How many apps do you have to open to control your smart products?
Home Assistant comes pre-installed with the Control Freak integration, so the tank and the rest of the home land in one place — and you can simplify to a single app. Multi-platform integration built in: ask Alexa what the status is, tell Google to adjust the temperature, and receive automated voice alerts to let you know when something is out of balance. Home Assistant itself stays on your home network.
Built for sump-tank reef keepers.
Reliable control and alerts without wiring a DIY board or juggling a stack of vendor apps. For hands-on keepers who run — or want — Home Assistant, and care that pumps and heaters keep doing the right thing when Wi-Fi or an app hiccups.
What makes it different
Keeps working when the internet doesn’t
The box under the stand runs the tank. Ethernet, Wi-Fi, and its own Wi-Fi fallback.
Home Assistant pre-installed
Control Freak integration already set up. One hub for tank and home. Ask Alexa what the status is, tell Google to adjust the temperature, and get voice alerts when something is out of balance.
Auto water leveling + leak alarm in the kit
Tops up evaporation with overfill lockout, plus a floor leak sensor. Just add a reservoir.
Pumps keep running if the controller loses power
Return and powerheads stay on. The heater turns off and falls back to its own thermostat.
Heater cutoff
Probes watch the tank and switch the heater off above your limit.
Set up in minutes
Scan a QR code. Keyed, colour-coded plugs only go where they belong.
In perfect balance
Continuous dosing from a three-head doser for calcium, alkalinity and magnesium, with pH right on the home screen.
What’s in Reef Control Pro
- Controller with Home Assistant + Control Freak integration
- Power Hub — 8 outlets
- Two temperature probes (room for more)
- Auto top-off pump + level sensors (you add the reservoir)

- pH probe
Room to grow
Planned optional extras may include ORP and salinity probes, extra temperature probes, an extra Power Hub, and a reservoir.
To be clear about what it isn’t: no subscription, no automatic water changes, no automatic chemistry adjustments from probe readings, no LED-brand dimming protocols, and up to 8 outlets per controller.
Try the home screen
All calm in the reef. Toggle the 8 smart outlets, start Feed or Maintenance to pause the pumps, tap a dosing head for the next dose, try a leak or high-temp “what if”, or preview a sample alert.
This is a marketing simulation with example data — not live hardware and not the real app. No login, no cloud.

We’re looking for reef keepers to test Reef Control Pro on their own tanks before launch.
