Why Aren't My SwitchBot Hub 2 Blind Commands Reaching the Curtain Motor?
- Hub 2 placed too far from curtain motor exceeding Bluetooth relay range
- Curtain not paired to Hub 2 and only connected via direct Bluetooth
- Hub 2 firmware or curtain firmware out of date for hub relay support
Problem Description
Your SwitchBot Hub 2 is not delivering open and close commands to your SwitchBot Curtain motor. The SwitchBot app shows the command as sent but the curtain does not move. Direct Bluetooth control from your phone works when you are near the motor but Hub 2 commands from across the house fail. This is caused by the Hub 2 being too far from the Curtain motor to reach it with its IR or Bluetooth relay, or the Curtain not being fully paired to the hub.
Symptoms
- SwitchBot app sends curtain command but motor does not move
- Curtain works via Bluetooth when phone is nearby but Hub 2 commands fail
- Automations through Hub 2 complete successfully but curtain ignores them
- Hub 2 shows curtain as online but commands time out intermittently
- Direct manual control on motor works but app control via hub does not
- Command delivery works sometimes but fails randomly throughout the day
Recognize these? Here's what usually causes it.
Common Causes
- Hub 2 placed too far from curtain motor exceeding Bluetooth relay range
- Curtain not paired to Hub 2 and only connected via direct Bluetooth
- Hub 2 firmware or curtain firmware out of date for hub relay support
- Hub 2 WiFi connection intermittent causing command delivery failure
- Curtain motor battery below 20 percent causing it to skip hub commands
- Multiple Hub 2 units creating command conflicts for the same curtain
Most fixes happen in the first 3 steps.
Do not pair one Curtain motor to two different Hub 2 units. Dual hub pairing causes command race conditions where both hubs attempt to control the motor simultaneously resulting in unpredictable behavior.

Step-by-Step Solution
Pair Curtain to Hub 2 Properly
Bluetooth SwitchBot devices only relay through the Hub 2 when they are paired to that specific hub. Open the SwitchBot app and tap the Curtain device then go to Settings and look for Hub Device. Confirm Hub 2 is selected as the home hub for this curtain. If no hub is listed the curtain is operating in Bluetooth-only mode and only your phone can control it directly. Tap Hub Device and select your Hub 2 to enable remote and automation control through the hub.
Move Hub 2 Closer to Curtain
SwitchBot Hub 2 relays commands to curtain motors via Bluetooth with a maximum range of approximately 10 metres in open air. Walls reduce this to 5 to 7 metres. If the hub is in a different room or on a different floor from the curtain motor the relay signal may not reach. Move the Hub 2 to the same room as the curtain or to an adjacent room with a clear path. After moving the hub test curtain commands from the app.
Check Hub 2 WiFi Connection
The Hub 2 must have a stable WiFi connection to receive commands from the SwitchBot cloud when you control the curtain remotely. In the SwitchBot app go to Hub 2 settings and check the WiFi signal indicator. If the hub shows a weak WiFi connection or offline status it cannot receive commands even if its Bluetooth relay to the curtain is working. Improve WiFi signal at the hub location or move it to a better-connected position.
Update Hub 2 and Curtain Firmware
Open SwitchBot app, go to Hub 2 settings then Firmware and update to the latest version. Also go to the Curtain device settings and check for a firmware update. Hub-to-device Bluetooth relay protocols are updated regularly and a mismatch between Hub 2 firmware and Curtain firmware can cause commands to be rejected silently. After both updates power cycle the Hub 2 by unplugging it for 10 seconds before testing curtain control.
Charge Curtain Battery
SwitchBot Curtain 3 motors reduce Bluetooth reception sensitivity when the battery falls below 20 percent to extend remaining runtime. At low battery the curtain may receive some commands but ignore hub-relayed ones that have lower signal strength than direct phone Bluetooth. Charge the Curtain motor via USB until the battery indicator in the SwitchBot app shows 80 percent or above then retest hub commands.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If the hub reconnects then drops every few minutes, check for an IP conflict — two devices sharing the same DHCP address fight each other continuously.
Use the SwitchBot scene feature to create morning and evening curtain automations through Hub 2. Hub-based automations run without your phone being present making them more reliable than phone-triggered shortcuts. **Product Intelligence:** - Hub 2 required for Matter - Hub Mini for basic Bluetooth/IR - Battery devices use CR2 or AAA
Hub disconnections that cycle repeatedly are almost always IP conflicts — two devices fighting over the same DHCP lease after a router restart.
- Hub 2 placed too far from curtain motor exceeding
- Curtain not paired to Hub 2 and only connected
- Hub 2 firmware or curtain firmware out of date
- Hub 2 WiFi connection intermittent causing command delivery failure
- Curtain motor battery below 20 percent
