+
+[Flipr](https://www.goflipr.com) is a smart pool monitor that publishes data to the cloud via SigFox.
+Flipr sends data like ph, chlorine or temperature to a cloud server on a regular basis in order to monitor your pool.
+This integration gives you access to this information on Home Assistant in addition to the vendor's smartphone application.
+
+There is currently support for the following information within Home Assistant:
+
+- Chlorine Level
+- pH
+- Water Temperature
+- Red OX Level
+- Last measure date
+- pH Status Indicator
+- Chlorine Status Indicator
+
+## Prerequisites
+
+You will need to use the standalone app for this device to register a username and password.
+
+- [Google](https://play.google.com/store/apps/details?id=com.goflipr.flipr)
+- [Apple](https://apps.apple.com/fr/app/flipr/id1225898851)
+
+{% include integrations/config_flow.md %}
+
+## Tips
+
+It is recommended that you create your own card with the following sensors where \[fliprid\] is the id of your flipr:
+
+- `sensor.flipr_[fliprid]_chlorine`
+- `sensor.flipr_[fliprid]_ph`
+- `sensor.flipr_[fliprid]_red_ox`
+- `sensor.flipr_[fliprid]_water_temp`
+- `sensor.flipr_[fliprid]_date_measure`
+
+Leave `binary_sensor.flipr_[fliprid]_ph_status` and `binary_sensor.flipr_[fliprid]_chlorine_status` as badges.
