OpenMediaVault tips

Installation

• recommended to use Debian installer and then the omv debian packages
• recommended to run omv-firstaid after omv packages installation.
• any additional disk, apart from the main one (the Debian/OMV installation one) must be added from the OMV interface. No manual /etc/fstab file edition is allowed. Otherwise you are not allowed to use those disks to share folders, etc. To incorporate the disks in OMV: 1. unmount and remove them from /etc/fstab, 2. Check the disk are available in Settings-Storage-Disks, 3. Go to Settings-Storage-File systems and mount (don´t create and mount) and configure as it was in the /etc/fstab file.

Video cameras

My Energeeks Sentinell III (Model: EG-CIP004) WiFi Camera is based on Tuya platform. It supports ONVIF protocol but is poorly documented.

By using nmap, I have discovered the open port: 888, and the default username: admin. If you want to configure it in Home Assistant: 0. (Enable the ONVIF feature from the Energeeks or Tuya mobile app, if it's the first time)

1. Add ONVIF integration in Settings.
2. Set the host ip-address, the port 888, the username admin, the password you set in the mobile app
3. Add the entity in the HA Dashboard.
