Hoval TopTronic E Measuring Module
Hoval module for up to 16 M-Bus meters with energy, power, flow, volume and temperatures over Modbus TCP.
The Hoval TopTronic E Measuring Module is a controller module that reads up to 16 meters over M-Bus in Hoval TopTronic E systems, for example in boiler plants and greenhouses. This Modbus TCP template reads energy, power, flow, volume and temperatures of every meter through the Hoval Modbus gateway into ModbusCloud.

If a device is not in the library yet, we build the template for free as soon as we have the register data.
Use cases
- Collect the meter readings of a boiler house or of greenhouse sections in one dashboard and compare energy per meter.
- Track energy and volume over 365 days and download them as CSV for an energy report or an invoice check.
- Get an alert when the power or the temperature difference of a meter crosses a threshold.
- Share a PDF report with the energy readings of each meter with the building owner.
Installation
Connect the Hoval Modbus gateway of the TopTronic E system to the same network as the ModbusCloud Gateway and give it a fixed IP address.
Check the address of the measuring module on its DIP switch or on the TopTronic E operating module. This template is for module address 1.
In ModbusCloud, add a Modbus device with Modbus TCP, the IP address of the Hoval gateway, port 502 and unit ID 1, then import this template.
Check that M-Bus Meter 1 Energy and M-Bus Meter 1 Serial Number match the display and type plate of the first meter.
Things to watch for
The Hoval gateway does not answer. What should I check?
Check that the ModbusCloud Gateway reaches the IP address of the Hoval Modbus gateway, and use port 502 and unit ID 1. The Hoval gateway has to be registered in the HovalConnect app. Meter positions without a meter can time out.
Which meter is M-Bus Meter 1?
M-Bus Meter 1 to 16 are the meter positions of the measuring module. Compare the Serial Number register of each position with the serial number on the type plate of the meter to see which meter sits where.
How do I read a second measuring module?
Every module has its own address on the TopTronic E bus. In the Hoval Modbus data point list the module with address n is MWA UnitId 384 plus n, with its own register addresses. This template is for UnitId 385. Make your own template in ModbusCloud with the addresses Hoval lists for your UnitId.
In which units do the meter values arrive?
Energy comes in MWh with three decimals, a resolution of 1 kWh. Power comes in kW and volume in m³, each with one decimal, and the flow rate in l/h. Compare one reading with the meter display before you use the values for billing.
