Smart outlets & automation

Six independently controlled outlets, how to wire them to your gear, and the rules that make a tank run itself.

22 questions answered.

What is a smart aquarium outlet?

A smart outlet is a power socket you can switch on or off from an app, on a schedule, or in response to a sensor reading. It replaces a wall timer plus a stack of Wi-Fi plugs with a single, integrated controller.

How many outlets does Tank Commander have?

Six independently controlled outlets, all driven by the same controller and accessible from the app, the on-device display, and your automations.

What can I plug into the outlets?

Heaters, return pumps, powerheads, wavemakers, lights, chillers, fans, ATO pumps, UV sterilizers, CO₂ solenoids, dosers, skimmers — anything you’d normally plug into a wall outlet within the per-outlet load rating.

Can I control each outlet individually?

Yes. Every outlet has its own on/off control, friendly name, schedule, and rule — they’re fully independent.

Can I tie an outlet to a sensor reading?

Yes — that’s the core idea. Any outlet can be tied to temperature, pH, TDS, salinity, or leak detection so the device responds to real conditions instead of just a clock.

How do I auto-shut a heater if temperature spikes?

Plug the heater into a smart outlet and add a rule like ‘cut power if temperature is above 80°F.’ It’s the simplest, most effective protection against the most common tank-killer (a stuck-on heater).

How do I run a top-off pump only when salinity drifts?

Tie the ATO outlet to your salinity reading: turn on when salinity is above target, turn off the moment it returns to target. This protects against the classic ATO failure mode of running unchecked.

Can I run a sunrise / sunset light schedule?

Yes. Each outlet supports time-based schedules. For dimmable lights, you’ll typically use the light’s own ramping and just use the outlet to cut power overnight.

Can I switch a chiller on if temperature exceeds a threshold?

Yes. Tie the chiller outlet to temperature with hysteresis (e.g. on above 80°F, off at 78°F) so it doesn’t short-cycle.

Can I create a feeding mode that pauses pumps?

Yes. Set a feed mode that turns specified outlets off for a chosen duration, then turns them back on automatically. Triggered manually from the app or the on-device display.

Can I run a wavemaker on a duty cycle?

Yes — many users prefer their wavemaker’s own controller for fine-grained pattern control, but cycling on/off with an outlet works for simpler setups.

Will the outlets work during a Wi-Fi outage?

Yes. All schedules and parameter-driven rules run locally on the controller. Wi-Fi only matters for app access from outside your home and push notifications.

What load can each outlet handle?

Each outlet is rated for typical aquarium gear (heaters, lights, pumps, fans). Bigger combined loads should be split across the six outlets to keep each well within spec.

Are the outlets surge protected?

Yes — the device includes built-in surge protection so a power-grid spike doesn’t take out your equipment.

Can I override automation manually?

Yes. The app and on-device display always let you flip an outlet on or off, with options for ‘until next schedule event’ or ‘until I switch back to auto.’

Can I see what each outlet is doing in the app?

Yes. The app shows live status, current rule (auto, schedule, manual), and recent activity for every outlet.

Can I label outlets with friendly names?

Yes. ‘Return Pump,’ ‘Heater,’ ‘Reef Light,’ ‘ATO Pump,’ etc. — names show up everywhere from the device display to your phone.

Can I create rules that combine multiple parameters?

Yes. A rule can combine conditions like ‘temperature above 80°F AND lights are on’ for finer control. Most users start simple and grow more sophisticated over time.

Can outlets be triggered by leak detection?

Yes — perhaps the most important rule of all. ‘On leak detected, cut return pump and ATO pump immediately.’ It buys you minutes that prevent floor damage.

Can I use a power outlet for a UV sterilizer schedule?

Yes. Set a schedule for the hours you want it running, or tie it to the lighting schedule.

Will outlets remember their state after a power outage?

Yes — when power returns, outlets restore their last automated state and resume schedules immediately.

Can the device handle 6 outlets running at once?

Yes. Six outlets are designed to be in use simultaneously, within typical aquarium loads.

Tank Commander handles all of this.

Continuous monitoring, smart power outlets, and instant alerts for both marine and freshwater tanks.
