Automated safety in industrial facilities is no longer a matter of convenience, but a mission-critical requirement. A single undetected water leak can cause severe mechanical and electrical damage – especially in locations without constant supervision.
In the following case study, we present an effective and standalone alerting solution, implemented with the SMSEagle SMS Gateway and the technological consulting support of SmartNode Ltd., in collaboration with Airlock Ltd.

SmartNode Kft. is a Hungarian company specializing in industrial monitoring and IoT solutions. Their expertise lies in creating innovative sensor-based systems that help protect infrastructure and ensure operational continuity for customers across different industries.
The project took place at a healthcare facility in Hungary, where there is no continuous, 24/7 operational staff presence. A previous pipe burst resulted in the complete flooding of the central heating plant room, causing severe damage to pumps, sensors, valve actuators, and partially to the electrical distribution panel. To prevent similar incidents in the future, it became urgent to implement an alerting system capable of operating independently from the existing BMS and sending notifications via SMS and voice calls in an autonomous manner.

Based on the recommendation of SmartNode Ltd.’s experts, the SMSEagle SMS Gateway device was selected for the project. The device comes with factory-available extensions such as a water leak sensor and voice call functionality. One key requirement was support for the Hungarian language: the unit includes three pre-recorded voice samples (two female and one male voice).
A specific challenge of the installation environment was the weak signal reception, as the distribution panels were located in a basement. This was resolved using an outdoor 4G antenna with a 10-meter cable. Continuous operation of the device was ensured by an uninterruptible power supply (UPS).
One of the SMSEagle’s four digital inputs was connected to the water leak sensor, while another was assigned to the power outage sensor. The device operates based on event triggers: upon detecting a change in input, it sends a pre-configured SMS and sequentially calls the designated phone numbers.
Whether it’s a water leak or a power outage, the system immediately sends an SMS and automatically initiates voice call notifications. If the recipient does not answer, the system proceeds to the next number. Once a call is answered, the device plays a pre-recorded voice message and then hangs up. The cycle repeats for unanswered numbers. In the event of a power outage, the device continues operating on UPS power and is capable of sending an early warning that the system may soon become unreachable.
“Although the SMSEagle can be integrated into a Tridium Niagara system, in this case it was deployed as a standalone emergency solution. Its setup is quick and user-friendly, and its operation is highly reliable. It provides fully autonomous monitoring in emergency situations.”

This project clearly demonstrates how the protection of an industrial facility against unexpected water leaks can be achieved efficiently—even on a limited budget. With the professional support of SmartNode Ltd., the selected SMSEagle solution offers fast deployment, flexible configuration, and outstanding reliability. It is an ideal choice even in environments without permanent staff or where the existing building management system does not provide sufficient safety in emergency situations.
