4 circuits off 1 DIN-rail unit, each with its own meter?
The Shelly Pro 4PM runs 4 loads with per-channel power monitoring, each with its own switch input. Lighting zones, a pump and a heater on a single 4-module device, with every kWh counted. Diagram: Shelly.
Mixed switches and buttons on the 4 inputs?
Each Shelly Pro 4PM input can be a toggle or a momentary button independently, so an old board with a mix of switch types moves to 1 device without changing the wall plates. Diagram: Shelly.

About this product
The Shelly Pro 4PM is the top of the DIN-rail relay range: 4 channels, each power-metered, rated 16 A per channel and 40 A total. A built-in colour LCD shows channel state and consumption at the board itself, useful in a switchboard where you'd otherwise reach for the app.
It measures voltage, current and power per channel, and carries a physical Ethernet (RJ45) port alongside Wi-Fi and Bluetooth so it can run on a hardwired LAN where switchboard Wi-Fi is unreliable. Protection is comprehensive: overheating, overvoltage, overcurrent and overpower, with an internal temperature sensor, and it runs standalone through its local web interface with scripting, schedules and MQTT.
Being Pro-series it carries Shelly's 5-year warranty tier and is built for licensed-electrician installation in the board. It's the metered, 4-circuit answer where the Pro 1PM/2PM cover 1 or 2.
