What Othermo does
Othermo GmbH is a German IoT company that builds a manufacturer-agnostic heating management system for operators of large residential heating portfolios, primarily property management companies, housing associations, and real estate portfolio holders. The company is headquartered in Alzenau, Germany, was founded in 2018, and operates with a team of 1-10 employees under managing directors Dr. Dennis Metz and Thomas M. Bach.
The core product stack comprises three components: the othermo Gateway, an IoT hardware device with an integrated cellular modem that connects to heating systems via standard interfaces (M-Bus, eBus, CAN-Bus, RS-485) without requiring local internet; the othermo Portal, a web-based monitoring, alarm management, and remote control platform that exposes a digital twin of each heating system with over 150 control parameters; and the Automatic Optimization Autopilot module, which continuously adjusts heating curves, supply and return temperatures, night setback schedules, and seasonal modes using thermodynamic rules and Deutscher Wetterdienst weather forecasts. The system supports gas central heating, district heating transfer stations, heat pumps, hybrid systems, CHP, and pellet heating, and the company cites 15-20% energy and CO2 savings, with 10-13% independently verified in a 200-system A/B study conducted with EBZ Business School.
Othermo sells through a consultative direct enterprise field-sales motion targeting German landlords such as Vonovia, Gewobag, LEG NRW, TAG Immobilien, Mark-E, GWH, Edistherm, Woge Werdohl, and Wohnbau. Revenue is generated from IoT hardware sales combined with a recurring software subscription for the portal and optimization services. Pricing is quote-based and not publicly disclosed. The company holds ISO/IEC 27001:2022 certification for IoT solution operations and processes all data on German servers in compliance with GDPR.

Revenue model
- IoT Hardware + Software Subscription: Othermo generates revenue through the sale of IoT gateway hardware combined with a recurring software subscription for their monitoring, optimization, and remote access portal. The hardware (gateway) enables connection to heating systems, while the software provides the digital twin functionality, automated optimization, and alarm services. The model appears to be a hybrid of hardware_sales and subscription_recurring revenue.

Othermo competitors and assessment
Company assessmentRegional players
- Thermondo: Berlin-based heating-installation and digital service company focused on heat-pump retrofits in Germany. Comparable DACH go-to-market and overlap on heat-pump optimization, but anchored on installation rather than monitoring software.
Direct peers
- GridX: German energy management software company providing optimization and analytics for heat pumps, PV, EV charging and home energy systems to utilities and OEMs. Closely comparable technology and business model targeting the same European energy-transition theme.
- Loxone: Austrian/German smart building automation provider covering HVAC, energy and access control with hardware gateways and a cloud platform. Competes for the same property-management and housing-association customer with broader building automation scope.
- Tado°: Munich-based smart heating control company selling manufacturer-agnostic thermostats and optimization software to households, housing associations and utilities. Direct competitor in the same smart heating/energy optimization category targeting German-speaking customers.
- Kiwigrid: German IoT energy management platform connecting distributed energy assets (heat, PV, EV, storage) for utilities and property operators. Comparable in delivering a manufacturer-agnostic optimization layer on top of building energy assets, with similar target customers.
Broad incumbents
- Netatmo (Legrand): Smart climate and home device company (owned by Legrand) offering smart thermostats, valves and energy monitoring. Broad incumbent in connected home climate, with partial overlap with Othermo's residential heating optimization.
- Bosch Thermotechnology: Large incumbent HVAC manufacturer offering EasyControl and connected heating solutions with cloud monitoring and remote access. Overlaps with Othermo at the customer level but bundles software with proprietary hardware.
- Viessmann: Global HVAC manufacturer with its own ViCare and ViGuide IoT platforms for connected heating systems. Represents the OEM-bundled alternative that Othermo's manufacturer-agnostic positioning explicitly competes against.
Emerging players
- Senercon: German specialist focused on heating-system monitoring and optimization for housing and commercial portfolios. Comparable niche overlap with Othermo's heating-specific digital twin and remote monitoring offering.
- Eliona: European building/energy IoT platform providing monitoring and optimization across HVAC, energy and asset data for property operators. Competes for the same digital-twin-and-portal positioning at building-portfolio scale.
