Hello,

This weekend I've been busy with a prototype for a touch wall switch.
So far is going pretty well and everything seems to work.
I still need to integrate it with MySensors, but I hope this will be the easiest part.
The only problem I found is with the sensitivity of the touch sensors when connected to external power.
It works perfectly when using USB power, but not quite right then using AC power.

Here's how it looks so far. Remember this is just a proof of concept and many things where just do as I go and probably will be a better way to do it.

Any suggestions / comments will be greatly appreciated.

This is the front plate made with a 2mm methacrylate plastic, with a printed paper behind.

This is the back side with the touch controller

And this is the actual node with the led driver and the buzzer

And this is how it works for now

Hello,

I always wanted a motion sensor that could also detect light levels.
Until now I used two sensors attached to one arduino to achieve that, but now I make a hardware combination that works and also looks more discreet.

This is the device I used as a base, adding the light sensor.

First of all I removed the white dome.
Then a little adjustment was needed becasue the light sensor is too long so the sensor chip fits properly inside the dome.

Also the white plastic needed some cutting to allow the circuit to enter the dome.

The light sensor circuit has to be on the opposite side of this little metal pit in order to fit properly.

Here is the assembly almos done, with the light sensing chip facing up inside the dome.

Little hotglue on the corners to hold it toghether

And that's all to it.

Here's the code. Just a simple combine of the 2 sensors.

#include <MySensor.h>  
#include <SPI.h>
#include <BH1750.h>
#include <Wire.h> 

#define CHILD_ID_LIGHT 0
#define LIGHT_SENSOR_ANALOG_PIN 0
unsigned long SLEEP_TIME = 30000; // Sleep time between reads (in milliseconds)

#define DIGITAL_INPUT_SENSOR 3   // The digital input you attached your motion sensor.  (Only 2 and 3 generates interrupt!)
#define INTERRUPT DIGITAL_INPUT_SENSOR-2 // Usually the interrupt = pin -2 (on uno/nano anyway)
#define CHILD_ID 1   // Id of the sensor child

BH1750 lightSensor;

MySensor gw;
// Initialize motion message
MyMessage msg(CHILD_ID, V_TRIPPED);
MyMessage msg2(CHILD_ID_LIGHT, V_LIGHT_LEVEL);
uint16_t lastlux;

void setup()  
{  
  gw.begin();

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

  pinMode(DIGITAL_INPUT_SENSOR, INPUT);      // sets the motion sensor digital pin as input

  // Register all sensors to gw (they will be created as child devices)
  gw.present(CHILD_ID, S_MOTION);
  gw.present(CHILD_ID_LIGHT, S_LIGHT_LEVEL);

  lightSensor.begin();
}

void loop()     
{     
  // Read digital motion value
  boolean tripped = digitalRead(DIGITAL_INPUT_SENSOR) == HIGH; 
    
  Serial.println(tripped);
  gw.send(msg.set(tripped?"1":"0"));  // Send tripped value to gw 

  uint16_t lux = lightSensor.readLightLevel();// Get Lux value
  Serial.println(lux);
  if (lux != lastlux) {
      gw.send(msg2.set(lux));
      lastlux = lux;
  }


  // Sleep until interrupt comes in on motion sensor. Send update every two minute. 
  gw.sleep(INTERRUPT,CHANGE, SLEEP_TIME);
}

This is a rough integration of the code with MySensors.
It sends messages back and forth, so if a button is touched it turns on the corresponding device on the controller and if the switch is turned on the controller, the touch leds are updated accordingly

Here is my first attemp at it.
I just started with eagle, so maybe there is room for improvement.
This is for a dimmer node, with some connector for motion detector and light sensor.
It has an onboard 7805 regulator and a mosfet to PWM the leds.

Comments are welcome

I got it finally installed.
This is what it looks like.

I'm working on a pcb smaller version. I'll keep you posted.

Hello,

It's been a while since a posted last. It's been really busy around here.

I've been using a node with a button to start and stop nap time, and control some scene.

My controller has been Vera for a long time, but now I think it's time for an upgrade.
I installed openhab a few weeks back and started to play with it.

Anyway, I thought it was time to make a new thing to control naps. That's how nap machine was born. But as I was building it, I thought it could do a lot more. Become a grown up scene controller.

As you can see in the video, it has an oled display, a rotary encoder and a buzzer.
It works with SPI displays, as well as I2C. It also has a radio to connect with MySensors gateway.
The rotary encoder has a integrated button and 2 leds. The program can detect rotation, single click, double click and long click.

