Commonly asked questions

What if I am not satisfied?

There is little chance that this will happen because trying an EcO is adopting it! However, if you were not completely satisfied, don't worry: we offer a "Satisfied or refunded" guarantee valid for 30 days after purchase.

Can I use the probe with another brand of products than iopool?

Yes. However, for the best experience, we recommend using the iopool brand as our recommendation engine is based on our products.

What is the lifespan of the probe?

EcO has a lifespan of 2 years, after which you will have to order a replacement module including a new battery and sensors. Buying this module extends the warranty for two more years.

What is the warranty period of the probe?

The EcO probe is guaranteed for 2 years from the date of purchase.

Do I need to pay for any subscription?

No. You can access all functionalities without any subscription, including customer assistance by chat.

Can I access my data all around the world?

This is possible by purchasing an iopool Bluetooth / Wi-Fi Gateway. By default, EcO uses Bluetooth Low Energy (BLE) technology to send data to your smartphone, so you have to be near the pool (approx. 9 m).

Which parameters are monitored by the probe?

The analysis parameters of the EcO probe are:

  • The water temperature;
  • The disinfection capacity (Redox capacity, ORP);
  • The pH (hydrogen potential).

Moreover, thanks to the initialization process, our calculation algorithms have 3 important parameters:

  • The hardness of the water;
  • The alkalinity of the water;
  • The amount of stabilizer (cyanuric acid level).

Your question is not on the list?

Consult the dedicated section of our FAQ or contact us via in-app support or on the website.


After initialization, you can't get EcO out of the water. See this article for more information.

Avis top

Très bon achat et une gestion bien meilleure de la piscine maintenant

Raphaël Laborde

Mon eau a tourné après quatre jours d'utilisation, la sonde ne m'a jamais demandé de rajouter du chlore.
Je mets donc trois étoiles en attendant une utilisation plus poussée.

Bonjour Raphaël,

Pourriez-vous nous contacter à l'adresse ? Nous pourrons ainsi vous aider au mieux.

Bonne journée,
L'équipe iopool

L'appli a planté, pas très pro

Bonjour Marc,

En effet, la nouvelle mise à jour a présenté un bug au démarrage pour les appareils munis de Android 12. Ce but a été réglé dans la journée.

Veuillez nous excuser pour cet inconvénient.

Bonne journée,
