+title: "Activate timer mode"
+action: watts.activate_timer_mode
+domain: watts
+description: "Set a thermostat to timer mode with a target temperature and duration."
+---
+
+The **Activate timer mode** action sets a Watts Vision + thermostat to **Timer** mode with a target temperature and duration. When the timer expires, the thermostat returns to its previous mode.
+
+Use it when you want a temporary temperature boost, for example, to warm up a bathroom before a shower.
+
+{% include actions/ui_header.md %}
+
+To use this action in an automation or script:
+
+1. Go to {% my automations title="**Settings** > **Automations & scenes**" %}.
+2. Open an existing automation or script, or select **Create automation** > **Create new automation**.
+3. If you're setting up a new automation, add a trigger in the **When** section. Scripts don't need a trigger. They run when something else calls them.
+4. In the **Then do** section, select **Add action**.
+5. From the search box, search for and select **Watts Vision +: Activate timer mode**.
+6. Select the climate entity you want to control.
+7. Set the **Temperature** and **Duration**.
+8. Select **Save**.
+
+### Options in the UI
+
+{% options_ui %}
+Temperature:
+  description: Target temperature to hold while the timer is active.
+Duration:
+  description: Duration of the timer in minutes (1–1440).
+{% endoptions_ui %}
+
+{% include actions/yaml_header.md %}
+
+In YAML, refer to this action as `watts.activate_timer_mode`. A basic example looks like this:
+
+{% example %}
+action: |
+  action: watts.activate_timer_mode
+  target:
+    entity_id: climate.living_room_thermostat
+  data:
+    temperature: 21.5
+    duration: 90
+{% endexample %}
+
+This sets the living room thermostat to 21.5°C for 90 minutes, then returns to its previous mode.
+
+### Options in YAML
+
+YAML sometimes provides additional options for more complex use cases that are not available through the UI.
+
+{% options_yaml %}

+  description: >
+    Target temperature to hold while the timer is active.
