How to check the firmware and hardware version on the Zelio Logic Smart relay?

  • Check the firmware on the front of the screen (LCD display) of Zelio Smart Relay.


  • Check the firmware on the software, Zelio Soft 2.

  • Check the hardware version (printed on the right side of the modules):
• If the firmware is 4.04 or higher, you MUST use Zelio Soft 2 V4.4 or higher
• if the firmware is 4.03 or lower, you can use any version of Zelio Soft 2 but we strongly recommend you to update your Zelio Soft 2 as soon as possible to the last version in order to avoid any future compatibility issue.
