How to add a device in myPower24
Adding a device tells your LoggerV to start talking to a piece of hardware - an inverter, battery, energy meter, charger or sensor - 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. This guide walks through that wizard and the alternative per-port method on the Interfaces tab.
Before you start
- The device is physically wired to the LoggerV and powered on.
- You know how the device is connected - over a serial port (RS-485 / RS-232), Ethernet (Modbus TCP), or CAN.
- For a Modbus device, you know its slave address and baud rate (both are set on the device itself, not in myPower24).
- The LoggerV is online in the app. The wizard needs a reasonably recent logger firmware; on an outdated logger it shows "This feature is not supported by the current logger version. Please update the logger, or alternatively, add devices via the Interface tab" - in that case use the Interfaces-tab method near the end of this guide.
Open the Add Device wizard
From the device list, click add device (the + button); on a plant view the same wizard opens from Device Setup. The wizard opens on Select Manufacturer.
Step 1 - Choose the manufacturer
On the Manufacturer Selection screen, pick the device's manufacturer from the grid. Use the Type to search devices box to filter if the list is long. The header updates to Selected Manufacturer: .
Step 2 - Choose the device model
On Device Selection, pick the model. Each model card has a ? (help) icon that opens the model's help article in the knowledge base, so you can confirm you've got the right one. The header updates to Selected Device: .
What happens next depends on how the device is detected:
- Modbus devices (most inverters and meters) → you'll scan for the device (Step 3a).
- Auto-detected devices (CAN devices such as Solar MD batteries) → you'll just pick the interface (Step 3b); there is no scan.
Step 3a - Modbus devices: scan for it
First, on Interface Selection, choose the LoggerV port the device is wired to (for example RS485 (rs485-1)). Each port shows its current settings (baud rate, data/stop bits, parity for serial ports; IP details for Ethernet) and a status such as Attached. Then, on the Scan step, fill in what the device needs:
- Modbus Slave ID - the device's address (1-255). This must match the address set on the device.
- Serial Number - only asked for some devices; "Always use device actual serial number. If not available choose unique string representing the device."
- IP Address and TCP Port - only for Modbus TCP (Ethernet) devices; the default port is 502, and "Make sure Modbus TCP is enabled on port 502" on the device.
Then either:
- Try to connect - connect to the single address you entered. On success you'll see Device succesfully scanned and the wizard closes.
- Try scan range - if you're not sure of the address, this opens a Scan Range step. Enter a range as "- [1-254], or coma separated numbers like 1, 5, 6" (e.g.
1-10), then click Scan. Each address reports Discovered (with its serial number) or Not Detected; click Select on the row you want. (Range scanning needs a recent logger firmware; if you don't see the option, the logger is on an older build.)
If a Modbus device won't connect or scan, it's almost always the address, the baud rate, or (on RS-485) swapped A/B wiring. Confirm the address and baud you set on the device, and that the port's speed matches, before rescanning.
Step 3b - Auto-detected devices: pick the interface
Some devices (for example Solar MD CAN batteries) announce themselves on the bus, so there's no scan and no address to enter. On Interface Selection, choose the compatible port (e.g. CANBUS 1) and the LoggerV attaches to it - the port's status changes to Attached. Each interface option also has a Guide button that opens a physical-connection guide for that model.
If the wizard reports "No ... interface detected", the LoggerV has no free port of the type that device needs - check the wiring and the port.
Setting the interface speed
A port's speed is a property of the interface, not the device. On the interface's settings (the gear / Interface Settings), a serial port exposes Baud Rate (2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400), Data Bits, Stop Bits and Parity; click Change to apply. A CAN port shows its Bus Speed read-only.
A serial port can carry several devices. As the dialog warns, "altering these settings could affect other devices using this interface." Change the baud rate only when it's wrong for every device on that port.
Confirm the device was added
- On the Interfaces tab, the device appears under the port's Enabled devices: list.
- Under My Devices, it appears in its device-type group (e.g. Hybrid Inverters, Storage, Energy Meters), and opens on its live-data tab.
Open the device and check its live values are updating - that confirms the LoggerV is talking to it.
Adding a device from the Interfaces tab (alternative)
You can also add support per-port without the wizard: on the LoggerV's Interfaces tab, open the port's accordion pane and click Add Device. On success you'll see "Success add Device support for device ...". This is the fallback the app suggests when the logger firmware is too old for the wizard.
Who can do what
Adding a device is a commissioning task. The Add Device wizard itself isn't gated behind an elevated permission in the client - a signed-in user with access to the logger can run it. Some related actions are permission-gated (uploading a connection guide needs connection_guide; replacing device images needs Image_Upload; firmware and file-browser actions on the logger need their own permissions). In practice, adding devices is done by installers during setup.
Tips and gotchas
- Address and baud are set on the device, not in myPower24 - the app reads them, it doesn't push them. Note them before you leave the device.
- Auto-detected devices need no address - if you're hunting for an address field for a CAN battery, there isn't one; just pick the interface.
- One port, many devices - several Modbus devices can share one RS-485 port, each with its own address; they must all use the same baud rate.
- Use the model's help (?) icon in the wizard to open its KB page and confirm wiring and settings before you commit.
