For ESCOs and BEMS retrofit teams

Energy Proof

Before you ask a client to fund a retrofit pilot, prove the data layer is usable: which loads can be measured, which claims are still unsafe, and what hardware must be added next.

Check the claims See missing metering points

What can be used in a client diagnostic today?

Count only metering points that can support a first evidence pack: active kWh, live load, import/export, voltage, current, and missing bays that define the next coverage gap.

The page checks for a new snapshot every 30s. HA site readings are published by the local collector every 15 minutes.

Energy bill, not currency conversion.

Cost is estimated from public local tariff references. Each market can be viewed as commercial or residential; currencies are not converted into each other.

Using only period kWh currently available in the metering snapshot. Lifetime plug kWh is not treated as billable period energy.

What can a consultant safely claim?

The useful output is a claim boundary. It tells an energy consultant or retrofit integrator what is already measurable, what is only a weak signal, and what cannot be promised to a building owner yet.

Evidence question

Current state

Claim status

Risk

Next action

Continuous plug, circuit, and incomer power

Available

Usable for a stronger evidence pack

Short history window

Collect 7-14 day baseline with 5-minute buckets

HVAC energy evidence

Partial

Only controller-level view

No dedicated circuit meter

Add HVAC circuit meter

Data quality and duplicate detection

Visible

Useful for data QA

Duplicate/unavailable rows still exist

Exclude ghosts from active board

Panel / whole-site baseline

Available

Live baseline claimable

Import/export semantics need history

Verify 7-14 day import/export trend

Interoperability proof

SONOFF + Shelly + Xiaomi + IamMeter

Good early signal

Limited protocols

Add one wired/BMS data source when available

What must be added before a paid pilot?

Each missing point maps to a concrete next purchase or data source. This keeps the conversation away from vague platform promises and toward a scoped diagnostic.

SLOT 01

Baseline history recorder

The IamMeter incomer is now visible. The next gap is continuous 5-minute/hourly history, uptime, and import/export validation before site-level savings claims.

SLOT 02

HVAC circuit evidence

Dedicated metering for the AC or heating load so the demo can separate standby, runtime, scheduling drift, and weather-normalized anomalies.

SLOT 03

Occupancy and comfort context

CO2, occupancy, door/window, or business-hours proxy data to explain whether power changes are operationally acceptable, not just numerically lower.

SLOT 04

Tariff and carbon layer

Public local tariff references first, live tariff feeds later. Cost estimates must use city-specific electricity prices, not currency conversion.

SLOT 05

Reliability recorder

24/7 heartbeat and data-gap log per device: online rate, last seen, missing samples, firmware notes, and recovery time after a dropout.

SLOT 06

Report export

One-page readiness score, anomaly screenshots, device matrix, and retrofit point list that a facilities manager can use in a pilot review.

How this becomes a diagnostic pack.

A diagnostic pack turns meter coverage, load history, tariff assumptions, and missing points into a claim boundary a client can act on.

1. Observe

Collect power, energy, voltage, current, online state, and timestamps from installed meters at the representative site.

2. Diagnose

Score gaps: short main-meter history, duplicate rows, unavailable entities, weak HVAC boundary, missing occupancy context, and protocol coverage.

3. Package

Convert the evidence into a claim boundary, retrofit point list, and one-page report a consultant can use in a client discussion.

Start with one representative site.

The next useful step is a 7-14 day diagnostic: log the current points, validate import/export trends, add missing HVAC or occupancy context, and produce a claim boundary the client can review.
