The solar panel can supply unlimited power to the Curtain 3 according to SwitchBot, as long as it gets 3 hours of sunlight per day. It’s attached permanently with a clip via USB-C and hangs behind your drapes facing the window. The Curtain 3 bot carries the solar panel whenever it moves, keeping the battery charged at all times. Bluetooth connectivity is handled through the BM-8762CMF Bluetooth 5.0 BLE Module [ Datasheet] manufactured by CC&C Technologies in China, which is based on the Realtek RTL8762C [ Datasheet] Bluetooth low-energy SoC.

Now go and create a Script using the below YAML code. This script calls the REST command with the requested curtain position. It then loops around waiting for 30 seconds each time and updating the curtain position sensor. It does that a few times because it takes so long for the curtains to move using QuietDrift. alias: Curtains Set Position Quiet If you have tabbed curtains then there are adapters you’ll need to fit for those, and if you have an extendable pole then you’ll need to fit the included adapter to your pole too so as the robot can make it over the step. The QuietDrift mode is extremely quiet at the price of battery life and speed. It’s hard to actually put a noise level to it, you basically hear nothing! The drape rings moving and creating noise is what you will hear, not the SwitchBot Curtain 3. This mode is great for opening the curtains in the morning when you are asleep. If you want remote control, you need to install the SwitchBot Hub Mini, which can also act as an IR transmitter if you want to control practically any device, from a TV to air-con. With the Hub installed, your SwitchBot Curtain will automatically communicate with this device (provided it’s within Bluetooth range). That gives you remote control over your curtains, including scheduling.

I like the convenience of automatic closing curtains. It's handy! I set it to close the curtains at dusk; it helps keep in the heat and saves me a chore, something I've often forgotten before bed. But it's hard to look past the aforementioned issues. What is it with teenagers and curtains? They either don’t bother closing them when it gets dark, or they never open them during the day. SwitchBot have very kindly offered to help me with this little problem. They’ve sent me a pair of the new SwitchBot Curtain 3 robots which are designed to turn almost any type of curtain into a smart curtain.

My wife and kids were perplexed by my excitement as I gathered them by the window to unveil a mysterious new gadget. With all eyes on the curtains, I tapped a command on my phone. The room was heavy with anticipation. After an agonizing 10-second delay, the left curtain jerked open in spurts. A few seconds later, the right curtain tried to join in but moved less than an inch and made a very unpleasant, high-pitched whine that lasted about 30 seconds.Take a closer look at the ‘parameter’ value – the number ‘1’ means that QuietDrift is enabled. If you don’t want to use QuietDrift, change this to ‘ff’. To be honest, if you don’t want to use QuietDrift then you are better off using Matter, but perhaps you have your reasons! Save your configuration and restart Home Assistant to make sure the REST command entity has been created.

Like other SwitchBot products I’ve tested, the Curtain 3 is built really well and feels like a premium device. It’s certainly a significant improvement over the Curtain 2, but if you already own the previous generation of SwitchBot curtain motors I do not feel it’s necessary to upgrade. The installation is super easy and took me maybe 5minutes, including wrapping the connector rod. The included beads fixer can be used to even out the distance between the ring in grommet curtains. I did not do this, since the bot operated without them just fine. Provided you have the SwitchBot Curtain installed correctly, and it isn’t too tight, it works brilliantly. There’s a pitched whine to the motors as they power your curtains open or closed, but the system worked flawlessly for me over a period of weeks. SwitchBot is running a sale currently in various online stores, here’s how to get the most of it depending on your location.Curtains operate in performance mode by default, closing and opening at the maximum speed. There’s a quiet mode that reduces noise at the expense of speed. To be honest, the SwitchBot Curtain is so quiet anyway that most will find that there isn’t a need to change modes. The new SwitchBot Curtain 3 is much quieter than the Curtain 2 model, as it has a QuietDrift mode to keep the noise level at only 25 dB. This mode is slower, but it makes for a quiet, less distracting experience. SwitchBot claims these will outlive the other components, noting that the rubber roller will need to be replaced after 10 years. This is such a long period to even think about, let alone worry about the curtain roller. Installation
