+### Scheduled actions
+Although ESPHome doesn't have a Scheduler component, it is possible to use the timer to schedule actions and this is entirely managed in the device, so it will work even if Home Assistant and/or the Wi-Fi are unavailable.
+Following some examples:
+#### Scheduled relay
+```yaml
+# Scheduled relay
+time:
+  - id: !extend time_provider
+    on_time:
+      - hours: 7
+        minutes: 30
+        seconds: 0
+        then:
+          - switch.turn_on: relay_1
+      - hours: 12
+        minutes: 15
+        seconds: 0
+        then:
+          - switch.turn_off: relay_1
+      - hours: 19
+        minutes: 0
+        seconds: 0
+        then:
+          - switch.turn_on: relay_1
+      - hours: 23
+        minutes: 30
+        seconds: 0
+        then:
+          - switch.turn_off: relay_1
+```
+#### Scheduled climate
+> This requires add-on climate to be installed
+```yaml
+# Scheduled climate
+time:
+  - id: !extend time_provider
+    on_time:
+      - hours: 7
+        minutes: 0
+        seconds: 0
+        then:
+          - climate.control:
+            id: thermostat_embedded
+            mode: auto
+            target_temperature: 22°C
+      - hours: 19
+        minutes: 0
+        seconds: 0
+        then:
+          - climate.control:
+            id: thermostat_embedded
+            mode: auto
+            target_temperature: 20°C
+      - hours: 23
+        minutes: 0
+        seconds: 0
+        then:
+          - climate.control:
+            id: thermostat_embedded
+            mode: auto
+            target_temperature: 18°C
