Control Freak Grow, brought to you by Control Freak

Sound familiar?

You should be sleeping. So should the worry.

The heater stuck on all night.

Set a temperature limit. Above it, the heater outlet turns off, exhaust turns on and you get an alert. It cannot prove a relay inside your gear is really off.

The Wi-Fi went off line overnight.

The rules keep running on the controller. A power outage messed up the timers? When power returns, it picks up where it left off.

The smart plug missed the light cycle.

Lights use the controller clock. Keep the light cycle with the rest of the grow, instead of another Wi-Fi plug and another app.

How it works

Your gear. One set of rules.

  1. 01

    Connect the gear you own

    Plug lights, fans, a heater and humidity equipment into the Power Hub. Use gear that turns on when plugged in.

  2. 02

    Set your grow stage

    Choose Seedling, Growing, Lights off or Away. Set temperature and humidity targets, light times and your temperature limit.

  3. 03

    Let the controller keep watch

    Two probes compare readings. Rules run here, and alerts reach you by push, text, email or alarm.

What makes it different

Several brands. Fewer nightly chores.

Woke up to everything soaked?

Humidity has a target, with VPD alongside it. A high humidity alert tells you to check the grow. It does not detect or stop a water leak.

Humidity won't budge.

Minimum run times let the dehumidifier work without being flicked on and off. Check its capacity, bucket and drainage too.

Several brands and several apps.

Keep any brand of equipment that starts when plugged in. Eight switched outlets bring its on and off rules together.

What's included

One kit. Tent or greenhouse.

8switched outlets
  • Controller with Home Assistant built in
  • Power Hub with 8 switched outlets
  • Temperature and humidity sensors, with two probes to compare readings
  • Controller clock schedules and grow stage rules

Lights, fans, heater, humidifier, dehumidifier and heat mat are your own equipment. Check that each turns on when plugged in.

Home Assistant

Your grow, on your home network.

Want it in Home Assistant without a vendor cloud? Home Assistant is built in, with grow readings and controls together on your network.

The rules stay on the controller

Temperature limits and schedules keep running even when Wi-Fi drops. No subscription. Phone alerts need internet; a local alarm needs connected alarm equipment.

Honest limits

Know what it does before you plug in.

Switching, not fan speed

It switches gear on and off. It does not set the speed of other brands’ fans. “Exhaust full” means its outlet is on; the fan runs at the speed you set on the fan.

Power still matters

Nothing runs in a power cut. After power returns, the controller resumes. Phone alerts during an outage need a small UPS on the controller and router, plus working internet.

An off command is not proof

It cannot prove a relay inside other gear is really off. It is not fire protection. It does not control odor.

Readings need a check too

Two probes give a disagreement alert. Check sensor placement, equipment and the grow when an alert arrives.

Try it here

Take the night shift for a minute.

Change stages, switch outlets and try the faults owners worry about. All readings are simulated.
