Clyr inline pH/ORP/Temp probe install

Add the 3-in-1 inline probe, plumb the flow cell, and register the pH and ORP sensors in the Clyr app.

This guide walks through installing the inline pH/ORP/temperature probe, plumbing the flow cell bypass, and onboarding both sensors inside the Clyr mobile app.

Tools required to install the inline pH/ORP/temperature probe. — Gather the probe, tubing, and hand tools before you begin.

Tools needed

Set everything out up front so you do not need to leave the pad mid-install.

Clyr Lite or Clyr Controller
Clyr 3-in-1 inline pH/ORP/temperature probe with flow cell
Ethernet or 4-wire copper cable
Small flathead screwdriver
Large Phillips screwdriver

Step 1 - Connect your controller

Confirm the Clyr Controller is powered, online, and assigned to the correct pool location before making changes to the plumbing.

Follow the controller connection guide if the controller is not yet installed.

Step 2 - Locate installation point

Find a straight section of pipe after the filter and before any heaters or chlorinators. The flow cell saddle clamps need roughly one foot of space to sit level for proper sampling.

Technician positioning the flow cell saddle clamps on a return pipe. — Choose a straight run after the filter where the flow cell can sit level.

Step 3 - Turn off breaker to main pump

Turn off the pump breaker before opening the plumbing. Removing pressure from the line stops water from erupting while you drill into the pipe.

Shut off the pool pump breaker and verify that the circulation system is depressurized before moving on.

Step 4 - Drill holes for water flow to flow cell

Use a 1/8-inch drill bit to add two holes on the top of the pipe inside the saddle clamp footprint. Install the clamps over the holes so the quick-connect fittings align with the openings.

Do not plumb the bypass after a chlorinator or salt cell.

Step 5 - Connect tubing

Snap the flow cell onto the pipe between the clamps. Route tubing from the upstream saddle clamp to the bottom port on the flow cell, and from the top port back to the second hole so water returns to the line.

Flow cell attached to the pipe with tubing connected between the saddle clamps. — Connect the inlet tube to the bottom port and the outlet tube to the top port.

Step 6 - Turn breaker back on and test water flow

Restore power to the pump but leave the sensor removed so water can purge air from the flow cell. You are aiming for a gentle bubbling fountain—not a solid jet of water.

If the return stream is too strong, cut the outlet tube and add the blue flow limiter valve to tame the flow.

Step 7 - Configure probe in app

In the Clyr app, open the pool location, choose Settings → Devices → Add → Pool Equipment, and add the probe as two sensors. Start with the pH sensor, then repeat the same process for ORP.

Use network 1 for terminals A1/B1 or network 2 for A2/B2, matching how you wired the probe leads.

Even though the inline probe combines pH and ORP, you must add each sensor as its own component in the app.

Adding a pH sensor from the devices screen in the Clyr app. — Add the pH sensor first, selecting the network that matches your wiring.

ORP sensor listed in the add equipment view of the Clyr app. — Repeat the process for ORP so both sensors appear on the devices list.

Step 8 - View sensor data

Open the Water Quality tab, tap Refresh Data, and wait a few seconds for the latest readings. Both pH and ORP values should update shortly after the refresh completes.

Active pH, ORP, and temperature readings on the Water Quality tab in the Clyr app. — Refresh the Water Quality tab to confirm both probes are reporting.

Next steps

With the inline probe online you can build automation with schedules, programs, or autopilot features in the app.

Troubleshooting

The sensors are wired but no readings appear. Check that every probe lead is firmly seated in the controller terminals.
The app shows dashes instead of values. Verify the probe has at least 9 V between the red and black wires. Low voltage prevents the probe from transmitting.
Values still will not refresh. Confirm you added both sensors to the app on the same RS485 network you used when wiring.
