You can purchase a hardware kit here. If it's sold out, PLEASE sign up to the waitlist. It's the only indication we have to make more. If you don't, then we'll NEVER make more.
Without the kit, it's a pain to source all the parts, and costs a lot more because you'll be forced to buy 100 screws (when you only need 2) and 100ft of rope (when you only need 30ft) at a time.
I've written a short book to teach you how to program this Trinamic stepper motor from scratch. It can be found here
The Ropener is a smart curtain opener that uses two buttons and HTTP requests to open and close your curtain. Combine it with Node-RED, Home Assistant (via ESPhome), or any other system capable of sending HTTP requests and get your curtain to open and close automatically.
The motor is attached to your wall just behind one of the curtains
There is a carriage attached to the back of each curtain panel. A string runs through each carriage and through the motor which pulls it open and close.
At the heart of the device is our custom PCB which uses an ESP32 and Trinamic TMC2209 stepper driver.
The motor is dead silent.
If a stall occurs, the advanced TMC2209 will detect the increased back-EMF from the motor and stop it automatically, like magic.
This works on backtab curtains that looks like this:
Or with curtains with rings, like this:
We've created a hardware kit that includes everything. If you source the parts individually, it will cost 5X more just because all of the hardware need to purchased in bulk from places like McMaster-Carr. You may optionally 3D print your parts.
- Total print time: ~12 hours (You can also purchase the 3D prints)
- Total assembly time: ~20 minutes
Go to the repo folder "hardware" -> "Plastics" -> "platter"
Either use command strips (which is recommended) or 4 small nails (for drywall only), or two screws/anchors. It's very easy to install.
