    Motorized WiFi IKEA Roller Blind

    I just finished two modules (finally). Some modifications I made:- used ssvenn‘s code fork, including 9v mod- different component housing to accommodate for the added buck converter and make it fit to my window- made them left/right sided since my windows are recessed and the blinds already hit the side when I open it more than 90%- cut off one of the noses on the motor to turn it sideways and reduce the distance from the window (again to help with the wall clearance)- modified mount since my shades are not IKEA but some generic ones from the home improvement store- HomeKit Integration with Homebridge-MQTT-blindsStill having some issues with the one mounted on the left side, didn’t get too much into the code, I think right now it thinks down is up and up is down, but thankfu...

But all in all, great project with some roadblocks though. Anyways, I already started to build a unit for my old gas heater thermos:)

    Yes, check out the tip I posted above as well as the pictures by ssvenn. You have to modify the motor shield - there's no way around it

    The board layout seems to have changed since this intractable was originally published. It's all in the comments somewhere, so here's a little heads up (thank you @ssvenn for helping me with this) I was confused because there is some explanation to the pictures, but no explanation as to why those steps are necessary.- You must (there's no way around this unfortunately) solder the wires to the motor shield and connect them to GPIO 2,3,6 and 7. Jumper wires help cut the soldering in half, but the chip is pretty tough, it's doable though- Remove the highlighted resistors and the transistor. According to ssvenn, if you want to power it with 9v, leave one of them in place (I don't know which one though). If you remove the highlighted ones, you're "stuck" with 9v- get a cheap buck c...

If you remove the highlighted ones, you're "stuck" with 9v- get a cheap buck converter and preferably some connectors to fit your power brick (like these https://www.amazon.de/gp/product/B019HAC6V4/ref=o... and integrate them into your box (basic 3d modelling skills required)- Attach one wire from the 9v output directly to VM, the other one to the buck converter and from there to VIN. Same for GND. Purpose of this being that you only need one power source, it is technically possible to still power it over USB and have the 9v. That's what I'm doing for testing purposes right now

    @Bitsy21: Mine doesn't even vibrate. I found some documentation on the stepper used and the sequence in the code matches the one provided by the manufacturer (check out this instructable: https://www.instructables.com/id/BYJ48-Stepper-Mot... not a solution, but it gives some insight on how a stepper motor works)It's really frustrating since everything else works and if fails due to this seemingly minor issue that nobody else seems to have :/

    Motorized WiFi IKEA Roller Blind

    Hey. I finally received my parts today and couldn't wait to try everything but now I'm stuck.First off, I ordered the parts exactly as described, only difference being the manual switch which I picked up locally. I flashed it - check. Did the WiFi fix - check. WiFi connection established - check (according to my router) Ran it in ESPlorer - worked.However… the motor does nothing. When I enter the code in ESPlorer, the blue light lights up and goes off after a couple of seconds, giving me a confirmation that the new status is now X+/-25. But it doesn't rotate.I tried wiring it as depicted, then I changed it like it's described in the stepper.lua (A+ Pink, A- Blue, B- Yellow, B+ Orange, VH(?) Red) but it still doesn't move.I ordered two motors/boards since I have two blinds, neithe...

    Instead of hammering them on and accepting that it will wear out over time, I would drill a 1 1/2 inch hole in the top or bottom that meets the end of the hole for the rod. Not all the way through, of course. Then use some washers and a nut and tighten it. Plug the top of the hole with a plywood circle and you have a clean and easy to disassemble solution.Plus, there's rods that have a regular wood thread on one end and a machine thread on the other, I'm not sure if I would trust screwing a machine thread into wood.
