Solutions — Environmental sensors
LoRaWAN environmental sensors, with comfort indices already computed
EnerSync receives Elsys sensors from ChirpStack and The Things Network, keeps every metric as it is and computes at read time dew point, heat and discomfort indices, barometric trend and storm alert.
01 — What it solves
Beyond temperature
Every sensor metric, no fixed schema
Temperature, humidity, CO₂, TVOC, light, motion, occupancy, external probes, water leaks: a new sensor type shows up in the dashboard without a schema change.
Measured comfort, not perceived
Dew point, humidex, NWS heat index, Thom index, and with the pressure sensor enthalpy and wet-bulb: computed at read time, with fixed bands so a colour always means the same.
Two network servers, one identity
ChirpStack and TTN side by side: a sensor migrated from one network to the other stays the same device with all its history.
02 — How it works
How it works
01
Elsys sensors
ERS-2, ERS-2 Lite, ERS-2 CO2, ELT-2-HP, ELT-LITE with TLV payloads: indoor rooms, external probes, pulse counters.
02
ChirpStack or TTN
Integration through a queue or MQTT; if the network server codec is missing, the platform decodes locally instead of losing the reading.
03
Metric catalogue
Each key has label, unit, category, colour and chart type in one catalogue; diagnostic keys stay in the archive but out of the view.
04
Dashboard and API
List with category chips and network badge, small-multiples detail, comfort heatmap; metrics through the API in native units.

04 — Regulation and obligations
Air quality and comfort: what the standards require
Italian D.Lgs. 81/2008, Annex IV
Microclimate and ventilation in workplaces: temperature, humidity and air change must be kept adequate. One sensor per room turns the obligation into a measured series.
EN 16798-1
Indoor environmental input parameters for design and assessment: air quality categories also based on CO₂ above outdoor level. The platform's fixed bands make the category readable.
EN ISO 7730
Thermal comfort with the PMV/PPD indices: it requires measured temperature, humidity and other parameters. The derived indices (dew point, humidex, Thom) give an immediate reading from the same sensors.
Directive (EU) 2024/1275 — EPBD
Non-residential buildings: automation and control above the power thresholds, and devices for measuring and regulating indoor air quality in new buildings and major renovations, where feasible.
Indicative references, current at publication date: they do not replace a regulatory check for your case.
05 — Frequently asked questions
Frequently asked questions on environmental sensors
Can I use non-Elsys sensors?
The platform stores metrics as a schema-free blob, so another manufacturer is added with its decoder; the Elsys family is what is in the field today.
Are the comfort indices reliable?
They are standard formulas (Magnus for dew point, NWS for heat index, Environment Canada for humidex, Thom) with fixed bands; where a pressure sensor exists the real pressure is used.
What is the storm alert?
The barometric trend normalised to 3 hours: a rapid pressure fall beyond the threshold raises an alert, independent of humidity.
How do I integrate the metrics?
Through the REST API with per-tenant tokens: metrics come in the native sensor units, derived values are computed on the data read.
