Description

Control has a frequency. The Sentinel Switch is a 433MHz wireless relay controller that puts gates, doors, lighting, and equipment within a button press — no new wiring, no app, no subscription, just a reliable radio link that answers when you call.

Built on the universal 433MHz band, this two-channel receiver accepts commands from matched remote transmitters to switch AC or DC loads across a wide voltage range. Garage doors and gates open to a signal from the car; workshop lights snap on from across the yard; security and convenience equipment activates with a click.

Engineered for easy installation, the relay connects into existing electrical setups and pairs with its transmitter in moments. Forget app-fragile smart systems that need updates and accounts — this is direct, old-school wireless control that works and keeps working.

The 433MHz band is a workhorse precisely because it is simple: a matched transmitter sends a code, the receiver acts, and nothing in between can crash, reboot, or demand a firmware update. That reliability is why gates, garages, and industrial doors still run on it after decades. For anyone tired of smart-home theatrics failing at the worst moment, the Sentinel Switch is the return to control that simply answers.

Some things belong at your fingertip. This is the fingertip for the rest.

Key Features

  • ✦ Universal 433MHz frequency — works with matched RF transmitters and standard 433MHz hardware
  • ✦ 2-channel control — independent switching for two separate loads or zones
  • ✦ Wide voltage range — operates across AC and DC 7-32V and 220V applications
  • ✦ Garage and gate ready — ideal for doors, gates, and access control systems
  • ✦ Easy pairing — connect transmitter and receiver in moments
  • ✦ No app required — direct wireless control without subscriptions or accounts

Application Scenarios

The Sentinel Switch is the quiet upgrade for homes, workshops, and facilities. Automate a garage door, gate, or entrance from your vehicle; trigger worksite lighting while you are hands-full; control pumps, fans, and equipment at a distance; or add a second control point to an existing setup. It shines wherever a physical switch is out of reach or where app-based systems are too fragile for real-world reliability.

Frequently Asked Questions

Q: What can I control with this?

Any AC or DC load within the supported voltage range that a relay can switch — garage doors, gates, lights, pumps, fans, and other equipment.

Q: Does it need Wi-Fi or an app?

No. It operates on the 433MHz radio band with its matched transmitter, so there is nothing to configure, update, or subscribe to.

Q: What voltage does it support?

It handles AC and DC applications across 7-32V and 220V depending on the module variant. Verify your load and select the correct version.

Q: How do I pair the remote?

Pairing connects the transmitter to the receiver using the standard 433MHz learning procedure detailed in the included instructions — typically a short programming sequence.

Q: Is it safe for gate automation?

When installed correctly with the right relay rating for the load, it is suitable for gate and door control. Follow local electrical codes and proper wiring practice.

Q: Can I use multiple remotes?

Many setups accept multiple transmitters on the same receiver, so different family members or vehicles can control the same device.

Q: What is the wireless range?

Range depends on environment and antenna placement, but 433MHz typically reaches tens of meters through open air and works through walls better than higher-frequency systems. Test in your installation to confirm coverage.

Q: How does it handle power interruptions?

The receiver returns to its normal state when power is restored, and a fresh command from the transmitter re-triggers the relay. Keep the power supply matched to the module variant for dependable behavior.

Back to basic reliability

Used to rely on a smart system that kept dropping offline. This relay just answers when you press the button. Recommend it.

Easy install for workshop lights

Flipped my workshop lights to remote control. Programming the transmitter took a minute and range across the yard is solid.

Reliable gate control

Wired this to our driveway gate and the remote works every time from the car. No app, no wifi, just works. Exactly what I wanted.
