Start with the remote LED. Press Up, Down or My. If it does not light, replace the remote’s CR2430 coin cell. If the LED works, check motor power, then pairing and control-protocol settings. Battery shades can usually be checked safely at home; wired motors, inaccessible reset controls and repeated faults should go to the installing dealer or Somfy support.
Identify the fault before resetting anything
Somfy systems may use RTS, io-homecontrol or Zigbee controls. Button sequences differ by motor generation and protocol. A factory reset or re-pairing can remove remote associations, groups and travel limits, so first record the motor label, remote model and whether the shade is battery-powered, plug-in or in-wall.

- No remote LED: start with the CR2430 battery.
- LED works but the shade is silent: check battery-wand contacts or escalate a wired installation.
- Shade moves from the remote but not the app: troubleshoot TaHoma pairing and radio range.
- Shade stopped after a reset or new remote: restore the correct protocol pairing and limits rather than repeating random resets.
1. Check the remote and its battery
- Press Up, Down or My and watch the indicator.
- If the LED does not illuminate, replace the CR2430 coin cell. Refit the cover and test again.
- If the LED illuminates but no motor responds, continue to the power and pairing checks below.
Use a battery specified for the remote model and keep the coin cell away from children and pets. A replacement transmitter must match the motor’s protocol and model; a visually similar Somfy remote is not automatically compatible.
2. Verify motor power
Battery-powered shades
- Confirm the battery wand is fully plugged into the motor lead.
- Check that the batteries touch the spring contacts and are installed in the correct orientation.
- Make sure both battery-wand end caps are tight.
- Replace depleted batteries, then test the shade with the working remote.
A loose connector or end cap can make a healthy motor appear dead. Do not force a connector or dismantle the motor head.

3. Re-pair a Somfy remote
The exact procedure depends on the motor and remote, but Somfy’s standard programming sequence uses the remote’s recessed programming control. A paperclip or similar blunt tool may be required.

- Stand close to the shade and identify the remote’s PROG button.
- Press and hold the PROG button until the window covering gives a short jog (a brief movement up and down).
- Test Up, Down and My.
If there is no jog, locate the motor’s reset pinhole. Trigger one jog with the reset control, then press and hold the remote PROG button until the shade jogs again. Test the transmitter once more. If the pinhole cannot be found or the shade still does not respond, stop and contact Somfy customer service or the installer rather than guessing at a reset sequence.
4. Reset TaHoma motorisation safely
Somfy’s TaHoma procedure must be performed with the individual control point assigned to that motor, not from a different group control.

- EASY INSTALL BLINDS: The remote blinds have a simple and practical no-drill mechanism(suitable for inside mount). Attach the adhesive extension block to the groove of the upper rail (it is forbidden to put more than one block), and then push it into the window frame. There is a battery compartment at the top to supply power for the shades. If the batteries are low, just take them out and replace. A stylish valance is included to block the light from the gap between fabric and the top rail
- EXCELLENT SHADING EFFECT: The fabric is made of a three-layer blackout textured fabric, which is safe and durable. It is a great combination of UV and privacy protection,suitable for bedrooms, living rooms, kitchens and office areas, etc
- SMART IMPLEMENTATION: The AX290 motor requires a smart bridge for APP control/voice control, which requires a hub at home, and you may try our hub. All models of Alexa and Google Assistant can be used to control motorized window shades, and can set timers and other scenes
- CONVENIENT LIFESTYLE: Motorized blinds allow you to achieve a smart home at minimal cost. In the morning, when you are still asleep, the shades in the bedroom open automatically on time, and the warm sunlight spread into the room lightly to wake you up for a new day, and in the evening, when the sun sets, the shades fall on time, creating a private space for the family
- SERVICE: We focus on products and service, if the fabric or components are damaged in any way when you receive the items, please take a photo and send it to us within 60 days, we will replace. Hapadif provides 2-year warranty for motors and controllers
- Use the individual control point and hold the relevant Up or Down control until the motor moves.
- Press and hold that control point’s PROG button until the motor moves up and down twice.
- Rebuild the required remote, group and TaHoma associations and check the travel limits.
This operation resets the motorisation to its original configuration. Treat it as a last resort when preserving existing programming matters.

App failures are not always internet failures. The motor protocol, pairing order and distance from the TaHoma hub can prevent a successful connection.

Remote reset in supported systems
Somfy’s support guidance for certain systems resets a remote by holding PROG until its LED flashes red three times. This is model-specific; confirm the instruction for your remote before using it.

For systems covered by Somfy’s Zigbee guidance, five presses on the motor head can start Bluetooth pairing mode. Ten presses, or holding the control until two jogs, can place the motor in Zigbee pairing mode for a TaHoma switch. These counts are not universal across all Somfy motors, so use them only when the motor documentation identifies the same procedure.
Complete the app setup
- Place the TaHoma switch close enough to the motor for reliable radio communication.
- Follow the app’s discovery order; pairing the hub before the motor is ready can time out.
- After discovery, test a single shade before recreating scenes or groups.
- If the remote works locally but TaHoma does not, repeat protocol-specific pairing rather than replacing batteries unnecessarily.
Choose the right remedy
| Situation | DIY action | When to replace or call | Risk to existing settings |
|---|---|---|---|
| Remote LED is dark | Install a CR2430 battery and retest. | Replace the remote if the LED remains dark with a new cell. | Normally none. |
| Battery shade has no movement | Reconnect the wand, check spring contacts and tighten end caps; replace depleted batteries. | Call the installer for persistent failure or physical damage. | Normally none. |
| Remote is lost or defective | Buy a model- and protocol-compatible Somfy shade remote control, then pair it. | Use an installer if the motor label or protocol is unknown. | Pairing may alter which transmitters control the shade. |
| TaHoma cannot find a motor | Use the documented Bluetooth or Zigbee pairing sequence and improve radio range. | Escalate after a protocol-confirmed retry fails. | New pairing can remove old app associations. |
| Wired motor is dead | Do not open mains wiring. | Contact the installing dealer or qualified service provider. | Professional diagnosis avoids an unnecessary factory reset. |
| Reset pinhole is inaccessible | Do not pry open the motor head or blind. | Contact Somfy support or the installer. | Limits and associations remain protected. |
After a successful fix
- Run the shade through a full up-and-down test.
- Confirm the My (favorite) position and both travel limits.
- Check every intended remote, group and TaHoma scene individually.
- Label the motor protocol and keep the programming instructions with the installation record.
When professional help is the safest option
Stop DIY work if the motor is wired, the blind is damaged or obstructed, the reset control cannot be reached, or several protocol-correct pairing attempts fail. Provide the installer with the motor label, remote model, power type, LED behavior and the last step that produced a jog. That information avoids an unnecessary loss of limits or groups.
