SEN0358 Factory Reset
Technogeek 2026-05-24 00:33:40 197 Views1 Replies I have a SEN0358 that's giving issues and I would like to know if there's a way to factory reset it. I may have inadvertently changed either the devices address or baud rate and so I cannot access any of the units registers. What the new address or baud rate may be I have no idea and so I would like to try resetting it before giving up and chucking it in the garbage.
Thanks
Hi, you may be able to recover it through Modbus registers.
If only the module address is unknown, write the desired address to the Module Address Register `0x02` using the broadcast address `0x00`. The valid address range is `0x0001-0x00F7`, and the default is `0x000C`. Note that broadcast commands do not return a response, and the new setting is saved after power-off and takes effect after restarting.
If the baud rate may also have been changed, start with the default `19200` first. If that does not work, try the supported baud rates: `2400`, `9600`, `14400`, `19200`, `38400`, `57600`, and `115200`. Once you find the working baud rate, you can write the baud-rate register `0x03` back to the desired value, then power-cycle the sensor.
