HYDROS Online Manual HYDROS Control Updating to the Latest Firmware

Updating to the Latest Firmware

If your HYDROS Control requires a firmware update, the app will notify you of such as soon as the app starts. So you can go ahead and do the firmware update without any issues.

WARNING: ALWAYS check your output overrides after a firmware update. We do everything possible to ensure the overrides survive the firmware upgrade and reboot, but it is always best to take the time and ensure all your overrides are correct.

Step 1: Restart the Devices

We highly recommend that before the update, you restart your devices.

  1. Tap on the upper-RIGHT-hand corner of the STATUS screen and select “Device Properties.”
  2. If you have only one device, tap on “Reboot Device.”  If you have a collective, tap on the “Reboot Collective” button.
  3. Wait until your devices are back up and you can access the STATUS screen.

Step 2: Download the Update

The HYDROS control allows you to download the update file WITHOUT installing it. It comes in handy when you are not home and want to download the update, so you can install it right away when you get home. Also, if the download fails, your unit will not lock up. Instead, it will fail the download, which you can manually restart.  

TIP: It is best to download the firmware on ALL devices before installing it on ANY device. It will ensure all devices use the same firmware version and prevent having incompatible firmware on the same collective.
  1. Tap on the upper-RIGHT-hand corner of the STATUS screen and select “Device Properties.”

  2. Scroll down and tap on “Firmware Update.”

  3. Tap on the right-hand side button to download the latest release version
    TIP: . The right-hand button shows the latest firmware. If you do not see the latest version available, try power cycling your Control unit.

  4. Wait for the file to download fully.

Step 3: Install the Update

Once the file has been downloaded, you need to install it manually. This method is handy when you have multiple units to update. You can download all updates first and then install them simultaneously.

WARNING: DO NOT install firmware updates while you are away. ONLY install firmware updates when you are in the exact location as the unit
  1. Tap on the LEFT-side button to install the firmware version you just downloaded

  2. The unit will restart with the new firmware version.
  3. Completely close the app and restart it so it pulls the latest information from the unit. 

Step 4: Manually Power Cycle Devices

After installing a new firmware, it is always good to manually power cycle a device.

  1. Wait 2 minutes after installing the firmware.
    WARNING: If you power cycle the units BEFORE the 2 minutes, your HYDROS will revert to the previous firmware
  2. Unplug from the power you HYDROS Control, wait 10 seconds, and power it again.
  3. Unplug from power your HYDROS WiFi Strips, wait 10 seconds and power them again.

Appendix A: Reverting to a previous firmware

Method A: App
