Merlin Reset

The newest Merlin versions (v33+) allows you to force reset all the Merlin settings to their defaults with an administrator, pre-registered user with password resiot1234.

In order to trigger the reset routine, create a reset file on a FAT32 formatted USB key and plug the key into your gateway. The reset procedure will then reset Merlin to its defaults settings. The operation could take up to two minutes.

In order to avoid reboot and reset loops, once complete, the reset procedure will rename your reset file to resiot.

The reset routine will:

  1. Remove previous ResIOT OpenVPN certificates
  2. Reset Cellular data if present
  3. Reset all existing user passwords and set the Administrator's password to resiot1234
  4. Reset the assigned gateway EUI
  5. Reset all grpc and secuity token settings
  6. Reset the network connection to static IP address:
  7. Restart the gateway
