How to add a device in myPower24

Adding a device tells your LoggerV to start talking to a piece of hardware, so its data appears on the platform and it can take part in plant control. You do this once, during commissioning, with the Add Device wizard.

Before you start

The device is wired and powered, the logger is online, and you know how it connects: serial (RS-485 / RS-232), Ethernet (Modbus TCP) or CAN. For a Modbus device you also need its slave address and baud rate. Both are set on the device itself and myPower24 only reads them, so note them before you leave the device.

Step 1: open the wizard and pick the model

Go to My Devices > Overview and click add device (the + button).

The device list with the add device (+) button

Pick the manufacturer on Manufacturer Selection, then the model on Device Selection, using the Type to search devices box to filter. Each model card has a ? icon that opens its help article, so you can confirm you have the right one.

Manufacturer Selection

Device Selection

On old logger firmware the wizard refuses to load and tells you to update the logger or add devices via the Interface tab. See the last section for that route.

Step 2: choose the interface

On Interface Selection, choose the LoggerV port the device is wired to. Each port shows its settings, a Guide button for the physical connection, and the status Attached once it is in use. If the port you need is missing the wizard names the type, for example "No CANBUS interface detected".

Interface Selection

A device that announces itself, such as a Solar MD CAN battery, is finished here. There is no scan and no address to enter.

Step 3: Modbus devices, scan for it

On the Scan step, fill in what the device needs:

  • Modbus Slave ID: - the address set on the device, 1 to 255.
  • Serial Number: - some models only. Use the real serial number, or a unique string if it has none.
  • IP Address: and TCP Port: - Modbus TCP only. The port defaults to 502, which must be enabled on the device.

Then click Try to connect. On success you see "Device succesfully scanned" and the wizard closes.

If you are unsure of the address, click Try scan range instead, enter a range like 1-10 or comma-separated numbers, and click Scan. Each address reports Discovered with its serial number, or Not Detected; click Select on the row you want. This button appears on serial ports only, and only on recent logger firmware.

The Modbus Scan step

If a Modbus device will not connect, it is almost always the address, the baud rate, or (on RS-485) swapped A/B wiring. Confirm the address and baud set on the device, and that the port's speed matches, before rescanning.

Setting the interface speed

A port's speed belongs to the interface, not the device. The gear on a serial port opens Baud Rate, Data Bits, Stop Bits and Parity; click Change to apply. A CAN port shows its Bus Speed read-only.

Several Modbus devices can share one RS-485 port, each with its own address, but they must all run at the same baud rate. Changing it affects every device on that port.

Confirm it worked

The device appears under the port's Enabled devices list on the LoggerV's Interfaces tab, and under My Devices in its type group, such as HYBRID INVERTERS, STORAGE or ENERGY METERS. Open it and check the live values are updating.

Adding a device from the Interfaces tab

Without the wizard: on the Interfaces tab open the port's pane, click Add Device, pick the model in the Select Device to Add dialog and click Add.

Who can do what

Adding a device needs more than view-only access on the plant: the Installer or Full control level. Below that the scan never reaches the logger and the app answers "Not authorized: view-only access to this plant".

Two extras have their own permissions: uploading a connection guide needs connection_guide, and replacing a device or manufacturer image needs Image_Upload. Without them the wizard does not offer those buttons.
