@mfalkvidd I have hit a dead end. The issue described in the thread is stii not resolved. Any advice on what can help figure out the issue would be helpful.

Thanks

Any Moderator or Admin here who can help me, please.

@rejoe2 I am using 2.2.0 on both gateway and node. Using NRF24L01+ with Caps . Strangely one of my node running on 2.1.0 is able to communicate with the gateway. Let's hope Mods have some answers. Appreciate your efforts and time.
Thanks

@rejoe2 I have already tried 2 different RF modules, the known good ones. So RF can be ruled out. I am running it with Domoticz, usually I don't have to change any setting, on presentation the node is shown in Domoticz and I just add it to my UI. Also tried the option Allow discovery for 5 mins in Domoticz that did not work either. So kind of lost here as to what's happening.

@rejoe2 I tried as suggested. Cleared EEPROM using the sketch from MySensors example folder, tried auto ID assignment and also predefined ID. None seems to work.

This is the log when no ID is assigned.

Please advice if there anything that could help me understand the issue and fix it.
Thanks alot.

@rejoe2 Will try that. I did tried assigning ID manually, but that did not work.

@rejoe2 oh, I am sorry. I use the sketch from EEPROM Lib in Arduino. Not from MySensors. I am doing it right?

@rejoe2 I have used the Mockmysensor example sketch from Mysensors.

I updated the gateway to 2.2.0. I have one sensor on 2.1.1 which able to communicate fine with my gateway. I tried testing a node on 2.2.0. I flash the MockMySensor sketch, but its not able to get a node ID from gateway. I also cleared EEPROM and replashed , tied to assign ID to node but did not help. The ID:4 we see in the gateway log is my node running on 2.1.1. Need help in understanding what could be the issue/fix. Thanks

Thanks @mfalkvidd and @gohan . That helped.

I build a Gateway on Rpi. Post build it was working fine. I reboot and it stops working. Unable to interpret what this means. Please help. I did go through the forum but not able to solve it. I am using the latest 2.2.0 release. I ruled out hardware and radio issues as one of my node was able to communicate and send messages.

Any help would be appreciated.
Thanks

@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.
Refernce article: https://www.pjrc.com/teensy/td_libs_AccelStepper.html

@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.

@TON-RIJNAARD You need to select the board based on the bootloader you have flashed. Complile the code in Arduino and try burning the hex file using a programmer (USBasp, AVRISP, etc..) if are facing issues with Arduino.

@Tmaster Thanks for bringing this up. I was able to find LNK family ICs where I'll be able to source at cheaper price. I have ordered some LNK306 to test them. Cost me 80Rs/$1 and some cents. Will test once I receive them and post the results.

@rvendrame My current design uses Hi Link 5V PSU, however I am looking at lowering the cost and this was one of the options.

I also reverse engineered some cheap 5v phone chargers, its an SMPS based design using single transistor. Are safe as there is isolation.

This might be my next option to look into. The problem is with the transformer. How do I get the transformer to my specification. Do I wind them myself? will have to look into it.

@Suresh-Mali I modified the above schematic, just to add some protection and regulation.

@Toyman That helps. Thanks.

@sundberg84 Thanks for your valuable information.

@gohan Overvoltage and short I guess can be solved if I use an MOV and Fuse.

If nobody is going to touch it once installed, would there be any safety issues?

Hi,
Can I use a Capacitor-Resistor voltage dropper circuit without isolation to power up my Node like the one in below image.

I understand the node would not be mains isolated and would be a risk if touched. Apart from this are there any other risks or performance issues that I should be concerned of before I dive into constructing this circuit. I will add a LDO regulator at the output to get a regulated supply.

Please share your thoughts and views. Thanks

@TON-RIJNAARD There is a ICSP header to program MCU. I dont use RFM69 so you'll have to modify the Sch file. NS pin connects to D10. More info here : https://www.mysensors.org/build/connect_radio shows on how to connect RFM69.

@TON-RIJNAARD
SparkFun-DigitalIC.lbr This lib has the ATSHA204.

https://www.diymodules.org/eagle-show-object?type=usr&id=1937&part=microchip.lbr&device=25* here you can download the EEPROM lib

@TON-RIJNAARD I'll get back with libs for these parts. I am not in town and all files are on my desktop. Will send you once m back

Hi @patrick-schaerer ,
I got my setup running and was trying your code.

I was testing this code on my AC unit which has 1600W max consumption. When I first ran it always reported a value of around 270W even when the AC unit was off from mains and in running condition it reported around 750W with compressor on and around 250W with compressor off.
I adjusted the value on line

emon1.current(ANALOG_INPUT_SENSOR, 30);             // Current: input pin, calibration

Tried values from 10 to 111(default as per emon lib) to calibrate it to report 0 in off condition. finally at 10 it reported zero but now when the AC is on it reports 270W max.

