What It Does
Built for energy.
A pulse counter that transforms existing utility meters into wireless LoRaWAN devices — read gas, water or electricity meters remotely with no meter replacement. LoRaWAN decoder: Milesight EM300-DI payload decoder & codec (GitHub)
Highlights
Retrofit any meter
Clips to the pulse output of an existing gas, water or electricity meter via a standard 3.5 mm dry-contact cable — no meter replacement, no M&E contractor, no disruption to supply.
LoRaWAN, no cabling
Transmits pulse counts over LoRaWAN EU868 so meter data reaches the dashboard without running new signal cable through plant rooms or riser shafts.
Five-year battery
Up to five years on a single replaceable cell at a ten-minute interval — long enough to outlast most facilities management contracts without a site visit.

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.
