Perform any Updates

Keep Home Assistant Updated

• Click on Settings down the bottom left of the screen, and then update any components that require updating. If the system asks you to reboot, proceed and reboot. In this case there are three updates required. Note that pending updates are displayed at the top of the page, but if there are none, there will be nothing to see.

Keep Energy Manager Updated

New features and bug fixes are released through Energy Manager's own update system. Your Home Assistant will check the Energy Manager update server daily at 6am. If there is an update waiting, you will be notified. It won't install the updates automatically, so you can control when they are done as often a reboot of your Home Assistant will be required (especially if there are any modbus updates).

For this exercise we will check for updates manually and then we will update Energy Manager.

Browse to the PV menu, then to the update icon

You will be shown the following view:

1. This section shows you your current update status. Note that it will say Up to date when you first visit this page, as currently it has not checked to see whether there are updates waiting or not.
2. The first time we use this update page, we will be shown the large Generate SSH Key button. This will disappear once we have generated the SSH key (see below).
3. The Check Updates button will fetch the latest manifest to see if there are updates waiting for your system.
4. The Install Update button will allow you to install an update if there is one available.
5. The Force Reinstall button will allow you to redownload the same version again. This is handy when you muck up a file and something starts going wrong, this can reset EM to the default files for this current version.

Configuration of the update process, required once

To be able to update certain files in Home Assistant, the SSH add-on (pre-installed) is required to run in the background. For this to work we will need to create an SSH key.

Click on the large Generate SSH Key button

The following will be displayed:

Copy the entire code that is displayed (both lines) and then perform the following:

Click on Settings on the left menu

Click on Add-ons

Then click on Advanced SSH & Web Terminal

Up the top you will see four tabs. Click on the one called Configuration

We will update the Options box at the top:

Paste in the SSH key that was copied from an instruction above, as per the screenshot below. While you're at it, change the password there as well.

Once pasted in following the format in the screenshot above, press SAVE at the bottom of the Options box (not the save button at the bottom, it must be the top one which is within the same Options section ).

Press RESTART when prompted.

Once restarted, return to the Updates page (PV Menu > Updates) and the click on the large Done - Hide This Message button.

The page will change and just show the following three sections:

Select the Check Updates button and it will turn orange and also create a notification (you can just dismiss this).

If there is an update available, a notification simlar to below will be created, along with details of what is contained in the new update.

The Available Version will be updated in the upper box:

Select the Install Update button to start the update:

Once the update has completed, a notification similar to the following will be displayed.

You can dismiss this notification and you must restart Home Assistant for the changes made in the update to take effect.
