepare to scale ESG beyond our offices.
