Collidera Quick Start Guide

Welcome to Collidera. This guide walks you through setting up your hamster activity tracker and recording your first wheel spins.

What is in the package?

Collidera receiver with LCD screen and Wi-Fi
Wheel rotation sensor with cable and 3.5 mm audio jack
Sensor holder for cage bars
Neodymium magnet, wrapped in protective red bubble wrap

You will also need a USB C cable and power supply.

The Collidera kit laid out: receiver with LCD screen, wheel sensor with cable and audio jack, sensor holder, and the magnet in red bubble wrap

Install the Collidera app

Download the Collidera app from the App Store or Google Play.

Open the app and sign in with your email address. You will receive a one-time verification code by email — there is no password to create.

Create a profile for your hamster, including its name.

Connect your Collidera receiver

Connect the receiver to power using USB C.
Wait for the device to start. The LCD screen should turn on.
In the app, open your pet profile. At the bottom you will see a Pair Sensor button — tap it.
The app starts scanning for nearby sensors. Tap your sensor when it appears in the list, then tap Pair Sensor to confirm. The screen on the receiver should change.
Back in the app, tap Configure Wi-Fi and enter your home network name (SSID) and password.
Once the connection succeeds, WIFI appears in green on the receiver.

Install the wheel sensor

Unwrap the neodymium magnet from its protective red bubble wrap.
Attach the magnet securely to the outside of your hamster's exercise wheel, where your hamster cannot reach it.
Attach the sensor holder to the cage bars near the wheel.
Insert the sensor into its holder.
Position the sensor so the magnet passes close to it once per wheel rotation.
Connect the sensor cable's audio jack to the Collidera receiver.

Test your setup

Gently rotate the wheel by hand.
Every full rotation should increase the spin counter on the receiver by one.
If spins are not registering, adjust the distance between the magnet and the sensor and try again.

Start tracking

Your Collidera is ready. When your hamster uses the wheel, Collidera records the activity automatically.

Open the app to follow your hamster's activity and explore the recorded statistics.

A finished setup: sensor and magnet on the wheel, cable running to the receiver, which shows live distance, spin count and an hourly chart — A finished setup, receiver already reporting spins

Reading the receiver screen

Three bottom-row words tell you what the receiver is doing at a glance. Here is what each screen looks like, and what the colours mean.

Receiver screen showing a device name, a spin counter at zero, and the hint Pair with Collidera app — **Unpaired.** Fresh out of the box. It still counts spins on its own — the app just has not claimed it yet.

Receiver screen showing a pet name, an empty chart, and WIFI in blue while connecting — **Paired, Wi-Fi connecting.** Right after pairing, while you enter your network name and password in the app.

Receiver screen showing a pet name, live stats, a populated 24-hour chart, and WIFI and SENSOR both in green — **Running.** Paired, connected, and recording — the state you want to see day to day.

BLE gray — no phone connected over Bluetooth (normal once set up) green — the app is actively connected, which only happens while pairing or configuring

WIFI red — not connected blue — connecting green — connected and syncing

SENSOR red — no wheel sensor detected green — sensor connected and reporting

WIFI only appears once the receiver is paired — the unpaired screen has no slot for it.
