About the Web Aquarium Pump Remote
Keep your fish happy even when you are away. This remote switches the filter pump, air pump and heater, and shows the water temperature. The feed button pauses the filter for a few minutes so food does not get sucked in.
This remote runs fully in your browser, so it works on any phone or computer with no app to install. Try it now in demo mode. When you are ready, connect it to your own ESP32 or ESP8266 by Bluetooth, Wi-Fi hotspot, home Wi-Fi, USB cable or the internet. We write the Arduino code for you for each option.
How to use it
- Play with the remote in demo mode to see how it works.
- Build your device. See "What you need" below.
- Press Connect my device and pick how you want to connect. Bluetooth or Wi-Fi hotspot are the easiest.
- Press Get the code for this, upload it to your board with Arduino IDE, then connect. Now the buttons control your real device.

Not ready to build? You can still use the remote in demo mode to plan your project and test the buttons.
Commands this remote sends
Over Bluetooth or a USB cable, each command is a short text line like id=value. With MQTT, it goes to your-topic/<id>/set and your device reports back on your-topic/<id>/state. On Wi-Fi, the page calls /<id>?value=… on the device.
| id | Control | Values | Direction |
|---|---|---|---|
pump | Filter pump | ON / OFF | Remote → device |
air | Air pump | ON / OFF | Remote → device |
heater | Heater | ON / OFF | Remote → device |
temp | Water temperature | Device sends a number in °C | Device → remote |
feed | Feed pause (10 min) | PRESS | Remote → device |
Stay safe
Mains electricity (230 V) can kill. If your device switches a fan, light, pump or any appliance, ask a qualified electrician to do the wiring. Use a relay rated well above the load, add a fuse or MCB, and keep everything inside a closed box. For motors and pumps, use a proper starter or contactor. A web remote must never be the only way to switch off a machine.
