 External automotive relays remain a good upgrade path for higher-current loads.

+## Current Relay Switching Decision
+
+For the current Starlink Mini and fridge use case, the built-in ESP32 relay board relays are the planned switching method.
+
+Use positive-side switching:
+
+    Battery +
+        |
+      Fuse
+        |
+      Relay COM
+        |
+      Relay NO
+        |
+      Load +
+
+    Load -
+        |
+      Ground bus
+
+External automotive relays are reserved for future higher-current loads.
+
+## DS18B20 Final Install Direction
+
+Temporary Wago wiring proved one probe, but final install should use a proper terminal/distribution board.
+
+Recommended:
+
+    3.3V bus
+    DATA bus
+    GND bus
+
+With:
+
+    4.7k resistor between DATA and 3.3V
+
+Only three wires need to return to the ESP32:
+
+    3.3V
+    GPIO4
+    GND
