Hager ECR140D
Single-phase 40 A MID kWh meter with eight tariffs, read and switched over RS485.
The Hager ECR140D is a single-phase MID energy meter in one DIN module that measures consumption and feed-in on circuits up to 40 A. This Modbus RTU template reads voltage, current, power, power factor and imported and exported energy per tariff, and lets you select the active tariff from 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
- Show consumption and feed-in of a tenant, charging point or heat pump on a ModbusCloud dashboard.
- Keep 365 days of history of imported and exported energy for a monthly billing overview.
- Get an email when the current exceeds a limit you set, before the 40 A rating is reached.
- Switch the active tariff from an automation on a time schedule or energy price, and read energy per tariff.
- Compare imported and exported energy per day to see how much PV production is used on site.
Installation
Wire the meter into the single-phase circuit and connect its RS485 terminals to RS485 A and B on the ModbusCloud Gateway.
Terminate the bus with 120 ohm at both ends and use the same wiring polarity on every meter.
Use the push button to set the Modbus address, baud rate and parity, for example address 1, 19200 baud, even parity and 1 stop bit.
In ModbusCloud, add a Modbus device (RTU) with the same address and serial settings and import this template.
Check that voltage and imported active energy match the values on the meter display.
Things to watch for
The meter does not answer. What should I check?
Compare address, baud rate, parity and stop bits on the meter with the Modbus device in ModbusCloud; the meter has no fixed factory setting you can rely on. Swap A and B if nothing comes back, and check that both bus ends have a 120 ohm termination.
Why do the energy counters show whole kWh while the display shows decimals?
The main energy registers count in whole kWh. For a finer value, use Imported Active Energy Wh and Exported Active Energy Wh. These two need meter firmware 1.2 or later; older firmware gives no answer on them, and you can remove them from the device.
Can several ECR140D meters share one RS485 line?
Yes. Give each meter its own address from 1 to 247, set the same baud rate and parity on all of them, wire the bus as one line from meter to meter and terminate both ends.
What happens when I write a tariff or a Modbus setting?
Writing 1 to 8 to Set Tariff makes the meter count in that tariff right away; the register always reads 0. A new address or baud rate also applies at once, so the meter stops answering until you change the device in ModbusCloud to match.
