What Are The Drivers Of The OpenTherm Internet Of Things (IoT) Gateway Market?

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 centralised applications. The increasing adoption of smart home automation systems is due to the growing demand for energy efficiency, as these systems optimise 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 helps smart home automation systems by enabling seamless communication between boilers and smart thermostats, allowing precise temperature control, improved energy efficiency, and centralised remote management 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 used smart home security solutions such as internet-connected alarm systems, smoke detectors, security cameras, and smart doorbells, compared with just 17% in 2022. Therefore, the rising adoption of smart home technologies and connected devices is driving the growth of the opentherm internet of things (IoT) gateway industry. 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 refer to physical objects embedded with sensors, software, and connectivity that enable them to collect, exchange, and act on data over the internet without requiring constant human intervention. The increasing adoption of Internet of things (IoT) devices is due to the growing demand for automation, real-time data connectivity, and improved efficiency across homes, industries, and services. Opentherm internet of things gateway enables Internet of Things devices by facilitating seamless, bidirectional communication between smart heating systems and connected home platforms, allowing real-time monitoring, 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 around 40 billion and is projected to grow to 49 billion by 2026, representing an annual growth rate of 7%. Therefore, the increasing adoption of internet of things devices is driving the growth of the opentherm internet of things (IoT) gateway industry. 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 amount of money paid by a residential consumer for the electrical energy they use within their home over a specific period, including charges for consumption, tariffs, taxes, and other utility fees. Rising household electricity costs are primarily due to increasing energy demand from a growing population, higher use of electrical appliances, and expanded adoption of energy-intensive technologies in homes. Open therm internet of things gateway enables precise modulation-based boiler control and real-time energy optimization, which reduces unnecessary heating cycles and helps lower household electricity costs through improved energy efficiency and smarter consumption management. For instance, in October 2024, according to Eurostat, a Luxembourg-based European Union, in 2023, average household electricity prices in the EU rose to $31.21 per 100 kWh in the first half of the year, up from $27.32 per 100 kWh during the same period in 2022. Therefore, the rising household electricity costs are driving the growth of the opentherm internet of things (IoT) gateway industry.