Take a look at the video to see some options. Still in early stage, but it works and it's fully integrated with MySensors.
I need now to integrate it with openhab, and in this regard I hope to find some help here.

Feel free to comment or suggest new uses.
In the following days I'll post the code as it is now, and some schematics for those interested.

@BulldogLowell
I'm using 74HC595.
I solved it changing the sketch from relay to servo, and them making some modifications to it.
It works very nice now.

Hello,

I have a node that every once in a while just stops responding.
I have to unplug it to get it back working.
It is strange because it doesn't appear to be a reason.
Anyone had issues like this before?

@Atman
Yes it is all hand made.
Next step would be to make a board to make it smaller and easier to make

@hek
Here's a basic implementation of the sending queue I came up with.

First I modified this functions:

function sendCommandWithMessageType(altid, messageType, ack, variableId, value)

	local cmd = altid..";".. msgType[messageType] .. ";" .. ack .. ";" .. variableId .. ";" .. value

	-- only add to list if of SET type
	if (messageType =="SET") then
		addToMyQueue(cmd)
 	end

	if (luup.io.write(cmd) == false)  then
		task("Cannot send command - communications error", TASK_ERROR)
		luup.set_failure(true)
		return false
	end

	return true
end

function processIncoming(s)
	local incomingData = s:split(";")
	if (#incomingData >=4) then
		-- check if msg is in the list to remove it
		checkMyQueue(s);

		local nodeId = incomingData[1]

...

end

And added this other functions:

-- adds cmd msg to the list before sending
function addToMyQueue(myCmd)

	local isFound = inTable(MyMsgs, myCmd);
	-- if not already in the list, add it
	if (isFound == false) then
		table.insert( MyMsgs, myCmd )
	end
	
end

-- check if msg is in the list to remove it
function checkMyQueue(msg)
	log(MyPrefix .. ">T> queue        : " .. printTable(MyMsgs) )
	local isFound = inTable(MyMsgs, msg);
	-- if msg found, remove it because has been executed
	if (isFound ~= false) then
		log("msg found in pos: "..isFound..". Removing from list...")
		table.remove (MyMsgs , isFound) 
		else

			log("msg not found in list") 
		end
	log(MyPrefix .. ">T> queue updated: " .. printTable(MyMsgs) )
end

function inTable(tbl, item)
    for key, value in pairs(tbl) do
        if value == item then return key end
    end
    return false
end

It basically works but the problem with this is that processIncoming() is only processed when a new message arrives, so there is no way we could re-send lost messages when iddle.

We need a function that could be executed at regular intervals to check if there are any messages left in the queue to be re-send.

Thank you.
I'll make some tests if I can find one

Hello,
Here's a simple schematic of the project

Thank you.
I'll keep trying some other things..

yes.. more or less the same

Hello,

I had a similar problem some time ago..
Take a look at this to see if it might help

https://forum.mysensors.org/topic/131/scene-too-fast-for-gateway

Tried all sorts of things.
Also tried the module with antenna and the one without..
The problem is random.

When it happens, I see the node sending data, and I see the gateway receiving it realtime, but the do not connect.
That's what I don't understand.

I just draw them in photoshop, save then as monochrome gif, and then use an online service to generate the arrays to use on the code.

Something like this:

Hello,
I created an MQTT gateway a few days ago and a node to check communication.
I'm on 2.1.1 and everything seems to work fine most of the time.

But sometimes, when powering up the node, I get lots of fail massages.

The gateway receives messages from the node, but for some reason the don't understand each other.

I tried the log parser but I don't see where is the problem.

I'd appreciate any help.
Thanks in advance

Hello,

It's been a while since a posted last. It's been really busy around here.

I've been using a node with a button to start and stop nap time, and control some scene.

My controller has been Vera for a long time, but now I think it's time for an upgrade.
I installed openhab a few weeks back and started to play with it.

Anyway, I thought it was time to make a new thing to control naps. That's how nap machine was born. But as I was building it, I thought it could do a lot more. Become a grown up scene controller.

As you can see in the video, it has an oled display, a rotary encoder and a buzzer.
It works with SPI displays, as well as I2C. It also has a radio to connect with MySensors gateway.
The rotary encoder has a integrated button and 2 leds. The program can detect rotation, single click, double click and long click.

Take a look at the video to see some options. Still in early stage, but it works and it's fully integrated with MySensors.
I need now to integrate it with openhab, and in this regard I hope to find some help here.

Feel free to comment or suggest new uses.
In the following days I'll post the code as it is now, and some schematics for those interested.

Hello,

This <MyBuffer.h> is not really needed if you don't want to check if message is received on the node.

Just remove that line and everything should work.
