Review: Solid option to automate your curtains - I bought these on a whim during Prime week. They arrived really quickly, as usual for desertcart and I started setting them up straight away. It's probably me, but I didn't realise that I needed two units, as my curtains open out from the centre to the sides. Whoops! Ordered another one and it also arrived quickly. Once I got over that minor hurdle, I started setup. I like that there's a choice between either a video setup guide or a set of images, so tried the video and it was straightforward and easy to follow - until I noticed that I was setting them up backwards - went back a few steps and rectified the problem. It looks much better set up correctly *behind* the curtains... Again, user error here :-) So now that they're installed, the calibration was quick - I adjusted the magnets a few times to get the curtains to close as much as possible. Looks like I'll still need to close them manually the last tiny bit at the bottom, but I really bought them for opening the curtains in the morning, to help me wake up more naturally, so this isn't a deal breaker. They work perfectly, and are intuitative to use. My curtains are heavy and it's strong enought to pull them without any issues. The units themselves are very solidly built, and grip the curtain pole really well. I've messed about with them quite a bit and the battery level hasn't budged - I also really like that they're USB C. I use plenty of Switchbot products, so am familiar with the app already, and I can fit them into other automated routines I have. I'm just waiting on my projector to arrive so I can have a mini movie night in bed, with the lights fading down, the curtains closing and the projector switching on! So far, I'm pretty happy with everything, and although they're not cheap, they feel like they're going to last a long time due to the build quality. Can recommend!
Review: Go to Device for Curtain Automation - Quality item, brilliantly packaged with everything needed to turn Ring Top, Grommet, Tab Top or Back Tab into smart curtains. Beads fixers are supplied for Grommet curtains, clips for Tab Top / Back Tab curtains. It is worthwhile to take time to look through the pictorial guide or watch the video. Many different options to control smart actions, from simply pulling curtain >5cm to activate action, Switchbot remote (not supplied), voice activation (hub needed) or app (hub needed). For my installation I have a grommet curtain, so I needed beads fixers (to aid opening and give a uniform look). Absolutely no problem with attaching them (maybe a bit stiff to open) or adjusting length of beads. Fixing the Main Unit and Hook (Rod) took 30 seconds. Fitted magnet and then just ran through calibration in the app. I can now control curtain open/close using Alexa (think Google Assistant can do %age, but I haven't tested). Through the app I have scheduled opening times, and using automation options curtain closes at sunset. In both cases you have the Motion Mode option of standard, Silent or QuietDrift. The QuietDrift is snail's pace, but virtually silent. In my setup I can still hear Silent Mode, but my curtain is quite heavy so the motor has to do more effort. Like all other Switchbot items I own, there was no problem adding curtain to app. Calibration was a breeze. The app has too many opinions for controlling curtains in this review, namely times, triggers, scenes etc, but most scenarios you could ever think of are catered for. I like the manual control of curtains, so other people who are not aware of the smart controls can still operate curtains. Maybe the solar panel might be a nice add on at a later date. Would be a great option for people with hard to reach curtains namely the ones behind sofas etc. Particularly like the fact that I can schedule opening and closing, so the house has the illusion of being occupied. This is a security feature that might be the reason you are thinking of fitting smart curtains in the first place. Of note, if you have a metal pole and metal grommet curtains that are hard to open/close manually anyway, you might want to consider fitting felt strips to the inside of grommets prior to turning them into smart curtains. I have done this throughout my house and the curtains now glide rather than tugging.

### ⭐⭐⭐⭐ Excellent Build Quality with One Minor Physical Quirk
*by U***T on 17 December 2025*

The first thing I noticed is the excellent build quality. Setup was a breeze, and I appreciated that it works easily with or without the alignment magnets. A standout feature is that the dedicated hub isn't mandatory; being able to use SwitchBot relays as a hub is a huge plus for flexibility. The only issue I encountered is that the bottom of the curtain tends to catch, preventing it from closing fully. It seems the curtain needs a bit of extra weight at the bottom to keep it aligned, though the top part moves perfectly without any issues.
