Wattsense Bridge and Tower Control

Wattsense is a French SAS founded in 2017 by Louis Vermorel, with its headquarters near Lyon, France. Siemens Smart Infrastructure acquired the company in 2021 to boost IoT systems for small and medium buildings, while the Wattsense brand continues. It states more than 250 clients, including Siemens, CBRE, Dalkia and Veolia.

The Wattsense Bridge is a plug-and-play multi-protocol IoT connector that collects data from HVAC, meters and sensors regardless of brand. Wattsense Tower Control is a BMS for small and medium buildings with dashboards, scenarios and alarms, and Tower Lift sends data to third-party cloud services. A configuration console with an equipment library handles setup remotely.

• Wattsense Bridge: IoT connector for local data use across brands.
• Tower Control: BMS with dashboards, graphs, scenarios, alarms and archives.
• Tower Lift: cloud connector for third-party digital services.
• Protocol support: LoRaWAN, Modbus IP and serial, BACnet, M-Bus, LPB and KNX.
• Equipment library: remote configuration with a setup wizard.
• Open API: integration with analytics partners such as EGREEN.

A building services integrator in Vietnam can connect chillers and meters of mixed brands into one dashboard. A retail chain can centralize HVAC and energy data across stores. A hotel can send meter data to an ESG reporting platform.

Plug-and-play setup avoids complex IT projects. One device collects data from many brands and protocols, protecting existing equipment investment. Open API and partner integrations such as EGREEN send data to energy analytics services. Remote configuration reduces site visits.

Regulation such as EU building automation requirements pushes owners of small and medium buildings to connect equipment and meters to energy services. In Vietnam and Southeast Asia, retrofit gateways that unify legacy HVAC and meters help offices, hotels and retail chains build energy dashboards without replacing equipment.
