Take control in a moment
Set a light or pump to a level yourself whenever you need to, then switch it back to Auto and the normal routine takes over again.

Aquarium control for the hardware you choose
TankGrove runs your aquarium’s lights, pumps, dosing, and sensors from one place. Your equipment connects to small, affordable ESP32 controller boards, and you manage everything from your browser.
No account or hardware needed. Step into a ready-to-use simulated aquarium.

Your readings, routines, and equipment in one overview. View full size
More than a collection of timers: a control centre for your aquarium
See readings, equipment, water-level switches, and feeding modes together. Know what is running, see what needs attention, and make a change without hunting through menus.
Pause things while you feed
Start a timed feeding or maintenance mode with one tap. Your rules decide what pauses, and the normal routine resumes when the timer ends.
Keep your hardware choices
Connect compatible equipment through affordable ESP32 boards. Add more controllers as your setup grows.
Polished control shouldn’t require a proprietary box
TankGrove gives affordable ESP32 boards the kind of app you would expect from a dedicated aquarium controller.

Build the day’s rhythm and see every change
Create a gradual sunrise, a bright afternoon, and a gentle evening. Edit lighting and pump schedules directly on the graph, with a separate curve for each channel, such as white and blue light.
- Drag points or enter exact times and levels.
- Dim a whole schedule at once without redrawing it.
- Try a temporary level without changing the saved schedule.
A routine that knows when to change
Timers are only the beginning. Create visual rules that respond to temperature, water levels, time of day, or the modes you start.
Turn down the lights when the water gets warm. Switch off a pump if the water level drops too low. Pause equipment while you feed. You decide the conditions and what happens.
- Combine conditions and choose different actions.
- Set up a condition once and use it for several pieces of equipment.
- Test rules with pretend readings before you save them.
Everything works together, so there is less to keep track of
The controls, insights, and everyday tools that bring your setup together.
Visual schedules
Shape lighting and pump routines with editable, multi-channel curves.
Automation rules
Make equipment respond to readings, water levels, and time.
Manual control
Adjust equipment instantly, or set a temporary change.
Feeding modes
Pause or adjust equipment together with a timed routine.
Precision dosing
Measure what each pump delivers, plan daily doses, and set a daily maximum.
Supply tracking
Track refills, remaining amounts, and estimated days of supply.
Sensor monitoring
Keep temperature, pH, and water-level readings in view.
History & trends
Look back through sensor readings and equipment changes.
Alerts & notifications
Get the alerts you choose by email, Telegram, or webhook.
Maintenance journal
Keep water changes, tests, cleaning, and reminders together.
Multiple controllers
Spread equipment across several ESP32 boards and control it all in one place.
Browser setup
Set up a new ESP32 over USB, and update its software later from your browser.
What you provide
TankGrove is the software. You provide a supported ESP32 board, your equipment, and any power supplies or driver boards needed to connect it.
What hardware do I need?Your hardware, with a clearer way to use it
- 01
Connect your ESP32
Plug the board into a computer with a USB cable. TankGrove installs its software, connects the board to your Wi-Fi, and adds it to your aquarium. This step needs Chrome or Edge on a computer.
- 02
Add your equipment
Tell TankGrove which pin on the board each light, pump, sensor, or switch is wired to. Name and group everything so the overview makes sense to you.
- 03
Build your routine
Set schedules, add rules, and choose what each light and pump should do if the board goes offline. Check and adjust from your computer or phone.
A dropped connection should have a plan
Wi-Fi and internet outages happen. Each board keeps a copy of its schedules, and you decide in advance whether each light and pump keeps following it or switches to a level you choose.
What keeps working offlineQuestions and answers
What exactly is TankGrove?
TankGrove is aquarium control software for ESP32 boards, which are small, inexpensive Wi-Fi circuit boards that your equipment connects to. It brings schedules, equipment controls, dosing, readings, alerts, and maintenance into one app in your browser. It is not an all-in-one hardware box: you choose and connect compatible equipment yourself.
Can I try it without any hardware?
Yes. The interactive demo opens a simulated aquarium with equipment, readings, and ready-made rules. Change schedules, try controls, and see how device or sensor problems are shown, without switching anything real on or off. No account is needed, and your demo is kept for 48 hours after your last visit.
What hardware do I need?
An Ai-Thinker NodeMCU-32S ESP32 board (currently the supported model), a power supply, and your equipment. Many lights and pumps can’t be plugged straight into the board and need a driver or relay board in between. Setup involves some wiring, so check what each device needs before connecting it. Not sure yet? The demo needs no hardware.
What happens if my Wi-Fi or internet goes down?
Each board keeps a copy of its schedules. If it can’t reach TankGrove for about two minutes, each light and pump does what you chose for it: keep following its schedule, switch to a set level, or stay where it is. Some rules that only use a temperature probe or float switch on the same board keep running too; the Rules page shows which. Until the connection returns, you can’t see readings or change anything from the app, and feeding modes and other rules pause. You can choose to get an alert when a board goes offline.
Can I manage it from my phone?
Yes. The app works in desktop and mobile browsers, so you can check readings, adjust controls, and manage routines from your phone. Setting up a new board is the exception: it needs a computer with Chrome or Edge and a USB cable.
How do I get access to my own aquarium?
TankGrove is still in development, so accounts are invitation-only for now. To be considered for testing, leave your email below; invitations go out a few at a time. Already have an account? Sign in.
What would you automate first?
TankGrove is still in development. Share an idea, follow along, or put your hand up for future testing.
