How to connect a TV Lift to your Home Automations system such as Control-4, Insteon, Alexa, etc

Integrating a FIRGELLI TV Lift with a Home Automation System

A motorized TV lift becomes much more useful when it behaves like part of the room instead of a separate gadget. In a finished cabinet, bedroom console, kitchen island, conference room credenza, or outdoor entertainment enclosure, the goal is usually simple: one command should raise the TV, power the display, select the correct input, and set the room lighting. A second command should lower the TV and leave the mechanism safely parked inside the furniture.

This guide explains how to connect a FIRGELLI pop-up TV lift, using the TVL-180 style controller shown in the photos, to home automation systems such as Control4, Insteon, Amazon Alexa, Google Home, Crestron, Savant, RTI, URC, Lutron, Home Assistant, SmartThings, Hubitat, and similar platforms. The important point is that the lift does not need to understand each smart home protocol. The automation system only needs to imitate the momentary push of the wired hand controller.

The examples below assume a typical FIRGELLI lift controller with a wired hand pendant that includes three useful control conductors: common, up, and down. Wire colors should always be verified on your own controller before final termination. If your model differs, use the setup documentation for that lift; for model-specific notes see the TVL-180 TV Lift setup guide and the TVL-170 TV Lift setup guide.

Before cutting, soldering, or programming anything, confirm the mechanical installation first. The lift should run smoothly from full down to full up using the factory hand controller. The TV should clear the lid, cabinet opening, cables, wall, and any decorative trim. Automation should be added only after the lift is mechanically reliable, because software cannot fix binding rails, pinched HDMI cables, or a lid that drags on the screen.

How the Three-Wire TV Lift Control Works

The wired controller uses a simple momentary contact method. When the common wire is briefly connected to the up trigger wire, the controller receives an up command. When the common wire is briefly connected to the down trigger wire, the controller receives a down command. The controller then drives the lift until the internal limit switch is reached or another command stops or changes the movement, depending on the controller model and operating state.

For the controller shown in this article, the relevant conductors are typically:

• Beige wire: common reference used by both directions.
• Brown wire: up command input.
• Red wire: down command input.

Think of the automation system as two remote push buttons. One push button briefly connects beige to brown. The other briefly connects beige to red. The automation controller does not need to power the lift motor, reverse motor polarity, or carry motor current. It is only providing a low-current control signal to the existing FIRGELLI controller.

This distinction matters. A common mistake is to connect a smart relay output to the lift power supply or motor leads. Do not do that for this integration. The lift already has a controller designed to handle motor power, limits, and the wired pendant. The automation wiring described here connects only to the command inputs in the pendant circuit.

Choosing the Right Integration Method

Most automation systems fall into one of two practical categories: dry contact closure outputs or voltage outputs. The lift wants a contact closure. If your automation hardware already provides dry contacts, wiring is direct. If it provides a powered output, add relays so the lift sees only an isolated switch closure.

For relay-based control, use two normally open relay contacts: one for up and one for down. The relay coil voltage must match the voltage supplied by your automation output. The contact rating is not demanding because the trigger circuit carries very little current, but choose reliable relays with proper terminals, strain relief, and enclosure protection. If the wiring will live inside a cabinet with AV equipment, avoid loose bare modules; mount the relay board in a low-voltage enclosure or on a DIN rail where it cannot short against metal brackets.

Step-by-Step Wiring Guide

The procedure below shows how to access the pendant wiring and add extension leads for automation. Work with the lift unplugged. Keep the factory hand controller available after the modification; it is useful for commissioning, service, and manual backup. If you are not comfortable opening the controller or soldering small electronics, ask a qualified technician or integrator to perform this part of the work.

Step 1: Open the wired hand controller

Locate the wired hand controller supplied with the lift. Remove the four small Phillips screws from the rear of the plastic housing and separate the two halves carefully. Place the screws in a tray so they do not disappear into the cabinet. Do not pull on the cable while opening the case; the internal conductors are small and are not intended to act as a handle.