Could you please help me figure out where the problem could be. Thanks

@checkup I was trying this app and accidentally put in wrong IP address. The froze and had to end app. I have submitted the log report.

After filding around a lot with the MySensor2.0 lib and spending my whole weekend, when I could not get things going I finally switched back to MySensors1.5.4. After that I made quick progress and my node was on network. Here is the link below of a working Dimmer node.

MySensors AC 220v Dimmer with Domoticz – 01:42
— S Kumar

I tried debugging with MYSController. It seems the node and gateway are not communicating. The Gateway receives the messages but does not assigns ID to node. I tried assigning static ID to both Node and Gateway, but its fails.
What started as Dimmer module not working has turned to no communication between nodes on 2.0lib.
I'll probably wait until the MySensors 2.0 lib is stable and there is proper documentation. For now rolling back to 1.5lib seems the best choice I have got.

The forum is there to help but it has mix of 1.5 and 2.0 lib its like hunting in a haystack for documentation and support. Please find a way to separate the 2.0 and below 2.0 lib. Thanks

I am still unable to figure out why the node is not getting registered on gateway.

What could be the failure here. Itried clearing the EEPROM on both Gateway and Node, changed power supply on Node, but nothing is working.
I know Gateway is fine because I had another node and it sends data and it shows up on Gateway.
Somebody please help. Thanks

Hi,
I had a similar setup, the Ultrasonic sensor did not last long. I used to measure the water level in overhead tank. Within a month the transducers were all rusted and the ultrasonic sensor died. I had to take everything out. I am looking for some waterproof sensors like the ones used in car park assist.

In case you have a better solution, please do share.

@jemish You can look for on Aliexpress.

@bisschopsr The design files are available on openhardware.io

@oscarc The routine below i see some problem.

void checkHWInnputs()
  {
 debouncer.update();
   debouncer1.update();
  int value = debouncer.read();
 int value1 = debouncer1.read();
 
  
   if (value == LOW) {

 Serial.println("Detected stop button push. Stopping");
     cover(1);
  }

   {
   if (value1 == LOW)
  Serial.println("Detected stop button push. Stopping");
      cover(0);
    
    }

Once you detect the button state, you are calling

cover(0);

If you look at the cover routine, the parameters are used in case statement.
0=Open
1=Close
2=Idle.
My suggestion would be to change cover(0)/cover(1) to cover(2) which would stop the motor.

@oscarc You can add debouncer.

  debouncer.attach(BUTTON_PIN);
  debouncer.interval(5);

Refer the binary switch sensor sketch here http://www.mysensors.org/build/binary

@patchmaster I used the relay sketch and modified it to my needs. Sorry but I dont have any sketch for ULN2003.

@barduino Seems like the IDE. Open any example MySensors Sketch. Delete the contents from sketch and copy paste from my sketch. I guess that should work.

Are you able to compile any other sketch in Arduino?

I have published my project with all the files.
https://www.openhardware.io/view/45/Curtain-Control-Node

@franzelare Great. Good Luck with the build.

I'll be posting my HW design and Code as part of Contest on openhardware.io

@barduino I tried downloading the code, it works. Anyways I am pasting the code below.

For end stops I have not yet decided. I had some Ideas of using Hall effect sensor on both ends and a small piece of magnet in the string to detect ends or Maybe use stop switches. Not sure but will have to try both and see which works the best.

I am yet to clean the code I have some debugging serial prints in code which will remove once finalized.

@AWI Thanks. Why dont you increase the pulley size (larger pulley) that will increase the speed.

I found driving stepper motor to be bit more complicated than driving a DC motor. I picked the Geared motor basis the calculation using this calculator.

Since without rails pulling the curtains on a metal pipe needed more torque. Thus I chose 100 RPM to be a suitable fit.

Will share the Schematics and PCB layout files soon. I have already added the sketch for reference. Since I was testing I did not put the circuit in any housing. But will give some shape soon.

Also will be adding 3 buttons for Manual Control.

Its a Geared DC Motor with Voltage Rating of 6-12V and 100 RPM. I am using a L239 to control the motor.

My First version of curtain control Node is ready, installed and tested. Some work is pending, which I'll complete on my weekend.
Edit: Code for the Node:Curtain Node
Curtain Control Node.

Please share your feedback so that I can improvise.

@mfalkvidd AVRDudess works with AVRISP mkii as well. Have you tried to detect the Pro Mini chip using AVRDudess+AVRISPMkii. Are you able to detect the chip using Mkii in AVRDudess?

