Curtain Control Node.

[AWI]

@Tore-André-Rosander Nothing wrong with you interpretation. I have not written this sketch as a complete S_COVER implementation. Only the V_PERCENTAGE part (not V_UP/V_DOWN). If you define it in Domoticz as "Blinds percentage" (see my previous post) it will work. Sorry for the confusion.

[Tore André Rosander]

@AWI Seems like my problem is with Domoticz itselfe.
I have the same problem as described in this post https://www.domoticz.com/forum/viewtopic.php?f=6&t=7748

[AWI]

@Tore-André-Rosander You can probably solve it by deleting the sensor in Domoticz and let the sketch present itself as S_DIMMER (and use another sensor id)

[Tore André Rosander]

Maybe its because i have not calibrated it? I dont have any pushbuttons laying around, so im gonna make one with some wires. But i see that there is two pins defined as buttons. Should i use the buttonPin1 as VCC?

So it would look something like buttonPin1 -> buttonPin2 -> button -> gnd?

[AWI]

@Tore-André-Rosander You can ignore buttonpin2. Just connect your "button" to buttonpin1 and ground.

@AWI I'm curious where you got the rails for the curtain. I wasn't been able to find them, but stumbled on this topic.

[AWI]

@TheoL Ikea :smile:

[TheoL]

@AWI Really interested in the mechanics ;-)

I'm currently working on a similar project, only I got started with 24V DC motors that I got from my work (left overs from a test project) These motors are very strong (way way over rated) and have a big gearbox what unfortunately makes the movement a bit slow.
I started off with 1 motor to move 2 curtains at the same time, but will change this to 2 motors for either side since the better half of me likes to control the curtains separately in case she only wants to close 1.
Next to the automation there will also be a manual control switch be hidden behind the curtains in case the node is down and I'm not at home to fix the issue...
all running on an ESP8266 (ESP-12e) unit to have it over WiFi and have enough io

Currently the test setup is working fine and I'm ordering parts to start implementing this a bit bigger in the first room. the test setup I made with some old wood 1 meter of rail and a few old rugs as curtains...

I use a GT2 timing belt that is commently used for 3D printers and pully's are widely available as well as the belts in different lengths (I order them on rolls of 10 meters) and attached the timing belt to a carriage that is normally to pull the curtains with a rod.

the motor is mounted on a bracket with currently 2 end stop switches for open and close (but will be 1 switch for open and 1 for close in the final solution)

resulting in driving the curtain from 1 side

electronics are working fine now and need to be ported to a test print and later to a real PCB design

     Serial.print("Message - valid: ");
     Serial.print(message.sensor);
     Serial.print(", Unrecognized ");

  }
 
}

When the program I have uploaded to my mysensors, the engine still turns, one left and one to the right and did not work the button blinds in Domoticz.

I cant turn off my stepper motor in Domoticz.

your wiring diagram is not accessable:
Error (403)
It seems you don't belong here! You should probably sign in. Check out our Help Center and forums for help, or head back to home.

i use a DC motor so can't help with stepper motors, but can you share an image of how you setup your rails?

Now the wiring diagram should be visible.

[jacikaas]

Hello,

I trying to adopt the code for 28BYJ-48 stepper motor with ULN2003 driver board for roller blinds control. Code is working, but when the stepper motor is always on - it gets hot. Because of it also its consumes more energy. So thats why I want to turn on ULN2003 board only when new action is started, and after that it should be shuted down again. I could do it, because ULN2003 has On/Off jumper:

Question #1: I trying to use relay for that On/Off. Could I do it without relay and control On/Off jumper directly from arduino? Does relay is the best solution?

Question #2: I suck at programming, but I trying to add theese lines to my code to control the relay SIL05-1A72-71D, which controls the ULN2003 driver board:
int powerPin = 7; //before SETUP
pinMode(powerPin, OUTPUT); // In SETUP
digitalWrite(powerPin, LOW); // In SETUP
digitalWrite(powerPin, HIGH); // In void receive function
delay(CURTAIN_CLOSED); // In void receive function
digitalWrite(powerPin, LOW); // In void receive function

digitalWrite(powerPin, HIGH); - I think is in right position, but I don't know how to turn off relay when action is done. Please advise for coding, because I not good in it. Thank You! Below is the code:

// Enable debug prints to serial monitor
#define MY_DEBUG

// Enable and select radio type attached

@jacikaas said in Curtain Control Node.:

void receive(const MyMessage &message)
{
// if message = V_UP start moving until closed
if (message.type==V_UP) {
digitalWrite(powerPin, HIGH);
if (stepper1.distanceToGo() == 0){
if (stepper1.currentPosition() == CURTAIN_OPEN){
stepper1.moveTo(CURTAIN_CLOSED);
// Store state in eeprom
saveState(message.sensor, message.getBool());
request(CHILD_ID, V_UP, 0); // request new values from controller
}
}
}
if (message.type==V_DOWN) {
digitalWrite(powerPin, HIGH);
stepper1.moveTo(CURTAIN_OPEN);
// Store state in eeprom
saveState(message.sensor, message.getBool());
request(CHILD_ID, V_DOWN, 0); // request new values from controller
}
if (message.type==V_STOP) {
digitalWrite(powerPin, HIGH);
stepper1.setCurrentPosition(0);
// Store state in eeprom
saveState(message.sensor, message.getBool());
request(CHILD_ID, V_STOP, 0); // request new values from controller
}
// delay(CURTAIN_CLOSED);
// digitalWrite(powerPin, LOW);
}

You can enable and disable outputs and try. In the following function:

void receive(const MyMessage &message)

//add the following at the begining of the function
stepper1.enableOutputs ()
//and add the following at the end in the same function.
stepper1.disableOutputs ()

I hope this helps haven't tried it myself.

[jacikaas]

@suresh-mali Thank You Suresh for Your answer!
I disconnect relay and delete it lines from the code.

I add lines to code like You said:

void receive(const MyMessage &message)
{
stepper1.enableOutputs ();
 // rest of code
stepper1.disableOutputs ();
}

It looks like it have to work because it is simple solution, but it doesn't... On driver board ULN2003, when motor is not rotating, A Led is always on. I think if command with disableOutputs would be activated, then the LED should not be on?

[Suresh Mali]

@jacikaas Ok.

//Remove this line from loop function
stepper1.run(); 

//Change this line
stepper1.moveTo(CURTAIN_CLOSED);
//to
stepper1.runToPosition(CURTAIN_CLOSED);

I hope this works. Also make similar changes in block which closes curtains.

@jacikaas Sorry to revive an old thread, but did you get this resolved and if so how?

I just 3D printed my first motorised roller blind mounts and have tested with arduino stepper only.

Next is to go mysensors with it, but which way is best? Standard arduino stepper or accelstepper?
