Clyr
Clyr controller and monitoring gear on equipment pad
DIY-friendly automation

Build the pool brain you always wanted

Clyr Monitoring and chemistry control expose open APIs, webhooks, and local dashboards so makers can add dosing, sensors, and custom automations without buying into a closed ecosystem.

No vendor lock-in

We built Clyr to be the pool health system anyone can extend

REST APIs, MQTT streams, and real-time webhooks expose chemistry, equipment state, and alerts so you can script anything—from Home Assistant automations to a custom mobile app.

  • API keys on request: Builder- and DIY-friendly auth with scoped permissions.
  • Hardware agnostic: Use our probes or pipe data into the gear you already own.

What makers build

From custom dashboards to robotic skimmers

Tap into chemistry telemetry, relay controls, and CO2 dosing to script your own workflows. The open data model means you can extend Clyr instead of fighting it.

Popular DIY projects

  • • Home Assistant cards with live pH, ORP, and pump RPM.
  • • Custom dosing logic that blends Clyr telemetry with weather APIs.
  • • Slack/Discord bots that alert roommates when it's time to backwash.

Do it without breaking the bank

Upgrade chemistry and control on a DIY budget

Order the monitoring bundle, add CO2 or liquid dosing when you're ready, and keep the automations you love. No subscription required to access your own data.