@mfalkvidd Do you have an USBasp? It works great burning bootloaders. You will be able to recover the fuse as long as you have not set the fuse to disable SPI. If SPI is disabled then the only way to recover is using High Voltage Programmer.

@mfalkvidd If the ATMEGA is detected then all you have to do is input the Fuse Bits and program. It should work. Just select the bootloader hex file in Flash. Check Set fuses and hit program.

@mfalkvidd As long as you have not disabled SPI fuse you should be able to recover. Try AVRDUDESS with slow speed. Also on USBasp there is a jumper for slow sck speed. That helped me recover/reprogram fuse to Blank ATMEGA328p as well.

I have been through the same scenario. My savior was USBasp and AVRDUDESS

Select programmer and click detect. If the device signature is found you will be able to set the fuse bits. Get the fuse bits from boards.txt in Arduino folder. I prefer using AVRDUDESS rather than Arduino to burn bootloaders. Its very convenient and easy to use.

Here is the sketch for Curtain Node.
WindowCurtainShield.ino

I have managed to solve a lot of problems, but some still exist.
Works great with Domoticz..manual Buttons are still WIP.
Some pictures for my first version of Node.
I have left EEPROM and ATSHA204 unpopulated. Will learn more about it and then add.
I will be using Dual Optiboot to support OTA.

Hi,

I have a problem with water supply. Sometimes the water has very bad odor and cannot be used. The only way to check is smell the water. Now when the water supply is on and filling overhead tanks, at beginning the water smells OK, but you don't know when bad water will start flowing. For now we do random checks every now and then to ensure, but sometimes we miss and it gets pumped up contaminating the entire tank. The only way is to drain the tank and refill.

Is there a sensor that can be used to check the water quality. I read some blogs suggesting use of IR and photo diode and reading the values of photo diode. This could be helpful when there is dirt in water but not smell. Please let me know if any one has any idea how this can be achieved.

Thanks for reading.

@scalz Thanks for clarifying. Anyways, I will still be able to use the EEPROM. Will keep it for future when you have the modified code for i2c protocol. For now I'll have to order ATSHA204A-STUCZ package.

Using the reference from https://www.openhardware.io/view/18/OTA-and-Authentication-Evaluation-Board
I modified the design a bit to accommodate ATShA-204A-SSHDA package.

Is there something I need to change in the code to use 8 pin ATSHA204.

@ericvdb I tried with MYSController. Set Assign ID to Auto, also tried settings up static ID, but does not seem to work.

I have also tried other sketch on same node and they work fine.

Hey Guys, I managed to find a EEPROM chip from Bangalore, India. Its 25LC512, priced at Rs.65(~$1). I hope it works. I should get it next 2days. It has the same footprint as one used in SenseBenderMicro. Will try once I have them and update.

@scalz Oh yes, soldering is not an issue. I have rework station and I am proficient with soldering Through Hole and SMD components.
Its about getting the EEPROMs.

Buying from Ali would be my last resort. I am hunting for this chip in other parts of India. I should have an answer by day end, If I dont get them then I'll order from Ali. Waiting is the worst part of ordering from Ali. I had Order ATSHA204 on 12th Dec and still waiting.

@scalz , Thanks
I am not a Device Programmer, I am counting on some one to hack and make it possible. Hope somebody puts in efforts that will help everybody like me.

@ahmedadelhosni Hey, I found this article. Seems like the guy has used i2c for remote flash. I was not able to extactly understand whats going on, maybe you can help.
http://www.rotwang.co.uk/projects/bootloader.html

@ahmedadelhosni Great, do let us know once you have something.

@scalz Thanks buddy . Probably I would have to keep hunting for SPI EEPROMs iguess.

Request, if some one help me with this question. Thanks

@mfalkvidd Thanks for your suggestion. It works great.

I have researched the forum a lot and tried the below, but no success.

• Added 10uF caps to both Node and Gateway. Also tried with 100uF caps.
• Cleared EEPROM.
• Changed Bootloader.
• Changed NRF Radio
• Tried different power source

I have one more node with Relay and its working fine. So i guess the problem should be with the node. The node is a custom built board with Optiboot. I worked fine a couple of times and now I wont work.


Log file for MYSController when I had the MYSBootloader and tried updating FW using OTA. 0_1453856213616_MySensors_20160127-053410.log

I am unable to figure out the problem and seek assistance from the experienced gurus out there.

Appreciate and help I can get.

Can I use i2c EEPROM for OTA bootloading with DualOptiboot or it has to be Serial SPI. I was not able to find any documentation on it. I brought a breakout board and it seems to be i2c, and i2c chips are easily available where I live.

