After the update finishes, the device will restart. Do not turn off the power during this process. Troubleshooting Common Firmware Issues
Firmware updates for the LSW-3 can be performed through two primary methods:
Navigate to the Serial Port Settings page in the LSW3 interface. Ensure the baud rate matches your inverter specs (typically 9600 or 115200 , with 8 Data Bits, 1 Stop Bit, and No Parity). 3. Brick Recovery (Device Unresponsive) lsw3 firmware
, a popular WiFi data logging device used with solar inverters from brands like , Deye , and INVT . This firmware manages how the logger collects Modbus data from your inverter and transmits it to cloud platforms or local smart home systems like Home Assistant .
Wait 2 to 5 minutes. The stick will automatically reboot. Once the AP_XXXXX network reappears in your Wi-Fi settings, the process is complete. 5. Troubleshooting Common LSW3 Firmware & Connection Issues After the update finishes, the device will restart

If your solar platform migrates from an older server architecture to a newer global cloud, a firmware update ensures the stick points to the correct DNS endpoints. Ensure the baud rate matches your inverter specs
Custom smart home implementations (like the Home Assistant SOLARMAN Integration ) query the logger directly via Modbus TCP. Certain firmware versions introduce high request timeouts, requiring a specific downgrade or upgrade to stabilize.
