-Binary sensors are gathering information about state of switches, contacts, pins, and alike. The return value of those sensors is usually digital (1/0). This means that those sensors knows only two states: **off/low/open*** and ***on/high/closed**.
+Binary sensors are gathering information about state of switches, contacts, pins, and alike. The return value of those sensors is usually digital (1/0). This means that those sensors knows only two states: **off/low/open** and **on/high/closed**.
+
+Knowing that there are only two states allows Home Assistant to represent the sensor better in the frontend.

+## {% linkable_title Processing JSON %}
+
+The MQTT switch and sensor platforms support processing JSON over MQTT messages and parse them using JSONPath. JSONPath allows you to specify where in the JSON the value resides that you want to use. The following examples will always return the value `100`.
+
+| JSONPath query | JSON |
+| -------------- | ---- |
+| `somekey` | `{ 'somekey': 100 }`
+| `somekey[0]` | `{ 'somekey': [100] }`
+| `somekey[0].value` | `{ 'somekey': [ { value: 100 } ] }`
+
+To use this, add the following key to your `configuration.yaml`:
+
+```yaml
+switch:
+  platform: mqtt
+  state_format: 'json:somekey[0].value'
+```
+
+More information about the full JSONPath syntax can be found [here][JSONPath syntax].
