Gateway E32-V2
There is a small button on the top of the circuit board near the Espressif module called ‘RST’. If you press it for 10 seconds, you device will restart and reset all settings to factory default.
The Gateway needs to be connected to power (EMS service jack, USB-C or 12V DC power supply) in order for the reset to work.
If you don’t want to open the enclosure, just flash the firmware again via the USB-C connector.

Gateway Premium II and older
The Gateway Premium does not have a reset button. Although there is a button on the Wemos called ‘reset’, it’s actually just a reboot button.
Pressing it will only restart the Wemos, it does not reset anything.
If you are on firmware 2.2.2b0 you can use a metal pin to shortcut pins D3 to D2 on the Wemos for 10 seconds to reset EMS-ESP.
The Gateway needs to be connected to power (EMS service jack or Micro USB) in order for the reset to work.
