Single-Phase DIN-Rail Smart Meter (4G)
The D1P-4G drops into any consumer unit on a standard 35 mm DIN rail and reports straight to the Splinergy cloud over 4G LTE. Ideal where there is no reliable Wi-Fi: each unit is independently online, so a single tenant, room or circuit can be metered, billed and switched remotely.
