What Is EcO Start + Connect?
EcO Start + Connect is iopool's complete smart water monitoring solution for one pool or hot tub treated with chlorine or bromine.
The system combines three essential components:
-
EcO Smart Water Monitor: A floating sensor that measures key water parameters.
-
iopool cOnnect Gateway: A Bluetooth/Wi-Fi device that enables remote access to EcO readings.
-
iopool App: Your pool care companion, displaying measurements and providing personalized maintenance recommendations.
The cOnnect gateway is already included in this solution. You do not need to purchase it separately.
What Does EcO Monitor?
EcO directly measures three important water parameters:
pH β Monitor Your Water Balance
pH indicates how acidic or basic your water is. Keeping it within the recommended range helps maintain swimmer comfort and supports effective water treatment.
ORP β Understand Disinfection Potential
ORP (oxidation-reduction potential), measured in millivolts (mV), provides an indication of the water's oxidizing and disinfecting potential.
ORP is not a direct measurement of free chlorine concentration in ppm. It should be interpreted alongside other water chemistry measurements.
Water Temperature β Stay Informed
EcO monitors water temperature, helping you follow temperature changes in your swimming pool or hot tub.
What Doesn't EcO Measure Directly?
EcO does not directly measure free chlorine concentration, cyanuric acid (CYA), total alkalinity (TA), calcium hardness, or salt concentration.
Additional water balance parameters can be checked using test strips and taken into account by the iopool app.
Learn more about the water parameters measured by EcO.
Remote Pool Monitoring with the Included cOnnect Gateway
Can you check your pool water when you're away from home? Yes. EcO Start + Connect includes the gateway needed for remote monitoring.
Here's how the connection works:
EcO sensor β Bluetooth β cOnnect gateway β Home Wi-Fi β iopool app
EcO communicates through Bluetooth Low Energy (BLE). The cOnnect gateway receives its readings and transmits them through your home Wi-Fi network, making them accessible through the app when the system is connected.
This means you can review your available water readings from work, while traveling, or wherever you have internet access.
What Do You Need for Remote Monitoring?
-
A 2.4 GHz home Wi-Fi network with internet access
-
An available power outlet for the cOnnect gateway
-
A location within Bluetooth range of EcO and Wi-Fi coverage
-
A compatible smartphone with the iopool app
Walls, pool covers, and other obstacles may affect Bluetooth communication. Remote updates depend on the gateway's connection and are not instantaneous.
For installation details, follow our iopool Wi-Fi gateway setup guide.
The iopool App β Water Readings and Personalized Pool Care

Which iopool Monitoring Solution Should You Choose?
Your pool treatment and the number of water bodies you want to monitor determine the right solution.
One chlorine- or bromine-treated pool or hot tub?
EcO Start + Connect is the standard choice, with one monitor and one gateway included.
One saltwater pool or hot tub?
Choose EcO Start SALT + Connect, designed for saltwater treatment systems. The SALT version monitors pH, ORP, and temperature; it does not directly measure salinity.
Two pools or hot tubs at the same location?
Discover the EcO Start Duo Pack for monitoring two pools or spas. It combines two standard EcO monitors with one cOnnect gateway, provided both water bodies and the installation are compatible.
Explore the iopool smart pool monitoring solutions to compare the available options.
Why ORP Matters for Pool Water Care
ORP helps you understand the water's oxidizing potential, which is relevant to disinfection.
Unlike a chlorine test, ORP does not tell you the free chlorine concentration in ppm. pH, stabilizer concentration, and other water conditions can influence how ORP readings should be interpreted.
EcO combines ORP monitoring with pH and temperature data to support informed water care decisions.
Regular water testing remains important. No single ORP measurement can guarantee that pool or hot tub water is safe for swimming.
