In the rental sector—whether it’s residential apartments, hotel rooms, or commercial spaces—transparency and control over resource consumption have become essential. The ADDERRA sub-metering solution offers a simple, modern, and cost-effective system that accurately tracks individual water and electricity usage.
ADDERRA is an ultrasonic sub-metering system with prepaid functionality and remote management. Each tenant pays only for what they actually consume, while the property owner receives timely and accurate payments—no manual calculations, no disputes, no surprises. Through a mobile app, users can top up their balance, monitor their consumption, and receive notifications when a usage limit is reached. In case of non-payment, the system can automatically restrict resource supply—fully remotely, with no need for staff intervention.
ADDERRA meters detect even the smallest flows, ensuring ultra-precise measurements and instantly responding to leaks, tampering attempts, or technical issues. They are resistant to polluted water, wear-free, and operate reliably in any environment—from small apartments to large hotel complexes.
The ADDERRA solution is already in use in hotels, apart-hotels, and multi-apartment buildings, where accurate and transparent consumption tracking is crucial among multiple users. This is especially relevant in countries with a dynamic rental market and strong demand for flexible, fair utility management.
ADDERRA makes sub-metering not only convenient but also profitable—for property owners, tenants, and the entire utility ecosystem.
ADDERRA – Fair consumption starts at just one liter.
