EnergyCAP vs MRI Energy (formerly eSight)
If you arrived here looking for Wattics against eSight Energy, neither of those products exists under that name any more, and the honest version of the comparison is between the two successors. The lineage on both sides matters, so take it first.
Wattics is gone as a product. EnergyCAP acquired it in August 2022, adding building and device level energy management analytics, and wattics.com now returns an HTTP 301 permanent redirect to energycap.com. Anyone evaluating Wattics should be evaluating EnergyCAP, and should ask explicitly whether the acquired analytics are included in the quote or licensed as a separate module.
eSight is now MRI Energy. eSight Energy Group Ltd, a UK company founded by Simon Durrant, was sold to the German private equity firm BID Equity in April 2018 and then acquired by MRI Software, completing 2 November 2021. MRI markets the capability as MRI Energy on its own product page, where the eSight name survives only in the archived acquisition headline. Third party review sites still index the product variously as eSight and MRI Energy, which makes reference checking genuinely harder than it should be.
So the real comparison is a United States utility bill accounting specialist against a UK originated energy monitoring platform now inside a large real estate software vendor. Both document utility bill handling, energy metering, carbon reporting, anomaly detection, dashboards and reporting. The divergence is in what surrounds that core.
EnergyCAP surrounds it with accounting. Bill auditing and approval before payment, account and meter tracking, campus chargebacks, cost avoidance and a general ledger export, plus facility benchmarking and ENERGY STAR benchmarking support. Worth being precise: that is support for ENERGY STAR benchmarking, which is a free US EPA programme. Automated filing or submission on your behalf is not supported by the available evidence.
MRI Energy surrounds it with connectivity and landlord economics. It has the best documented protocol support of any product reviewed in this category, naming oBIX, Modbus TCP over IP and OPC Historical Data Access explicitly, alongside IoT and building management system connectivity, with PI Historian ingestion evidenced in a case study. It also combines utility bill validation with tenant utility billing, which is exactly what a commercial landlord recovering energy cost needs and which most pure monitoring platforms do not do. ISO 50001 and Greenhouse Gas Protocol reporting support are named explicitly, specific enough to be useful to a certifying organisation.

The products
EnergyCAP
EnergyCAP
United States based utility bill management and energy, sustainability software vendor. Acquired Wattics in 2022, adding building and device level energy analytics. The vendor website blocked automated access during research.
Full profileMRI Energy
MRI Software
Energy management and monitoring platform from MRI Software, built on the eSight Energy product MRI acquired in 2021. Covers metering, bill validation, tenant billing, anomaly alerts and carbon reporting.
Full profileThe main differences
Decision factors that actually separate them
- Getting data in. MRI Energy wins clearly. Named protocols mean an integration conversation you can scope. For EnergyCAP, no protocol, platform or named third party integration appears on the readable pages, so the integration list is empty rather than guessed.
- Getting cost out. EnergyCAP wins on the finance side with the general ledger export and chargeback workflow. MRI Energy wins on tenant recharge, which is a different problem with a different buyer.
- Standards and frameworks. MRI Energy names ISO 50001 and the Greenhouse Gas Protocol. EnergyCAP names greenhouse gas tracking without a scope structure or named framework, so it will not carry an assured disclosure alone.
- Water and gas. Documented for MRI Energy. Could not be verified as distinct features for EnergyCAP from published sources.
Unverified on both sides
Neither vendor publishes an API or mobile access statement that could be verified, which raises data portability questions for both, and is a slightly odd gap for MRI Energy given how integration friendly the rest of its material is. Tariff analysis, emissions scope structure and demand management could not be verified for either. Benchmarking is documented for EnergyCAP and unverified for MRI Energy.
One technical caveat worth carrying into the call
MRI names OPC Historical Data Access. OPC HDA is classic OPC rather than OPC UA, so confirm the exact variant your historian or plant systems speak before assuming compatibility.
Access and transparency
EnergyCAP main site returns HTTP 403 to automated access on the home page and four subpaths, and help and docs subdomains either do not resolve or fail TLS verification, so the capability detail here comes from two vendor authored campaign subdomain pages that agree with each other. The MRI product page loaded normally.

Read the full assessmentWhich to choose
Choose EnergyCAP when the organisation problem is invoice volume and financial control. Public sector estates, school districts, universities and multi account corporate portfolios with a real approval and chargeback process are its natural home, and ENERGY STAR benchmarking support helps where ordinances bite.
Choose MRI Energy when you need to read the building rather than only the bill, or when you are a landlord recharging tenants. The named protocol support is the strongest practical argument in its favour: it is the difference between a project you can plan and one you discover during implementation. If you already run MRI property software, the integration case strengthens further.
Both have brand discontinuity in their history, and both carry commercial opacity: neither publishes a figure, and MRI offers an Energy ROI Calculator which is a savings estimator rather than a price. Expect enterprise real estate software terms from MRI. Whichever you pick, get your meter data model right first, because both products will faithfully report nonsense if you feed them nonsense. See validating meter units in energy reports and threshold vs statistical anomaly detection, since both products advertise anomaly detection and the two approaches behave very differently in practice.
Frequently asked questions
No. Wattics was acquired by EnergyCAP in August 2022 and wattics.com now redirects permanently to energycap.com. eSight passed to BID Equity in April 2018 and then to MRI Software, completing 2 November 2021, and is marketed as MRI Energy. Evaluate the successors.
MRI Energy, by a wide margin, and it is the best documented in the whole category: oBIX, Modbus TCP over IP and OPC Historical Data Access are named explicitly, with IoT and BMS connectivity and PI Historian ingestion evidenced. Confirm whether OPC HDA or OPC UA is what you need.
MRI Energy. It combines utility bill validation with tenant utility billing, which suits commercial landlords recovering energy cost. EnergyCAP does campus chargebacks, which is internal cost allocation rather than tenant invoicing.
Neither does. EnergyCAP readable pages link to a pricing section with no amounts, and the main site blocks automated access so it cannot be confirmed whether a figure appears there. MRI offers a demo booking and an ROI calculator, which estimates savings rather than cost.
