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 a gateway?
- Every LoRaWAN sensor talks to a gateway, which carries the data to the internet. One gateway typically covers a whole building. If you do not have one yet, add a Milesight UG65 — the standard choice for most sites.
- Do the sensors need WiFi or a SIM card?
- No. Sensors connect over LoRaWAN to the gateway. Only the gateway needs an internet connection — by Ethernet or a cellular SIM — so the sensors never touch your IT network.
- How are the devices delivered?
- Devices are shipped to you in the UK, ready to mount. Most are wireless and battery-powered, so installation is quick and needs no wiring or an electrician.
- Can Planetic monitor the devices for me?
- Yes. Buy a device outright and run it yourself, or have it monitored on the Planetic platform — live dashboards, standards tracking, alerts and the compliance evidence kept for you.
- Are the prices ex VAT?
- Yes. Every price shown is the recommended retail price, excluding VAT.