Step 2: Remove the internal cover plate

Inside the housing you may see a small cover or retainer above the printed circuit board. Remove it gently. If your controller revision uses clips instead of screws, release the clips rather than prying against the board. The objective is to expose the solder side or conductor entry points without bending the board.

Step 3: Release the cable clamp

The cable harness is normally held by a small clamp. Remove the clamp screws so the cable can move slightly while you inspect the wiring. This prevents strain on the solder joints while you identify conductors and attach the new leads.

Step 4: Expose the PCB and identify the command wires

Handle the board by its edges and avoid touching component leads more than necessary. Identify the beige, brown, and red conductors before making any connection. If lighting is poor, use a magnifier and take a photo before you start. Photos are helpful later if you need to confirm the original routing.

The beige common wire needs to be available to both automation channels. In many installations the cleanest approach is to run one common conductor from the pendant to a small terminal block, then jumper that common to the common side of the up relay and the down relay. This makes the wiring easier to service than twisting several wires together inside the controller housing.

Step 5: Add extension wires

Use three small-gauge stranded control wires long enough to reach your automation module or a nearby junction point. For typical cabinet runs, 20 AWG to 22 AWG stranded wire is practical because it is flexible and mechanically stronger than very fine signal wire. Label both ends as common, up, and down. Do not rely only on color once the wires disappear behind AV equipment.

If you solder to the PCB, use rosin-core electronics solder, a clean iron tip, and the minimum heat needed for a bright joint. Avoid acid-core solder. Avoid leaving long exposed strands that could bridge adjacent pads. Add heat-shrink tubing or insulation where needed, and provide strain relief so movement of the external cable is not transferred directly to the solder joint.

An alternative is to splice into the controller cable a few inches from the pendant, where there is more room to work. If you choose this method, open the outer jacket carefully, identify the same three conductors, and make soldered or crimped splices with proper insulation. This method can be easier for installers who prefer field wiring over PCB soldering, but it still requires careful strain relief.

Step 6: Bench-test the added wires before final assembly

Before closing the housing, plug the controller back into the lift control box and connect power only when the mechanism is clear. Briefly touch the common wire to the up wire. The lift should start moving upward. Briefly touch common to down. The lift should move downward. Use short taps, not a permanent jumper. If up and down are reversed, swap the labels or relay assignments for the brown and red conductors.

During this test, listen for normal motor sound and watch for cable movement. If the lift hesitates, chatters, or behaves differently from the factory hand controller, disconnect power and inspect your new connections before continuing.

Step 7: Reassemble and protect the wiring

Route the new control cable through a suitable opening so it is not pinched by the housing. Reinstall the cable clamp, internal cover, and housing screws. Tighten screws enough to secure the plastic, but do not strip the posts. At the automation end, land the three wires on a terminal strip or relay module so future service does not require opening the pendant again.

Connecting to Popular Home Automation Platforms

Control4

Control4 installations commonly use relay modules or contact outputs programmed in Composer. Use two relay channels: one for up and one for down. Wire the lift common to the common side of both channels, then wire the up and down trigger wires to the normally open side of their respective channels. Program the relay action as a momentary pulse. An example pulse duration is 0.5 seconds; if your system misses commands, increase slightly after confirming the relay is working.

A useful Control4 scene might be named Movie Mode. The sequence can lower shades, set lighting, power the AVR, select the streaming input, and then pulse the up relay for the lift. A shutdown scene can pulse the down relay only after the display has powered off and any lid or cable path is clear.

Insteon

Insteon integrations usually need relay-capable I/O modules. Assign one output to raise and one output to lower. Configure the outputs as momentary rather than toggle. Toggle mode is a common mistake because it can leave a relay energized when only a quick pulse is required. If a module has only one relay, use two modules or choose a dual-output device suitable for isolated contact closure.

