   * **Step 2.** Disable Auto updates. See Settings -> Firmware -> Online updates in Remote Console.
   * **Step 3.** Download the latest Venus-OS Extended image from the last comments on [[https://github.com/victronenergy/venus/issues/378|this issue]].
+  * **Step 4.** Install that file using the [[ccgx:firmware_updating|GX Offline install method]]. Requires a USB-stick or Micro SD-Card.
+  * **Step 5.** Verify that the image was successfully installed: go to Settings -> Services, and check that Signal K and Node-RED are now available to enable.
+  * **Step 6.** Enable either Signal K or Node-RED. Note that though its possible to enable both, doing so on a Venus GX is "pushing it", the system might become slow. Installer access level is required to enable/disable these servers, see Settings -> General.
+  * **Finished**. The Venus OS Extended image has now been installed successfully. Continue in either the Node-RED or the Signal K chapter below.

 Make sure that there is always 30MB of free space remaining on the data partition. TODO: how can a user see that? Also mem usage / mem free & some cpu stats would be nice to see. Maybe with a dashboard & flow? ;o)
+==== 4.3 Controlling relays ====
+=== GX Device relays ===
+Controllable, make sure to configure them to be Manually controlled.
+=== MPPT Relay ===
+Note that while there is a Victron node that offers to control the relay in a solar charger (only large solar chargers have a relay!), its currently not workable since VictronConnect does not offer the required "Manual control" option in the list of selectable Relay modes for the MPPTs. This will be fixed at some point.
+=== BMV Relay ===
+Currently not possible, the driver in Venus OS doesn't support controlling it. This will be fixed at some point.
+=== Multi & Quattro Relays ===
+Includes alarm relays as well as the AC-out 2 relay: its not possible to control those; and there is no plan to make them controllable from within Node-RED.
