### JSON attributes topic configuration
The example sensor below shows a configuration example which uses a JSON dict: `{"ClientName": <string>, "IP": <string>, "MAC": <string>, "RSSI": <string>, "HostName": <string>, "ConnectedSSID": <string>}` in a separate topic `home/sensor1/attributes` to add extra attributes. It also makes use of the `availability` topic.
The example sensor below shows a configuration example which uses the following separate topic and JSON structure to add extra attributes.
Topic: `home/sensor1/attributes`
```json
{
"ClientName": <string>,
"IP": <string>,
"MAC": <string>,
"RSSI": <string>,
"HostName": <string>,
"ConnectedSSID": <string>
}
```
It also makes use of the `availability` topic.
Extra attributes will be displayed in the frontend and can also be extracted in [Templates](/docs/configuration/templating/#attributes). For example, to extract the `ClientName` attribute from the sensor below, use a template similar to: {% raw %}`{{ state_attr('sensor.bs_rssi', 'ClientName') }}`{% endraw %}.

### JSON attributes template configuration
The example sensor below shows a configuration example which uses a JSON dict: `{"Timer1":{"Arm": <status>, "Time": <time>}, "Timer2":{"Arm": <status>, "Time": <time>}}` on topic `tele/sonoff/sensor` with a template to add `Timer1.Arm` and `Timer1.Time` as extra attributes. To instead only add `Timer1.Arm`as an extra attribute, change `json_attributes_template` to: {% raw %}`"{{ {'Arm': value_json.Timer1} | tojson }}"`{% endraw %}.

If you are using the [OwnTracks](/integrations/owntracks) and enable the reporting of the battery level then you can use an MQTT sensor to keep track of your battery. A regular MQTT message from OwnTracks looks like this:
```bash
owntracks/tablet/tablet {"_type":"location","lon":7.21,"t":"u","batt":92,"tst":144995643,"tid":"ta","acc":27,"lat":46.12}
Topic: `owntracks/tablet/tablet`
```json
{
"_type": "location",
"lon": 7.21,
"t": "u",
"batt": 92,
"tst": 144995643,
"tid": "ta",
"acc": 27,
"lat": 46.12
}
```
Thus the trick is extracting the battery level from the payload.

If you are using a DHT sensor and a NodeMCU board (esp8266), you can retrieve temperature and humidity with a MQTT sensor. A code example can be found [here](https://github.com/mertenats/open-home-automation/tree/master/ha_mqtt_sensor_dht22). A regular MQTT message from this example looks like this:
Topic: `office/sensor1`
```json
office/sensor1
