Modbus metering made simple
Meters, controllers, inverters: anything with a register map.
One RS-485 pair leaves the gateway, lands on the first device and goes on to the next. Metbox polls each address in turn, reads it by name rather than by register number, and writes back where a device takes settings.

Registers, already mapped
Each supported model has a driver of its own, so a device arrives reporting energy, flow and temperature by name instead of as register 40021.
Device register
Addresses, serial numbers, baud rates and where each box sits, in one place, so a cabinet somebody else wired stays documented.
Analytics online
Consumption and live values by hour, day or month, for one device or a whole site, with periods you can compare in the browser.
Alerts
A device that stops answering, a value outside its band, a line that goes quiet: flagged as it happens and sent to whoever needs to know.
Reports and billing
Consumption reports and billing exports on a schedule, as files or through the API into the system you invoice from.
What goes at the head of the chain.
One box speaks Modbus to the cabinet. The second is for the meters that will never be on a rail.
Wired gateway
Metbox Pro
Modbus RTU over RS-485 and Modbus TCP over the network, with wired M-Bus on the same box. It polls each address, writes back where it is allowed to, and reaches the platform over 4G.

Metbox wM-Bus 230V
For the water and heat meters that were never wired to anything: it hears them over radio, whatever the brand, and reports into the same platform as the cabinet.

Why Modbus?
Not only meters
Meters, heating controllers, inverters, pumps: if it has registers, it can be read.
Already in the cabinet
RS-485 is on nearly every meter and controller sold for a switchboard.
No more trips to the board
The readings come to you instead of somebody with a laptop and a torch.
Nothing to plan
No coverage to check, no dead basement, no radio to answer for.
Values you can check
Every register we read is documented per model, not guessed at.
No lock-in
The spec is public and free. Nothing about the line is ours to own.

The devices we already speak to.
Every model here has been tested in our office and has a register map of its own, so it arrives reporting named values rather than numbers to work out.
