Quick Start Guide

Install Float Switches

Mount the included float switches in your tank at desired alarm levels. Connect to Transmitter terminals (Float 1: white/black, Float 2: white/black).

Power Up Transmitter

Connect USB-C power (or solar panel) to the Transmitter near your tank. OLED display will show boot screen and float status.

Power Up Receiver

Connect Receiver to power indoors. Within 30 seconds, it should receive data from the Transmitter (display shows “Last Packet”).

Connect to WiFi

On your phone, connect to “FloatMasterAP” WiFi network. Browser opens automatically (or go to 192.168.4.1). Enter your home WiFi credentials.

Visit app.floatek.ca/register and enter your Device ID (shown on Receiver display). Create your account.

Test Your System

Manually raise/lower float switches. Verify LED turns red, buzzer sounds, and dashboard updates. Set float modes (HIGH/LOW) as needed.

Float Modes

Each float switch can be configured independently for HIGH or LOW alarm mode.

HIGH Alarm Mode

Use for: Septic tanks, sump pits, overflow prevention
Triggers when: Water rises and lifts float UP
Action: Time to pump or check drainage

LOW Alarm Mode

Use for: Cisterns, water storage, livestock tanks
Triggers when: Water drops and float falls DOWN
Action: Schedule refill or check supply

Troubleshooting

Receiver won’t connect to WiFi

Ensure you’re using 2.4 GHz (not 5 GHz). Hold button 5-10 seconds for setup mode. Look for “FloatMasterAP” network.

Dashboard shows “Offline” or no data

Verify Receiver has power and green LED. Check internet connection. Transmitter may be out of range — test with units closer together.

Not receiving email alerts

Verify email addresses in dashboard settings. Check spam folder. Add alerts@floatek.ca to contacts. Confirm subscription is active.

Battery draining quickly

Check for obstructions reducing LoRa signal. Cold weather temporarily reduces capacity. Consider adding solar panel ($62).

False alarms triggering

Check float switch wiring and mounting. Ensure floats move freely. Verify correct HIGH/LOW mode selected in dashboard.

Factory reset procedure

Hold button 15+ seconds until LED flashes rapidly. WiFi settings cleared, returns to setup mode.
