Before OTA make sure to go through the list below:

  • It is recommended to update the device in the IDLE mode without receiving and executing any commands from Modbus, Enapter Cloud, Enapter Mobile App, Web GUI or others.
  • Make sure you have physical access to the device before starting the update process.
  • Do not power off the device during the firmware update.
  • Remove Dryer Control Network before updating the firmware.
  • If Site has Enapter Gateway it needs to be updated to version 1.8.9 or higher.

# Known Bugs List

The list below contains the most important problems in the firmware and their solutions.

  • It is an issue (opens new window) using WiFi and Windows to access the .local hostname.

    Solution: Use a local ethernet connection to the electrolyser or IP address as a hostname.

  • DCN may assign an IP address to devices (computers, mobiles) connected to Wi-Fi AP associated with DCN enabled Enapter devices.

    Solution:

    • Delete the DCN from the Enapter Mobile App and create it one more time.
    • If it is possible try to separate the DCN from your main network environment by connecting the DCN to another WiFi AP. It is no need to separate one DCN from another.
