+**Always update with commandline!!!!**

 To that end, it's advantageous to remove zypper hook into Discover. Native packages should **not** be updated with it and notifications become useless:

+===== Bluetooth =====
+==== On log in ====
+Make a .desktop file in the ~/.config/autostart directory with the command:
+  /bin/sh -c 'bluetoothctl connect E8:07:BF:3C:06:F0'
+==== On wake up from sleep ====
+Having specifik devices connect on bluetooth when logging in or waking from sleep requires a systemd service.
+Make a script with contents:
+  sudo nano /usr/local/bin/bluetooth-reconnect
+<code bash>
+#!/bin/sh
+LOCK_FILE="/tmp/bluetooth-wakeup.lock"
+# LOG_FILE="/var/log/bluetooth-wakeup.log"
+# Exit if another instance is running
+#if [ -f "$LOCK_FILE" ]; then
+  # echo "Script already running, exiting." >> "$LOG_FILE"
+#  exit 0
+#fi
+# Create lock file
+# echo $$ > "$LOCK_FILE"
+# trap 'rm -f "$LOCK_FILE"' EXIT
+# Log the start of the script
+# echo "Bluetooth wakeup script started at $(date)" >> "$LOG_FILE"
+# Wait for the Bluetooth adapter to initialize (max 10 seconds)
+MAX_RETRIES=10
+RETRY_DELAY=1
+for i in $(seq 1 $MAX_RETRIES); do
+  if bluetoothctl show | grep -q "Powered: yes"; then
+    echo "Bluetooth adapter is powered on, attempting to connect..." >> "$LOG_FILE"
+    bluetoothctl connect E8:07:BF:3C:06:F0
+    if [ $? -eq 0 ]; then
+      # echo "Successfully connected to Bluetooth device" >> "$LOG_FILE"
+      exit 0
+    else
+      # echo "Failed to connect to Bluetooth device (attempt $i)" >> "$LOG_FILE"
+      sleep $RETRY_DELAY
+    fi
+  else
+    # echo "Bluetooth adapter not ready, retrying in $RETRY_DELAY seconds... (attempt $i/$MAX_RETRIES)" >> "$LOG_FILE"
+    sleep $RETRY_DELAY
+  fi
+done
+</code>
+Then make a system ini file:
+  sudo nano /etc/systemd/system/bluetooth-wakeup.service
+<code ini>
+[Unit]
+Description=Reconnect Bluetooth after wakeup from sleep
+After=suspend.target hibernate.target hybrid-sleep.target
+[Service]
+Type=oneshot
+RemainAfterExit=no
+ExecStart=/usr/local/bin/bluetooth-reconnect
+[Install]
+WantedBy=suspend.target hibernate.target hybrid-sleep.target
+</code>
+Note that adding **WantedBy=multi-user.target** is for logging in, and could potentially make autostart not needed. Untested, probably affected by **After** so more work needed.
