What It Does
Built for energy.
A single-phase LoRaWAN energy meter on DIN rail, MID-certified to Class 1.0 accuracy — billing-grade electricity metering for a building or a tenant supply.
Highlights
MID-certified billing accuracy
Class 1 accuracy to EN 50470-3 and MID approval means sub-meter readings are legally defensible for tenant billing and landlord cost-recovery in schools, social housing and NHS estates.
Twelve parameters, one meter
Active energy, reactive energy, power factor, THD, voltage, current, frequency and max demand are all logged and transmitted, giving energy managers the full picture without secondary equipment.
DIN rail, two modules wide
At 100 × 36 mm the SDM230 fits into any standard distribution board on two DIN modules, so it can be retrofitted alongside existing breakers without requiring a new enclosure.

Complete The Setup
You will also need a gateway.
Every LoRaWAN sensor needs a gateway to reach the internet. One gateway covers a whole building — the Milesight UG65 is the standard choice for most sites.
On The Platform
A device on its own, or part of the bigger picture.
Buy this device and run it yourself, or have it monitored on the Planetic platform — live dashboards, standards tracking and automatic alerts, with the compliance evidence kept for you.
Questions
Good to know.
- Do I need anything else to use this device?
- Every LoRaWAN sensor needs a gateway to reach the internet. One gateway covers a whole building — the Milesight UG65 is the standard choice for most sites. The gateway itself does not need a sensor to run.
- Is the price ex VAT?
- Yes — all prices shown are ex VAT. VAT is added at checkout where applicable.
- Can I have it monitored on the Planetic platform?
- Yes. Buy the device outright and run it yourself, or have it monitored on Planetic — live dashboards, standards tracking and automatic alerts, with compliance evidence kept for you.
