Thanks!
What kind of power supply (V/A) are you using @FF-Fox ?
12V/2A. Connected to the A4998/stepper and to a buck converter (cheap LM2596 module) for the Wemos D1 mini 
I also used a 12V/2A power supply with a A4988 driver and NEMA 17 but it failed to lift the roller blind. With a luggage scale I measured that about 2.1/2.2kg is needed to lift the roller blind and I assume the NEMA should be able to do this? I put a custom made wheel directly on the NEMA which is driving the robe of the roller blind. Should this work without additional gears you think?
Depending on your blind and speed, maybe.
I needed the gearbox for my blind as the NEMA wasn’t able to lift the blind without it…
I’m trying this github project;
When i flash the NEMA_ROLLER_BLIND.ino to my WEMOS D1 Mini the AP is working but after connecting to my own wifi reconnecting al the time (looks like reboot).
When i flash the motor_on_a_roller_blind-ws_060918_Working.ino nothing works…
This project looks exact what i need, anyone the setup with the NEMA17 and L298N H Bridge?
Hello. I was trying to use this code, together with this example from the doc:
But I get an error from Cover Template:
position_action is an invalid option [cover.template]
What is going on?Was this option removed?I also don’t see it in the ESPHome documentation, which really sucks…
You need the 1.15-dev version of ESPHome for that.

So everything works almost perfectly, here is my code if anybody wants it. It also keeps track of the current position, so when the power is out or anything unexpected happens, the stepper position will be reset to the saved one. I also have different speeds for closing/opening, since I can close the blinds faster that opening due to them being quite heavy. I also have a relay connected to my heating, but that is another point.

I have a problem though. I don’t know why, but it seems like the stepper goes a full rotation, and then pauses for a fraction of a second, and this cycle repeats until the stepper gets to the desired position. Not sure what stepper library it is used, but I am guessing that my loop function takes to long to execute maybe?Or it might be because I use the a4988 driver with the sleep function in ESPHome, but the sleep pin is actually connected to the enable pin of the driver. But this worked well with my custom code, I woke the driver before I need to change position, and after the stepper was in the desired position, the driver was disabled, not sure how ESPHome does it.

How long are the wires between your a4988 and the motor? I’m seeing similar issues, still figuring out of I can extend the wires between the a4988 and my 28byj-48.
Quite short, it worked fine without Esphome before, so it has to be something to do with this. Also, I think that when I first started testing with only the a4988 esp home integration, it worked fine, so I am guessing the esp8266 is too slow to handle everything.
First of all this project is awesome! I followed this guide here: Motorized WiFi IKEA Roller Blind : 11 Steps (with Pictures) - Instructables
But it ended up being to weak, so I got a nema 17 stepper but it is capped at 350mAH…
I would like to mount the nema directly to the window ceiling and put on a cap on the nema to be inserted directly into the tube. (I have cut the blind according to the link above…)
I see a lot of people are doing the gear box version, is that the only way to get this to work?
Im just wondering if I again need to order a new stepper motor or if that will work to pull a 180x180 cm blind(https://cdn-shop.adafruit.com/product-files/324/C140-A+datasheet.jpg)
I plan to use a DRV8825 and a wemos d1 mini.
Hi @JBS,
I am using DRV8825 drivers with NEMA 17HS4401 in ESPHome (although not officially supported.) The DRV8825 is almost plug and play with the A4988 - there is just a minor difference in connections:
-
EN(able) pin is an active low input - the DRV8825 is enabled by default. To disable, you can pull it high. I leave mine detached.
-
SL(ee)P pin is also an active low input - the DRV8825 is in sleep mode by default. I’m wiring this to ESPHome’s sleep_pin for the A4988
-
R(e)S(e)T is again an active low input - the DRV8825 will ignore signalling on the ST(e)P pin unless you pull it high. Now here’s the part I’m not sure about: this pin is also used to reset the driver to HOME, but seeing as there is no VDD on the DRV8825 as there is on the A4988, I’m attaching this to 3.3V from the ESP8266, so keeping it high. Anything from 2.5V to 5V should be okay.
So far, so good. When SLP is low, there doesn’t appear to be any power going to the motor. It appears to be fine to leave RST on 3.3V.
I haven’t played with the F(au)LT pin at all, which is in the place of the VDD on the A4988. Everything else is pretty much the same.
I wound up with a few NEMA 17HS4401’s and the DRV8825 gets pretty hot even after just 15-20 revolutions - heat sinks are a must! This may be because my power supply is not rated for the 1.7A 17HS4401’s though. I’m just starting out with steppers, so still learning.
The 1.7A NEMA 17HS4401 is pretty strong when it pulls, but freewheels without power. Probably good for a stiff blind that is sprung to remain in position once moved.
Anyone else experimented with ESPHome and the DRV8825? Basic config is:
stepper:
- platform: a4988
id: stepper_one
step_pin: D1
dir_pin: D2
max_speed: 200 steps/s
sleep_pin: D5
acceleration: inf
deceleration: inf
- platform: a4988
id: stepper_two
step_pin: D6
dir_pin: D7
max_speed: 200 steps/s
sleep_pin: D8
acceleration: inf
deceleration: inf
Kind regards, Dave.
@dhartsmith Thanks for your explanation 
Got my NEMA 17 and A4988 also wokring with ESPHome. Will try it with the DRV8825 when it is arrived from China.
Also need to print some new gear/wheels with a better balance between torque and grip.