Appreciate your response. Will try gw.process in while loop. I am yet to add the code for endpoint of curtain. I will be using reed switch to detect end and start.

I am using Domoticz as controller. Whats happening is once I press Open, the motor keeps spinning in one direction and on sending command to stop it does not stop. BTW I have L293D to control the motor.

Appreciate any help I can get.

I don't understand your question. If you are talking about the version 1.8.0 showed for java, then yes its Oracle Java.. When you start that's the message you get. You can check with your browser by opening the site, it works fine when I get that message.

What seems to be the problem here.

@n3ro Gr8, makes sense.

@n3ro Why would you need a step up for DHT, I am running DHT11 on 3.3v and it work fine.

On using I had a couple of questions.

• How do I configure more than 1 type of gateway. I have a node which runs using ESP8266 and has DHT11 to read Temp+Hum. Its loaded with EasyESP. Its send data through MQTT. And at the same time Raspi is configured with serial gateway using NRF24L01.

• Add edit option for Timers.

@jkandasa Thanks, Got it working after updating Java 8JDK, which installed JRE1.8

Is there a page that I can request for features or changes, like There is no section which shows me information about the type of gateway configured and if its working or not.

Hi jkandasa,

Amazing job on the MyController. I am trying to install on raspi. Post installation and setting up java, when tried to start. It does not start, below isw the log file.

In Domoticz if you look under settings, there is an button Add Device which works like pairing. There is also a check box to not allow any new device unless you click Add.

Hi,

I am trying to build a node with Ultrasonic sensor and 1 relay. I used the sample code and tried to build one. I am facing issues. The Domoticz will detect the ultrasonic sensor using the provided example code but when I merge them it gives error and does not detect. My sketch is as below:

#include <SPI.h>
#include <MySensor.h>  
#include <NewPing.h>

#define CHILD_ID_DISTANCE 1
#define CHILD_ID_RELAY 10
#define TRIGGER_PIN  6  // Arduino pin tied to trigger pin on the ultrasonic sensor.
#define ECHO_PIN     5  // Arduino pin tied to echo pin on the ultrasonic sensor.
#define MAX_DISTANCE 300 // Maximum distance we want to ping for (in centimeters). Maximum sensor distance is rated at 400-500cm.
#define RELAY_1  3  // Arduino Digital I/O pin number for first relay (second on pin+1 etc)
#define RELAY_ON 1  // GPIO value to write to turn on attached relay
#define RELAY_OFF 0 // GPIO value to write to turn off attached relay

MySensor gw;
NewPing sonar(TRIGGER_PIN, ECHO_PIN, MAX_DISTANCE); // NewPing setup of pins and maximum distance.
MyMessage msg(CHILD_ID_DISTANCE, V_DISTANCE);
int lastDist;
boolean metric = true; 

void setup()  
{ 
  gw.begin(incomingMessage, AUTO,false);

  // Send the sketch version information to the gateway and Controller
  gw.sendSketchInfo("Distance Sensor", "1.0");

  // Register all sensors to gw (they will be created as child devices)
    gw.present(CHILD_ID_DISTANCE, S_DISTANCE);
    boolean metric = gw.getConfig().isMetric;
  
    gw.sendSketchInfo("Relay", "1.0");
    // Register all sensors to gw (they will be created as child devices)
    gw.present(CHILD_ID_RELAY, S_LIGHT);
    // Then set relay pins in output mode
    pinMode(RELAY_1, OUTPUT);   
    // Set relay to last known state (using eeprom storage) 
    digitalWrite(RELAY_1, gw.loadState(CHILD_ID_RELAY)?RELAY_ON:RELAY_OFF);
  
}

void loop()      
{     
	gw.process();

	int dist = metric?sonar.ping_cm():sonar.ping_in();
	Serial.print("Ping: ");
	Serial.print(dist); // Convert ping time to distance in cm and print result (0 = outside set distance range)
	Serial.println(metric?" cm":" in");

	  if (dist != lastDist) {
		  gw.send(msg.set(dist));
		  lastDist = dist;
	  }

  //gw.sleep(SLEEP_TIME);
	
}

void incomingMessage(const MyMessage &message) {
  // We only expect one type of message from controller. But we better check anyway.
  if (message.type==V_LIGHT) {
     // Change relay state
     digitalWrite(RELAY_1, message.getBool()?RELAY_ON:RELAY_OFF);
     // Store state in eeprom
     gw.saveState(message.sensor, message.getBool());
     // Write some debug info
     Serial.print("Incoming change for sensor:");
     Serial.print(message.sensor);
     Serial.print(", New status: ");
     Serial.println(message.getBool());
   } 
}

I am unable to figure out why it is not working.

The log file from Domoticz shows the below:
