The honest worry is range: will one hop reach from B2 up to the monitor room? You don't have to gamble on it. Siliqs nodes form a self-healing mesh by default — if a single hop is marginal, you drop in another node in between and it relays automatically. No setup, no re-configuration.
A building or facilities manager has an energy meter sitting in the basement — a normal RS485 / Modbus RTU power meter. They want its readings at a desk on the ground floor: how much power is being drawn, kWh, maybe voltage and current. Between the two points are two floors of reinforced concrete. Pulling a new signal cable up the riser is disruptive and expensive, and Wi-Fi neither reaches nor stays reliable through that much concrete.
Two small boxes, a self-healing mesh, and no cable between the floors.
A Siliqs node wires to the meter's existing RS485 terminals (A/B) and polls the Modbus registers you care about — kWh, power, voltage, current.
Each reading is sent over sub-GHz LoRa — no new cable, no internet. Because it's a mesh, the data will hop across as many nodes as it needs to reach the monitor room.
A second unit in the monitor room receives the data and hands it to a screen, a logging PC, or your MQTT / building system — using the free Siliqs Gateway app.
Then you add a node — and that's the whole answer.
This is why you don't have to gamble on coverage: the worst case isn't “it doesn't work” — it's “add one more inexpensive node,” and it works.
Usually in a single hop, yes — LoRa uses sub-GHz radio (around 920 MHz in Taiwan) at a low data rate, which penetrates reinforced concrete far better than Wi-Fi or Bluetooth at 2.4 GHz. And you're not relying on one hop: the nodes form a self-healing mesh, so if a link is marginal you add a node in between and it relays automatically.
You add a node in between — that's it. Siliqs nodes mesh by default, so a node placed in a stairwell or a floor between (it only needs power) relays the data automatically, with nothing to configure. The mesh also self-heals if a node drops.
No. The only wiring is the short, existing RS485 connection to the meter. The link between floors is fully wireless.
Any energy or power meter that has an RS485 / Modbus RTU interface.
No. The link is self-contained — a node at the meter and a receiver on the ground floor. No LoRaWAN network server or internet is required.
No. The node is flashed and configured from a web browser with free Siliqs tools — you set the meter's Modbus poll plan by point-and-click.
Yes. Additional meters can be added on the same wireless link, with multiple nodes reporting to one receiver.
