Modbus RS485 Add-on allows The Pill by Shelly to communicate with compatible heat pumps, ventilation systems, thermostats, and building controllers. Connected through the 5-Terminal Add-on, it enables data exchange over RS485 (Modbus RTU) and provides access to operational data for monitoring, alerts, and automation workflows. This helps centralize visibility across offices, retail spaces, server rooms, and multi-zone commercial buildings.
