Your sensor
Radiant Waves reads your Ondilo ICO through Ondilo's own API. Link the account once and the sensor is connected for good — refresh tokens don't expire, so you shouldn't have to come back here.
Link your Ondilo account
You'll be sent to Ondilo's own sign-in page. Radiant Waves never sees your password — Ondilo hands back a token that only allows reading your pool data.

1
Have the ICO set up in the Ondilo app
The float needs to be paired to your Wi-Fi and reporting in Ondilo's own app first. Radiant Waves reads what the app already sees; it doesn't pair the hardware itself.

2
Sign in with your mobile app password
This trips most people up: the password for the Ondilo website is usually a different one and won't work here. Use the credentials you use in the phone app.

Approve read access
Ondilo will ask you to authorise Radiant Waves. Approve it and you'll land back here with your pool detected.
If the sensor goes quiet
- Check the ICO is still floating and hasn't drifted under a cover or into a skimmer.
- Look at the Wi-Fi signal above. Weak coverage at the pool is the usual cause of gaps in the chart — a mesh node or outdoor extender within sight of the water fixes it.
- Check the battery. Below 10% the ICO shuts down and stops reporting entirely.
- Confirm the Ondilo app itself still shows recent readings. If the app is stale too, it's the sensor or the network, not this site.
