Central heating control made simple
Keep the controller you have. Run it from anywhere.
Metbox connects to the controller already in your substation, reads what it is doing and puts it in the platform. Curves, setpoints and schedules are then yours to change from a browser.

Metbox platform

Your controller, understood
Danfoss ECL, OUMAN and the rest each have a driver of their own here, so a substation arrives with named values rather than register addresses.
Curves and setpoints in the browser
Change the heating curve, the room setpoint or the schedule from the platform, inside the limits the controller itself allows.
The substation, hour by hour
Supply and return temperatures, flow, power and pressure over any period, next to the outdoor temperature that explains them.
Alerts
A return that runs too warm, overheating, a curve that stopped answering the weather, a controller gone quiet: flagged as it happens and sent to whoever is on call.
AI control
The platform holds the forecast next to every reading it already has and trims the curve on both, so the building spends less heat for the same comfort.
What goes in the substation.
One gateway for the controller, and one for the meters around it when they report over radio.
Wired gateway
Metbox Pro
Talks to the controller over Modbus, RS-485 or RS-232, reads the wired meters on the same bus, and reaches the platform on its own mobile connection.

Metbox wM-Bus 230V
For the heat and water meters in the building: it hears every wireless meter around it, whatever the brand, and reports them alongside the substation.
The controllers we already speak to.
Every model here has been tested in our office and has a driver of its own, so it reports and takes changes back without any setup on site.

Nothing to replace
The controller stays where it is. Metbox reads it and writes back to it.
No drive to the substation
A change that used to be a site visit is now a field in the browser.
Curves that follow the weather
Heat the building for the day it is having, not for the coldest one.
Heat you stop paying for
Overheating shows up as a number, and so does what fixing it saved.
Every change on record
Who changed what, when, and what the building did afterwards.
