    Hello, I would like to present an idea for a quick installation of a remote control window blind control. The control itself and the motor bought as ready-made components. Everything is visible in the pictures. Time to open the roller shutter on a large window about 5 seconds. The remote control works in several modes, but I chose this one: pressing the first button causes the roller shutter to close, releasing it stops it. The second button (same principle) opens the roller shutter. The motor and control were bought at a foreign auction. The advantage of this solution is that the original mechanism is not interfered with and in case of power failure you can always disconnect the ball chain from the motor and open it manually. The whole cost is about 110 PLN plus one hour of work

    The gear works quite quietly even at night. The link may come in handy as this auction only comes with a threaded sleeve to which the white plastic pinion is attached and a piece - an angle bracket - that fixes the motor to the window.

    The cogs inside are metal. And the speed? Judge for yourself.

    The opening time is not adjustable. You can order a motor with 38rpm then it will be slower. There are no limit switches. As I described in the first post, the motor is switched on by pressing a button and off by releasing it. It is a simple mechanism.

    Hello again. I have extended the roller shutter control with another controller. For two motors, both controlled separately from one remote control or from the phone via WiFi. And it turned out that the new controller, in addition to several others, has a timer programming function, so the limiters are not needed because you determine how many seconds the roller shutter opens or closes and program it with an accuracy of 0.5 seconds. The operating software is eWeLink for Android.

    Everything is correct if we write always about full opening and closing, but what if we stop in the middle?
    As you can see, however, position sensors are needed.

    Regards.

    You can quietly close to the home position with one of the buttons.

Topic summary

✨ A user proposed a simple installation method for remote control of roller shutters using ready-made components, allowing for quick operation (approximately 5 seconds to open). The system utilizes a motor and remote control purchased from foreign auctions, maintaining the original mechanism for manual operation during power failures. The remote features two buttons for opening and closing the shutter, with the motor's speed set at 92 RPM. Discussions highlighted concerns about the lack of limit switches and safety features, which could affect automation reliability. An update revealed an extension of the system with a new controller that includes timer programming, allowing for precise control of opening and closing times, and the ability to control multiple motors from a single remote or via WiFi using the eWeLink app.

FAQ

TL;DR: DIY bead‑chain blind motor opens a large window in about 5 seconds, and “the original mechanism is not interfered with.” Budget ≈110 PLN, about 1 hour install, hold‑to‑run remote, and manual override. [Elektroda, aleks-1967, post #18240736]

Why it matters: For renters and DIYers who want quick, non‑invasive remote or Wi‑Fi control of roller blinds without rewiring.

Quick Facts

How can I motorize a bead‑chain roller blind without modifying it?

Use a ready‑made chain‑drive motor with a hold‑to‑run RF remote. It opens a large window in about 5 seconds. The build leaves the original mechanism untouched and allows manual use by disconnecting the chain. Expect ~110 PLN cost and about one hour of work. [Elektroda, aleks-1967, post #18240736]

How does the handheld remote operate in this setup?

Button 1 closes while pressed; releasing it stops movement. Button 2 opens under the same hold‑to‑run logic. The remote supports several modes, but the author chose this safety‑friendly, press‑and‑hold behavior. [Elektroda, aleks-1967, post #18240736]

Which model numbers appear in the photos?

The controller label shows “KC323.” The string “CHW4632-370” was noted but could not be found again among listings. This helps when searching replacements after links expire. [Elektroda, Anonymous, post #18242162]

Are the gearbox gears metal or plastic?

They are metal. As the author confirmed, “The cogs inside are metal.” This improves durability under frequent starts and stops. [Elektroda, aleks-1967, post #18242222]

How loud is the drive?

The gearbox runs quietly, even at night. As reported by the builder, “The gear works quite quietly even at night.” Mounting to a solid surface further reduces vibration. [Elektroda, aleks-1967, post #18242193]

Does the basic controller have limit switches or auto‑stop?

No. Opening time is not adjustable on the basic RF unit, and there are no limit switches. It runs only while you press the button. “It is a simple mechanism.” [Elektroda, aleks-1967, post #18242247]

Is the default speed too fast, and how can I slow it down?

If you want slower travel, choose a motor specified at 38 rpm instead of the faster unit. This change lengthens travel time and widens timing margins for automation. [Elektroda, aleks-1967, post #18242247]

What RPM is shown in the example build?

The example photo shows a 92 rpm motor. That speed produced about a 5‑second full open on a large window in the build. [Elektroda, Anonymous, post #18243661]

Is this build suitable for full home automation and unattended runs?

Not in its basic RF form. “Since there are no timings and no limiters or other safety features then in this form it is not very suitable for automation.” Use a smarter controller if you need unattended operation. [Elektroda, Anonymous, post #18242252]

How do I add Wi‑Fi timer control?

Install a Wi‑Fi controller that works with eWeLink.
  1. Wire the controller and pair it with the eWeLink app.
  2. Assign each output to a motor channel.
  3. Program open/close durations with 0.5‑second resolution per direction. This adds phone control and scheduled movement. [Elektroda, aleks-1967, post #18316147]

How accurate are the timers—can they replace limit switches?

The Wi‑Fi controller lets you program open and close durations with 0.5‑second resolution. The author notes that “the limiters are not needed” when you time full travel. Use this for full open/close runs, not position tracking. [Elektroda, aleks-1967, post #18316147]

Can one remote or phone control two blinds independently?

Yes. The updated controller runs two motors, each controlled separately from one remote or from your phone over Wi‑Fi via eWeLink. This supports independent channels. [Elektroda, aleks-1967, post #18316147]

What about partial positions and mid‑travel stops?

Timers cover full opening and closing. If you stop mid‑travel and want repeatable positions, you need position sensing. As stated, “position sensors are needed.” Consider encoders or end‑stop sensors for accurate scenes. [Elektroda, bhtom, post #18316283]

What happens during a power outage?

You can disconnect the bead chain from the motor and operate the blind manually. This non‑invasive design preserves full manual functionality during outages. [Elektroda, aleks-1967, post #18240736]

How do I return to a known position after stopping mid‑way?

You can drive the blind back to a reference end stop manually. As noted, “You can quietly close to the home position with one of the buttons.” Then resume timed operation. [Elektroda, aleks-1967, post #18316284]
