+The `telnet` switch platform allows you to control devices with telnet commands.
+
+To enable this switch, add the following lines to your `configuration.yaml` file:
+
+```yaml
+# Example configuration.yaml entry
+switch:
+  platform: telnet
+  switches:
+    projector:
+      resource: "host_or_ip"
+      port: 4002
+      command_on: "PWR ON"
+      command_off: "PWR OFF"
+      command_state: "PWR?"
+      value_template: '{{ value == "PWR=01" }}'
+```
+
+Configuration variables:
+
+- **switches** (*Required*): The array that contains all switches.
+  - **identifier** (*Required*): Name of the switch as slug. Multiple entries are possible.
+    - **resource** (*Required*): Host or IP of the device.
