+
+The `dweet` sensor platform allows you to get details from your devices which are publishing their values to [Dweet.io](https://dweet.io/).
+
+To use Dweet.io in your installation, add the following to your `configuration.yaml` file:
+
+```yaml
+# Example configuration.yaml entry
+sensor:
+  platform: dweet
+  name: Dweet.io Temperature
+  device: THING_NAME
+  value_template: '{{ value_json.VARIABLE }}'
+  unit_of_measurement: "°C"
+```
+
+Configuration variables:
+
+- **device** (*Required*): Identification of the device (also known as `thing`).
+- **name** (*Optional*): Let you overwrite the the name of the device in the frontend.
+- **value_template** (*Required*): The variable to extract a value from the content.
+- **unit_of_measurement** (*Optional*): Defines the unit of measurement of the sensor, if any.

+
+You can easily send dweets from the commandline to test your sensor.
+
+```bash
+$ curl -H 'Content-Type: application/json' -d '{"temperature": 40, "humidity": 65}' https://dweet.io/dweet/for/ha-sensor
+```
+will give you a response like the one below:
+
+```json
+{"this":"succeeded","by":"dweeting","the":"dweet","with":{"thing":"ha-sensor","created":"2015-12-10T09:43:31.133Z","content":{"temperature":40,"humidity":65}}}
+```
+
+The [dweepy](https://github.com/paddycarey/dweepy) module gives you another option to work with [Dweet.io](https://dweet.io/).
+
+Send a dweet. 
+
+```bash
+$ python3
+>>> import dweepy
+>>> dweepy.dweet_for('ha-sensor', {'temperature': '23', 'humiditiy':'81'})
+{'thing': 'ha-sensor', 'created': '2015-12-10T09:46:08.559Z', 'content': {'humiditiy': 81, 'temperature': 23}}
+```
+
+Recieve the latest dweet.
+
+```bash
+>>> dweepy.get_latest_dweet_for('ha-sensor')
+[{'thing': 'ha-sensor'', 'created': '2015-12-10T09:43:31.133Z', 'content': {'humidity': 65, 'temperature': 40}}]
+```
