Overview

Software Updates are delivered in a different way depending upon the type.

System Updates

How system updates reach you depends on how your system was set up.

Nomad Appliance

On the Nomad Appliance, Sensa looks after updates for you. By default your system keeps itself up to date automatically, so there is usually nothing to do. Updates are delivered by us, so they need a live support plan.

If you would rather decide when updates happen, the admin login can manage this in Settings, Supervisor, under Software updates:

• turn the automatic updates off and use the Update now button when it suits you,
• pick a maintenance window, a time of day when updates are allowed to run, so they never interrupt you on the road. One window covers both your Sensa updates and your system's operating system updates, because the question you are really answering is when you are not using the van,
• read the release notes and see the download size before you apply an update.

Updates move forward only. If you ever need to go back to an earlier version, you restore from a backup, see Rollback.

Your system backs up first

Every update starts with a backup. Before anything is installed, your system takes a full snapshot and waits for it to finish, so there is always a recent point to return to. On the hardware we ship this takes several minutes, and the update panel says Backing up before updating while it runs.

Press Update now once and let it work. There is nothing to watch: the update carries on by itself, your system restarts at the end, and the page reconnects on its own.

If a backup is already being written, the overnight one for example, the update waits rather than starting alongside it, and tells you to try again once it has finished. See Backups.

Enthusiast and DIY

On an Enthusiast or DIY system you look after updates yourself. When a new update is available it appears in Home Assistant, and you download and apply it there in the usual way. On Enthusiast you also look after your own backups.

Device Firmware Updates

All devices are configured in the firmware to check every 12 hours for new firmware in the stable stream on our Sensa Cloud system. If a new firmware is detected, this will be shown in Home Assistant and you will be given the option to download and update the firmware.
