Easily Control Your FIRGELLI Linear Actuator Wirelessly with the MHCOZY WiFi Relay
Want to add simple, wireless control to your FIRGELLI linear actuator? In this guide, we’ll show you exactly how to connect a MHCOZY 2-channel WiFi relay to a FIRGELLI actuator, letting you extend and retract it remotely using your smartphone, Alexa, Google Home, or RF remote.
This is one of the easiest ways to bring smart automation to DIY furniture, camper builds, hidden compartments, trap doors, hatches, skylights, or any other project that uses an electric linear actuator.
What You'll Need:
-
✅ 1 FIRGELLI 12V or 24V linear actuator (2-wire)
-
✅ 1 MHCOZY 2-channel WiFi RF relay module (7–32V DC input)
-
✅ A 12V or 24V DC power supply (matching the actuator)
-
✅ Optional: RF remote, Smart Life or Tuya app - download the app with the MHCOZY device
📈 Why Use the MHCOZY WiFi Relay?
The MHCOZY WiFi relay is a compact and affordable smart switch that works with popular smart home apps like Smart Life and Tuya, and can also be controlled via RF remote. It provides:
-
Simple extend/retract switching for 2-wire actuators
-
WiFi + RF remote control in one compact unit
-
Compatibility with Amazon Alexa and Google Home
-
Easy setup and no complex wiring or programming
🔌 Wiring Instructions
1. Connect the Power
-
Connect a 12V or 24V power supply to the input terminals of the MHCOZY relay module. Ensure the voltage matches your actuator's rating.
2. Connect the Actuator
-
Connect the two actuator wires (Motor+ and Motor–) to the normally open (NO) terminals on each relay channel.
-
One relay channel will be used to extend the actuator, the other to retract it. When one relay is triggered, polarity flips and the actuator moves accordingly.
3. Configure the App (Optional)
-
Use the Smart Life or Tuya app to pair with the MHCOZY via WiFi.
-
Assign each relay to a button or trigger.
-
You can now extend or retract your actuator remotely from anywhere.
🎮 How It Works
The MHCOZY relay switches polarity to the actuator when you activate either channel:
-
Relay 1 ON → Extend actuator
-
Relay 2 ON → Retract actuator
Since FIRGELLI actuators reverse direction by switching polarity, the MHCOZY is a perfect fit for simple wireless control.
🛠️ Ideal Use Cases
This setup is great for:
-
Hidden compartments or drop-down shelves
-
Campervan beds or roof vents
-
TV lifts or motorized cabinets
-
Skylight openers
-
Basic trapdoor mechanisms
No need for complex controllers if you're only working with one actuator and need basic movement!
🧠 Want More Features?
While the MHCOZY is perfect for simple control, you may want more advanced functionality like:
-
Adjustable speed
-
Stroke limit control
-
Built-in timer functions
-
Synchronizing up to 4 actuators
-
Support for Hall sensor feedback actuators
- Timer features - If you need the actuators to operate at certain times of the day or on a set frequency basis.
👉 For full actuator control and professional-grade features, pair your MHCOZY relay with the FIRGELLI FCB-2 Controller.

❓ Frequently Asked Questions (FAQ)
Can I use this setup with a 24V actuator instead of 12V?
Yes, the MHCOZY relay supports a wide input voltage range of 7V to 32V DC, so it works perfectly with both 12V and 24V FIRGELLI actuators. Just make sure your power supply matches the actuator voltage.
Does the MHCOZY relay work with Alexa or Google Home?
Yes! The MHCOZY is fully compatible with Smart Life and Tuya apps, which integrate with Amazon Alexa and Google Home. This allows you to trigger actuator movement with voice commands or routines.
Can I control the actuator remotely when I’m not at home?
Yes, once connected through WiFi and the Smart Life app, you can control your actuator from anywhere in the world, as long as your phone has internet access.
What type of actuator works with this setup?
Any 2-wire DC linear actuator from FIRGELLI will work, including Standard, Premium, Track, Bullet, and Mini series. The actuator just needs to reverse direction when polarity is reversed.
Can I control multiple actuators at the same time with this?
Yes, you can wire two or more actuators in parallel, but they will not stay perfectly synchronized without feedback. For perfect multi-actuator sync, we recommend adding the FIRGELLI FCB-2 controller.
How do I add speed control, stroke limits, or synchronization?
For advanced actuator control — including speed adjustments, stroke limits, timed cycles, and synchronizing up to 4 actuators — connect the MHCOZY relay to the FIRGELLI FCB-2 Controller.

Is this setup safe for continuous use?
Yes, but always ensure your power supply is rated for the current draw of your actuator(s), and that relays are not constantly held ON for extended periods, as this may reduce component life.