Alexa and Google Home

Voice assistants normally do not provide a bare relay output by themselves. They need an intermediary such as a compatible smart relay, SmartThings hub, Hubitat hub, Home Assistant controller, or Wi-Fi relay module. Use two relay channels and give them clear names such as TV Lift Up and TV Lift Down. Then create routines with natural phrases. For example, Alexa, raise the TV can pulse the up relay, while Alexa, hide the TV can pulse the down relay.

For voice control, avoid ambiguous phrases such as turn on TV lift if the same room also has a television named TV. A clear naming convention prevents the assistant from powering the display when you intended to move the lift. For a more complete example of smart lift sequencing, see the FIRGELLI guide to a motorized TV lift with smart home integration.

Crestron and Savant

Crestron and Savant systems are well suited to this type of integration because they offer programmable I/O, conditional logic, and strong scene control. Use isolated relay outputs from a processor, I/O expander, or DIN rail module. Program each output as a pulse, not as a maintained state. Professional programmers can add safeguards such as blocking a down command while a cabinet service mode is enabled or preventing operation when an occupancy sensor detects someone near the lift opening.

Home Assistant, Hubitat, SmartThings, and custom controllers

DIY hubs work well when paired with reliable relay hardware. In Home Assistant, a template button or script can energize a relay channel for a defined time and then turn it off. In Hubitat or SmartThings, use routines or rules to create the same momentary action. If you are using an Arduino or ESP32, isolate the microcontroller from the lift inputs with relay contacts or a proper opto-isolated interface. FIRGELLI also has related smart home actuator guidance in the smart home window actuator integration guide, which is useful if your project includes other automated motion in the same room.

Programming, Timing, and Safety Checks

Start with the simplest working command: pulse up, pulse down. Do not build complex scenes until those two commands are reliable. A practical commissioning sequence is:

1. Run the lift with the factory hand controller through a complete up and down cycle.
2. Run the lift with temporary jumper tests at the new control wires.
3. Run the lift from the relay module using local test buttons or software controls.
4. Run the lift from the automation scene.
5. Run the full room sequence, including display power, audio, lighting, and lift movement.

Most systems work with a short pulse. As an example assumption, 0.5 seconds is a reasonable starting point for many relay modules. If the controller does not respond consistently, increase the pulse to 0.75 or 1.0 seconds. Do not use a long maintained relay output unless your controller documentation specifically requires it. The goal is to imitate a button press, not hold the button down for the entire lift travel.

Use interlocks where the installation warrants them. In a cabinet with a hinged lid, confirm the lid opens freely before the lift rises. In a bedroom or child-accessible space, keep the manual controller accessible and do not create automatic schedules that move the TV when nobody is watching the mechanism. For an outdoor cabinet, add extra checks for moisture protection and cable strain; the outdoor TV lift cabinet guide covers weatherproofing considerations that affect the entire installation.

If you need position feedback, the basic three-wire control method does not report height back to the automation system. You can approximate positions with timed movements, but timed presets drift if the lift starts from an unexpected position. For projects that require verified position, add external limit switches, reed switches, optical sensors, or a controller designed for feedback. Control theory concepts such as response error and closed-loop behavior are covered in FIRGELLI resources like the steady-state error calculator and root locus calculator, although a standard TV lift installation normally remains a simple open-loop scene device.

Troubleshooting Common Integration Issues

The lift works with the hand controller but not automation

• Confirm the automation output is actually changing state when commanded.
• If using dry contacts, verify continuity across the relay contact with a multimeter during the pulse.
• If using voltage outputs, verify the voltage matches the relay coil rating.
• Check that the relay contact is wired to normally open, not normally closed.
• Confirm the beige common wire is shared with both up and down relay channels.

The lift moves the wrong direction

The up and down trigger wires are swapped at the relay or terminal block. Swap the up and down connections. Leave the common wire in place.

The lift responds only sometimes

• Increase the pulse duration slightly.
• Inspect solder joints and crimp connections for looseness.
• Move low-voltage control wiring away from AC mains cables and large power supplies.
• Check that the TV lift power supply remains stable while the motor starts.
• Confirm the automation hub is not sending duplicate or conflicting commands.