Hi all,
Great great topic. I am planing to do a DIY project based on the NEMA 17 + A4988, i.e. a 1-axis solar tracker based on magnetic compass measurements and the sun azithmut course among the day.
I just compiled some first example found here in this topic with a cover… but my motor don’t move at all.
Since this project is an outdoor one, I am powering the electronic with a 3S LiPo battery (up to 12.4V). A 5V stepdown regulator is used to power the ESP8266+ QMC5883 compass.
Anyone can confirm the exact pinout I have to follow ? From my current ESPHome model, the SLP pin is D2. No need to use the RST pin too ? or the ENABLE ?
Thanks in advance…
EDIT: I think my A4988 is smoked 
To be more precise … Since nothing worked with the pin D2 connected to SLP. I tried then connect RST & SLP togather as depicted in many blogs. It worked from HA with the cover object. then;… I decided to connected also D2 to SLP with still SLP & RST connected… then no more mouvements :(… I tried everything. Recheck 100x time connexion :(. I am afraid the A4988 is gone. There is a way to test it wiithout oscilloscope ?
Hi all, I’ve been reading this thread for a while and I though I’d give the blinds a go. I originally used the Motor on a roller blind and have 4 blinds running on it, however, I do prefer ESPhome.
THIS IS NOT A DIRECT REPLACEMENT FOR THE SAME WIRING AS THE ‘Motor on a roller blind’, the next post is.
The following sketch is complete, other than the passwords. It has one button and can be set up in situ. Hold the button down to enter setup mode, press again to start moving to the bottom, press at the bottom and it starts moving up, press again at the top and the blind is calibrated.
Location and action are stored in memory and it will remember where it should be, even after power loss.
I’ve have done a little testing and so far, so good. It could probably do with an LED to display setup mode, but it’ll be fine.
I wrote this and didn’t think of the 4 blinds I already have that have NO button, but I’ll sort it out
This setup uses a Robotdyne ESP8266 Wifi D1 Mini and a 28BYJ-48 stepper motor + ULN2003 driver board.
# Press button for > 1 second to enter setup mode

# Press button again when closed and blind starts to open (actually resets the stepper position to 0)

This IS a working replacement for the ‘Motor on a roller blind’ sketch. I have it set up on my kitchen blind that has been running the original ‘moarb’ sketch for a year or so.
I couldn’t find a way of sending it OTA, maybe someone else knows a way.
To upload via WIFI, go to this page and follow the instructions, took less than one minute to upload and configure!
Here it is for your scrutinisation
Also, On GitHub
EDIT: Positioning now works.
# This sketch will add 2 switches named <upper_devicename> Setup Switch and Setup Button
# Use your mobile or tablet and connect to http://<devicename>.local to set up the blind
# Turn on the Setup Switch to enter Setup Mode and use the Setup Button as shown below to setup blinds.
# 1) Turn on the Setup Switch to enter setup mode
# 2) Press Setup button to start the blind closing
# 3) Press Setup button again when closed and blind starts to open (actually resets the stepper position to 0)
# 4) Press Setup button again when blind is fully open
# 5) Job Done

Hey @RoadkillUK
Awesome work! Thank you so much for sharing!
I tested this out and wanted to report a few things and ask a few questions
- ESPHome is concerned about the ‘position_action’ of the cover and says is not supported. I had to comment the whole section out to get it validated.
- During the setup stepper starts moving the blind up instead of down in the first place in both pin configurations (readme says the opposite). The only problem with this is that 0 is always set for a fully open position from what I understand and so HA reverts open and close buttons.
- Is there no stop action? Unless ‘position_action’ is meant to achieve the same thing.
- Is there a way to configure open and closed positions steps manually?
- And is there a way to adjust this for two blinds?
-
Previously it would only compile on the ESPHome 1.15 Dev version, however there has just been an updated version of ESPHome Beta which is what I usually use.
-
Oh, I’m surprised, I’ve tested it and changing the pins should work, can anyone else confirm this please? (silly question, but have you wired the motor the same way as in the original MOARB?)
-
I’ve just added one, use the Github link.
-
Position now works, I have added the following to Lovelace and it shows a slider to adjust the blind, you will also need Lovelace Slider Entity.
- type: entities
name: Roller Blind
min: 0
max: 100
step: 10
entities:
- cover.roller_blind
- type: custom:slider-entity-row
entity: cover.roller_blind
- I’m sure there’s a way, but I’m not doing it
Regarding the positioning, it’s not 100%. When you press the stop button, the slider doesn’t change to the correct position. When not fully open or closed, it will only allow either up or down, this is to do with the single button function as it needs to know which way to go.
If anyone wants to take a look and improve it then please do
I think I’ll have to rewrite some of this as it’s mainly ‘functional’

Thanks @RoadkillUK
I’m using ESPhome 1.14, please disregard the rotation direction, I think it was late night and I messed up the connection after all experimenting. Thank you for everything else but I guess I’ll be moving on Need to configure 4 blinds (2 x 1 ESP). Will try to figure out your code for the parts I’m struggling with if you don’t mind
Right, I’ve done a big rewrite and it took me ages but at least I’m learning.
It still only controls one blind but it does it well, has positioning etc. and is a straight swap for MOARB.
