Thanks for sharing this. You inspire me and i also made a similar solution during this weekend.

But I have a problem. Maybe you could answer or someone from the forum.
I can not wake up my vacuum (roomba 620) from the state of "suspension" to whose passes automatically after 5 minutes. (all diodes off). Complete code is on end of post.

From old documentation "Roomba_SCI_Spec_Manual.pdf" wake up should looks like this

ser.setRTS (0)
time.sleep (0.1)
ser.setRTS (1)
time.sleep (2)

I can do it "hardware". It means when my yellow cabel from "DD" during insertion into arduino pinMode(D3, OUTPUT) ... roomba weak up all times.

But when cable is connect to D3 permanently and try send few times signals like this.

	digitalWrite(D3, LOW); delay(10); 
	digitalWrite(D3, HIGHT); delay(2);

It didnt work.

Of course it wake up when i push button "clean" by finger. Did you have similar problem

HI !.
@EmielA said:

With this approach you don't need to put anything on top of the Roomba which wil get broken off (is my experience) when its e.g. working under the bench.

I have only 1 dock station and many rooms :). My roomba dont going "under the bench" so i dont have experience like yours with sensor on top.

But will be interested looks for code in your approach so please show it.

Thank You.

Hi !
My bad. I type mistake in post on forum. In code is good version. Of course You have right should be "HIGH"

But You give me some idea on "problem in line D3" . I plugin my logic analizer (Saleae) and bingo!. In my egz. arduino this port was "broken" and dont give any change signal. I plugin into D5 and all works.

I have one small issue / feature. After play song -> (in my code upper this song is Jingle bell for Chrismas) - roomba dont react on buttons. I think i will change this. Also statistic is very bad write. It's also for rewrite.

Now i have to do more test, and next make looking good case for "node" on roomba. (cos mother-in-law - kill me ). But right now im very happy.

Thank you @emka for your replay.

Thanks for sharing this. You inspire me and i also made a similar solution during this weekend.

But I have a problem. Maybe you could answer or someone from the forum.
I can not wake up my vacuum (roomba 620) from the state of "suspension" to whose passes automatically after 5 minutes. (all diodes off). Complete code is on end of post.

From old documentation "Roomba_SCI_Spec_Manual.pdf" wake up should looks like this

ser.setRTS (0)

I can do it "hardware". It means when my yellow cabel from "DD" during insertion into arduino pinMode(D3, OUTPUT) ... roomba weak up all times.

But when cable is connect to D3 permanently and try send few times signals like this.

It didnt work.

Of course it wake up when i push button "clean" by finger. Did you have similar problem

.. after some tests. If Im not wrong only few messages / variables - is support by gw.request() and domoticz.
I used sketch belowe to tests, and i found only supports for:

• S_LIGHT / V_LIGHT
• S_DIMMER / V_DIMMER
• S_BINARY / V_LIGHT
• S_BINARY / V_STATUS

My check list is in this sketch for tests in section comments

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

/*  list of checked types /variables */

/* supported by domoticz and gw.request -> type/variable:
	S_LIGHT / V_LIGHT 
	S_DIMMER / V_DIMMER 
	S_BINARY / V_LIGHT
	S_BINARY / V_STATUS
*/
/* NOT supported by domoticz and gw.request -> type/variable:
	S_DOOR / V_TRIPPED
	S_MOTION / V_TRIPPED
	S_DISTANCE / V_DISTANCE 
	S_TEMP / V_TEMP 
	S_BINARY / V_WATT
	S_HUM / V_HUM
	S_WIND / V_WIND
	S_POWER / V_KWH
*/

Hi !.
Sure next sketch I will use. But the problem looks like it is elsewhere.
I found that if i change in this sketch

• S_DISTANCE -> S_LIGHT
• V_DISTANCE -> V_LIGHT

its works ! Maybe just this type (V_DISTANCE) is not supported in Domoticz and gw.request() (?)

So now I will start a little more test. I'm going to check other types.

Thx for quick answer Hek !.
I comment this line

	//gw.sleep(SEND_FREQUENCY);

upload sketch by still no have log from "V_DISTANCE". Any other idea ?

Hey !
I have a problem with receiving from the controller Domoticz (V2.3799) the V_DISTANCE by gw.request()
MySensors is 1.5 - Latest Release.

I wrote a short test program that shows a problem.

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

#define CHILD_ID 1                              // Id of the sensor child
MySensor gw;
MyMessage msg(CHILD_ID, V_DISTANCE);
MyMessage msg2(CHILD_ID, V_VAR1);
unsigned long SEND_FREQUENCY = 3000;  // 1 sekunda = 1000;

void setup()
{
	gw.begin(incomingMessage);
	gw.sendSketchInfo("Test", "1.1");
	gw.present(CHILD_ID, S_DISTANCE);
}

void loop()
{
	gw.process();
	gw.request(CHILD_ID, V_DISTANCE, 0);
	gw.request(CHILD_ID, V_VAR1, 0);
		delay(2000);
			gw.send(msg.set(0));
		delay(2000);
			gw.send(msg2.set(1));
		delay(2000);
	gw.sleep(SEND_FREQUENCY);
}

void incomingMessage(const MyMessage &message) {
	if (message.type == V_VAR1) {
		Serial.println("Received V_VAR1 from gw ");
	}
	if (message.type == V_DISTANCE) {
	Serial.println("Received V_DISTANCE from gw ");
	}
	Serial.println("incomingMessage");
}

I do not know why I get message for V_VAR1 and didnt get for V_DISTANCE. ?
And short LOG from my node here:

I dont know why i get only message for V_VAR1 and I didnt get for V_DISTANCE. ?