The controller stopped working after modification

Disconnect power and inspect the pendant carefully. Look for solder bridges, stray wire strands, pinched conductors, or a cable clamp pressing on the new leads. Recheck the photos you took before modification. If the issue is not obvious, remove the automation wiring and restore the controller to its original state before further troubleshooting.

The TV starts moving during unrelated voice commands

Rename the relay devices and routines. Avoid device names such as TV, lift, or switch if those names overlap with other smart home devices. Use explicit scene names such as Raise Hidden TV or Lower Cabinet TV. Also confirm that the relay device is set to momentary operation so it cannot remain on after a cloud or hub delay.

Professional Installation Notes

For integrators, the difference between a working demo and a serviceable installation is documentation. Label the pendant end, relay end, power supply, and automation outputs. Leave a wiring diagram in the rack or cabinet. Photograph the pendant wiring before closing it. Note the programmed pulse duration, relay channel numbers, hub device names, and any safety logic.

Route control wiring separately from AC wiring where practical. Use grommets when passing through cabinet panels. Leave a service loop at the controller and at the relay enclosure so the TV lift can be removed without cutting wires. If the lift is inside custom cabinetry, make sure the cabinet builder provides an access panel for the controller, power supply, and automation relay. A beautiful cabinet that cannot be serviced becomes expensive the first time a connector needs to be checked.

Finally, train the user. Show the homeowner or facility manager how to operate the system from the automation interface and from the factory hand controller. Explain what normal operation sounds like, where the manual control is stored, and when to stop using the lift and call for service. The best integration is not only impressive on day one; it is understandable two years later.

Bringing It All Together

A FIRGELLI TV lift can be integrated with almost any smart home system because the control requirement is simple: momentarily connect common to up, or common to down. Professional platforms usually provide dry contact outputs directly. Consumer and DIY platforms can do the same through smart relays or hub-compatible relay modules. Once wired correctly, the lift can become part of scenes that manage lighting, audio, shades, and display power.

The most important engineering checks are straightforward. Verify the mechanical lift first. Keep motor power separate from command wiring. Use momentary relay outputs. Label every conductor. Test each stage before adding the next layer of automation. If your project is still in the planning stage, you may also find the FIRGELLI overview of why homeowners use TV lifts helpful for choosing the best room layout and cabinet approach.

Frequently Asked Questions

Will this method work with Control4, Insteon, Alexa, Google Home, Crestron, and Savant?

Yes, provided the system can create a momentary dry contact closure or can drive a relay that creates one. The lift is not communicating over the smart home protocol directly; the automation system is simply imitating the wired controller button press.

Do I need two relays or one?

You need two independently controlled normally open contacts: one for up and one for down. That can be two separate relays or one dual-channel relay module. Do not wire both directions to the same relay.

Can I keep using the original hand controller?

Yes. The hand controller should remain functional if the added wires are connected correctly and do not interfere with the original circuit. Keeping the hand controller available is recommended for service and backup operation.

What pulse duration should I use?

As an example assumption, start around 0.5 seconds for many relay-based systems. If the lift does not respond reliably, increase the pulse slightly. The correct value depends on the controller and relay hardware, so verify by testing.

Can I set exact height presets?

The basic three-wire method gives up and down commands, not measured position feedback. Timed presets can work for simple scenes, but they are not the same as verified position control. If exact position is required, add appropriate sensors or use a feedback-based motion system.

Is soldering required?

Not always. Soldering to the controller PCB is one method. Splicing into the correct conductors in the pendant cable is another. Both require careful identification, insulation, and strain relief. If you are unsure, use a qualified technician.

What is the biggest mistake to avoid?

Do not apply motor power or automation voltage directly to the lift command wires. The command wires need an isolated contact closure. If your automation output is powered, use a relay to isolate it from the TV lift controller.
