An OpenTherm internet of things (IoT) gateway is a communication interface that links OpenTherm-compatible heating equipment with the internet or local communication networks, allowing remote monitoring and management. It converts and exchanges data between OpenTherm protocol devices and internet of things platforms, supporting smart automation, improved energy efficiency, and seamless integration with residential or commercial building management systems.
The primary product types of openTherm Internet of Things (IoT) gateway include wired gateways and wireless gateways. Wired gateways are communication devices designed to connect heating systems with smart devices through physical network connections, enabling monitoring and control capabilities. These products are available with connectivity options including Ethernet, Zigbee, Bluetooth, cellular, and hybrid multi-protocol gateways, and are distributed through online and offline sales channels. Their applications span residential, commercial, and industrial environments, and they are used by end users including heating, ventilation and air conditioning manufacturers, smart home solution providers, system integrators, building automation companies, energy management firms, and utilities or energy service providers.
Tariffs are influencing the OpenTherm internet of things (IoT) gateway market by increasing the cost of imported communication modules, microcontrollers, and gateway hardware components used in smart heating control systems. This is affecting deployment schedules for residential and commercial HVAC modernization initiatives, particularly across import-dependent regions including Asia-Pacific and Latin America. Hardware-intensive categories such as wireless gateways and protocol conversion devices are experiencing the greatest impact because of their dependence on global semiconductor and electronics supply chains. At the same time, tariffs are encouraging domestic production of HVAC control devices, accelerating the development of regional supplier ecosystems, and motivating manufacturers to design more cost-efficient and modular gateway architectures to strengthen long-term market resilience.

This opentherm internet of things (iot) gateway market research report delivers a complete perspective of everything you need, with an in-depth analysis of the current and future scenario of the industry.
The opentherm internet of things (IoT) gateway market size has grown rapidly in recent years. It will grow from $1.12 billion in 2025 to $1.28 billion in 2026 at a compound annual growth rate (CAGR) of 14.8%. The growth in the historic period can be attributed to limited interoperability between heating systems and control platforms, early adoption of smart thermostats in residential heating, fragmented hvac communication protocols across manufacturers, growing need for remote heating control in urban households, increasing energy cost pressures driving efficiency improvements.
The opentherm internet of things (IoT) gateway market size is expected to see rapid growth in the next few years. It will grow to $2.2 billion in 2030 at a compound annual growth rate (CAGR) of 14.4%. The growth in the forecast period can be attributed to expansion of smart building automation and connected heating systems, rising demand for energy efficient and optimized heating management solutions, growth of retrofit adoption in legacy boiler infrastructure, increasing integration of heating systems with centralized building management platforms, advancement in remote monitoring and predictive heating control technologies. Major trends in the forecast period include increased adoption of opentherm enabled boiler modernization systems, growth of vendor agnostic heating control interfaces for residential and commercial buildings, expansion of retrofit smart thermostat gateway installations in legacy hvac systems, integration of heating systems with building management systems through protocol conversion gateways, rising deployment of demand response enabled heating automation and optimization gateways.
The increasing adoption of smart home automation systems is expected to propel the growth of the OpenTherm Internet of Things (IoT) gateway market going forward. A smart home automation system is a connected digital ecosystem that enables users to remotely monitor and control household functions such as heating, lighting, security, and appliances through internet-enabled devices and centralized applications. The increasing adoption of smart home automation systems is driven by the growing demand for energy efficiency, as these systems optimize electricity, heating, cooling, and appliance usage through automated control and real-time monitoring to reduce overall energy consumption and costs. The OpenTherm Internet of Things gateway supports smart home automation systems by enabling seamless communication between boilers and smart thermostats, allowing accurate temperature regulation, enhanced energy efficiency, and centralized remote control of heating systems. For instance, in October 2024, according to the Central Statistics Office, an Ireland-based government agency, in 2024, 30% of internet users utilized smart home security solutions such as internet-connected alarm systems, smoke detectors, security cameras, and smart doorbells, compared with 17% in 2022. Therefore, the growing adoption of smart home technologies and connected devices is contributing to the expansion of the OpenTherm Internet of Things (IoT) gateway market.
The increasing adoption of Internet of Things devices is expected to propel the growth of the OpenTherm Internet of Things (IoT) gateway market going forward. Internet of Things (IoT) devices are physical objects integrated with sensors, software, and connectivity features that allow them to collect, exchange, and process data over the internet without requiring continuous human involvement. The increasing adoption of Internet of Things (IoT) devices is driven by the growing need for automation, real-time data exchange, and enhanced operational efficiency across residential, industrial, and service sectors. The OpenTherm Internet of Things gateway supports Internet of Things devices by enabling seamless two-way communication between smart heating systems and connected home platforms, facilitating real-time monitoring, remote control, and energy-efficient automation across integrated IoT ecosystems. For instance, in July 2025, the European Commission, a Belgium-based governing body, reported that in 2023, the number of installed IoT-connected devices was approximately 40 billion and is expected to increase to 49 billion by 2026, representing an annual growth rate of 7%. Therefore, the increasing adoption of Internet of Things devices is contributing to the growth of the OpenTherm Internet of Things (IoT) gateway market.
The rising household electricity costs are expected to propel the growth of the OpenTherm Internet of Things (IoT) gateway market going forward. Household electricity costs refer to the total expenditure paid by residential consumers for the electrical energy consumed within their homes over a specific period, including usage charges, tariffs, taxes, and additional utility fees. Rising household electricity costs are mainly attributed to increasing energy consumption due to population growth, higher usage of electrical appliances, and the expanding adoption of energy-intensive technologies in households. The OpenTherm Internet of Things gateway enables precise modulation-based boiler control and real-time energy optimization, helping reduce unnecessary heating cycles and lower household electricity expenses through improved energy efficiency and intelligent consumption management. For instance, in October 2024, according to Eurostat, a Luxembourg-based European Union agency, in 2023, average household electricity prices in the EU increased to $31.21 per 100 kWh in the first half of the year, compared with $27.32 per 100 kWh during the same period in 2022. Therefore, the increasing household electricity costs are contributing to the growth of the OpenTherm Internet of Things (IoT) gateway market.
