With a new trade fair presence, innovative solutions and an important strategic step for the future development of the industry, Sontex presented itself at HEIKOM 2025 in Erfurt as a strong driving force for digital transformation in submetering.
Commitment to a Strong Industry
Another highlight surrounding HEIKOM 2025 was the announcement of Sontex’s expanded cooperation with DEUMESS e.V.: Sontex will become a premium sponsor of the association going forward. With this step, the company is reaffirming its commitment to innovation, knowledge transfer and networking within the submetering industry.
For many years, DEUMESS has supported metering service providers, municipal utilities and real estate companies through training, advocacy and networking. With events such as HEIKOM, the association provides important platforms for professional exchange and for jointly shaping the market requirements of the future.
The future premium partnership is based on a shared understanding: modern metering solutions and digital services create transparency around energy and water consumption and therefore make an important contribution to sustainable practices in buildings.
At HEIKOM 2025, Sontex showcased innovative metering solutions, the Sonexa platform and a joint presence with E. Wehrle. With the new premium partnership with DEUMESS e.V., Sontex is also strengthening its commitment to the digital future of submetering.
