Dezem

What Dezem does

deZem GmbH is a Berlin-based IoT company founded in 2003 that develops and distributes hardware, software, and services for energy and environmental management. Its commercial offering is built around three integrated pillars: a DataSuite modular analytics software suite (deZemVis, deZemBoard, deZemSheet, deZemReport, deZemAd, deZemCap, plus the deZemTemplating feature for automated multi-site dashboard rollouts), proprietary data acquisition hardware led by the battery-free Harvy2 LoRaWAN current sensor (also offered in Rogowski and external-antenna variants) and edge computers (iPCX data logger, iPCR-M edge controller), and a central data management platform (deZem Plattform and deZem.io) that aggregates heterogeneous IoT data via standard protocols in a manufacturer-neutral architecture. The platform is ISO 9001, ISO 27001 (since July 2024), and ISO 50001 compliant, with data hosted in German data centers and BAFA funding eligibility for energy management software.

The company monetizes through a hybrid model combining hardware sales (Harvy2 sensors, edge devices, and a Messkoffer mobile measurement case sold via an online shop), recurring SaaS subscriptions to DataSuite modules on annual billing, and professional services covering project support, installation, integration of existing systems, consulting, and ISO 50001 pre-audits typically contracted over multi-year terms. GTM is primarily direct enterprise field sales supplemented by an installation partner network and resellers such as iot-shop and m2m Germany, with lead generation through industry events (SCCON, E-World, ZIA Sustainability Congress, Future Industry Minds, Smart Country Convention), content marketing, and partner webinars. Customers include Douglas Group (ESG-compliant energy monitoring across ~1,900 stores in 22 countries with ~5,200 sensors), Siemens Real Estate, NTT data centers, Stromnetz Berlin, HTW Berlin, and hospitals, serving verticals such as large retail chains, data center operators, smart cities and municipalities, real estate and asset managers, and industrial companies. Operations span Europe, the Americas, and Asia through a network active in over 30 countries, with a team of approximately 33 colleagues based at the Berlin-Charlottenburg headquarters.

Core offering

deZem develops and sells an integrated IoT system for energy and environmental management, combining proprietary battery-free LoRaWAN current sensors (Harvy2) and edge computing hardware with the modular deZem DataSuite analytics software and a manufacturer-neutral deZem Platform for data aggregation, monitoring, ESG/ISO 50001 reporting, and sub-metering. The company also delivers professional services for installation, integration, pre-audits, and consulting.

Product overview

Dezem offers a modular IoT system for capturing and analyzing IoT data, consisting of three integrated pillars: DataSuite (modular IoT analytics software), Data Acquisition (hardware sensors and edge computers), and Data Management (deZem Plattform and deZem.io cloud platforms). The DataSuite comprises six software modules (deZemVis for visualization, deZemBoard for dashboards, deZemSheet for real-time spreadsheets, deZemReport for automated reporting, deZemAd for administration, and deZemCap for manual meter reading via smartphone app), plus the deZemTemplating feature for automated dashboard rollouts. Hardware products include Harvy2 and Harvy2 Rogowski battery-free LoRaWAN current sensors, LoRaWAN Starterkit, iPCR-M Edge Controller, iPCX Data Logger, and Mobile Measurement Cases. The platforms integrate all data sources for comprehensive energy management and monitoring.

Products and services

• deZem DataSuite Modular analytics software platform for energy and environmental data with modules for visualization (deZemVis), dashboards (deZemBoard), spreadsheets (deZemSheet), reporting (deZemReport), advertising displays (deZemAd), data capture (deZemCap), and templating (deZemTemplating). Used by enterprises to monitor consumption, generate reports, and meet ISO 50001/ESG requirements.
• deZem Platform (deZem.io) Manufacturer-neutral, real-time IoT data aggregation platform that ingests sensor and meter data via open standards (OPC UA, BACnet, Modbus, MQTT) and standard IoT protocols. Used by enterprises to consolidate multi-vendor metering data for analytics and reporting.
• Harvy2 Current Sensor Battery-free LoRaWAN current sensor available in CT, Clamp, and Rogowski variants for retrofit sub-metering. Installed non-invasively on existing cabling in live operation, sending current measurements wirelessly to the deZem Platform. Long product life thanks to battery-free design.
• iPCR-M Edge Controller Edge computing device for local acquisition, processing, and forwarding of energy and environmental data from connected meters and sensors to the deZem Platform.
• iPCX Data Logger Data logger hardware for capturing measurements from upstream meters and sensors and transmitting them to the deZem Platform.
• Messkoffer (Mobile Measurement Case) Portable measurement kit for ad-hoc energy and environmental audits at customer sites; used to record consumption and conditions during short-term measurement campaigns.
• LoRaWAN Starterkit Starter kit for prospective customers to pilot LoRaWAN-based energy monitoring with deZem-compatible sensors and gateways before full deployment.

Broad incumbents

• Schneider Electric: Schneider Electric's EcoStruxure platform spans building energy management, submetering and ESG reporting at global enterprise scale. It is a broad incumbent competitor to deZem in the same energy management software category, with much larger R&D and sales resources.
• Siemens Smart Infrastructure: Siemens offers Desigo CC and Navigator for building and energy management across global commercial real estate. As a broad incumbent it overlaps with deZem's DataSuite proposition, and notably Siemens Real Estate is itself a deZem customer.
• Honeywell Forge: Honeywell Forge is a building performance and energy management suite targeting enterprise real estate and industrial sites. It competes with deZem for large multi-site energy monitoring and ESG analytics mandates.
• ABB Ability: ABB Ability offers energy and asset management software alongside industrial automation hardware. It is a broad incumbent with overlapping capabilities to deZem, especially in industrial energy monitoring and data platform layers.

Emerging players

• Wirepas: Wirepas provides mesh wireless connectivity for large-scale IoT including energy and submetering use cases. It is an emerging player in the same LoRaWAN/IoT connectivity ecosystem that underpins deZem's Harvy2 deployments, with potential partnership or competitive overlap.
• Wattsense: Wattsense is a French IoT building connector that aggregates building systems data for energy monitoring and facility management. It is comparable to deZem in serving multi-site building operators needing unified energy and operational data, though with a connectivity-first rather than metering-first approach.
