A very beginner needs help - MySensors and OpenHab !

ewgor

I have tested your example (above) and its not working. After i deleted all in the hashmap in the rule file, i can say its not refreshing the values on the localhost but i still can see them in the server monitor:
This is how it shows if i have only the temp and hum in the hashmap:

2015-07-22 19:58:11.891 [INFO ] [runtime.busevents             ] - livingTemp01
state updated to 33.0
Temp item: livingTemp01 temp: 33.0

If i add another address in the hashmap like this:

"101;18;"            -> "livingKwh18",  // CHILD_ID_KWH == 18 changed in the sketch too!
"livingKwh18"        -> "101;18;",

the local host is freezing but the server is still updating the values only that this time in a different way:

2015-07-22 20:08:53.140 [INFO ] [runtime.busevents             ] - Arduino state
 updated to 0;0;3;0;9;read: 101-101-0 s=3,c=1,t=0,pt=7,l=5:33.0
101;3;1;0;0;33.0

As for the Kwh i see something in the server side which i suppose is the Kwh value (don't have the CT sensor connected yet) but it doesn't appear in the localhost!
This is what it shows and i suppose the last value 0,6 is the value read on Arduino analog pin A0:

2015-07-22 20:12:38.319 [INFO ] [runtime.busevents             ] - Arduino state
 updated to 0;0;3;0;9;read: 101-101-0 s=17,c=1,t=17,pt=7,l=5:607246.3
101;17;1;0;17;607246.3
0;0;3;0;9;read: 101-101-0 s=18,c=1,t=18,pt=7,l=5:0.6
101;18;1;0;18;0.6

Regarding the two switches, they are still dead after i added the items you gave me in the items file and i get this error on the server when i switch on /off any of them but it seems its still sending the command:

2015-07-22 20:46:43.839 [INFO ] [runtime.busevents             ] - lightKitchenC

2015-07-22 20:46:58.925 [INFO ] [runtime.busevents             ] - Arduino state

which i suppose is related to the sitemap, items and the rule files and here i still can work until i lose the errors but the problem is (i think !) in the Arduino sketch because i dont think they match with that code I have right now from you, speaking about the same sketch you posted here http://forum.mysensors.org/topic/655/serial-gateway-connection-to-openhab/3.
Any chance to make it work? :(:cry: :weary:

TimO

Remove the "item=kLights" that makes no sense and produces the error you posted.

{
  Frame label="Dormitor" {
    Text item=livingTemp01
    Text item=livingHum01
    Text item=livingKwh01
  }
   Frame label="Lights" {
        Group label="Lights" {
            Switch item=lightBar01 label="Bar Lights"
            Switch item=lightKitchenCabinet01 label="Cabinet Lights"
        }
    }

The update of the Temperature looks good, can't figure out, why the value is not shown in on the webpage.

Here is my output :

Temp item: workTemp01 temp: 25.4
2015-07-22 21:53:14.902 [INFO ] [runtime.busevents             ] - workTemp01 state updated to 25.4

Did you refresh the webpage (silly question I know)?

Regarding the switches:

rule "lightBar04 Switch Rule"
    when
        Item lightBar04 changed
    then
        switchOperation.apply(lightBar04, Arduino, sensorToItemsMap.get("lightBar04"), V_LIGHT)         
end

Change that to:

rule "Light"
        when
                Item lightBar01 received update
        then
               if(receivedCommand == ON) {
            sendCommand(Arduino, "101;1;1;0;2;1\n")
        }
        if(receivedCommand == OFF) {
           sendCommand(Arduino, "101;1;1;0;2;0\n")
        }
end

Let's see what works now. ;-)

Hi TimO,
There is no chance to make it work. The server is ok, receive info from both sides, from web switches (ok now with that stupid klight removed) and from sensors too one by one (it can be seeing by addresses: s0, s3, s4, s5) but the webpage (on localhost) is frozen, cant understand why!
Could you please test this files on your pc? bellow are the files modified according to your indications:
Openhab items, rules, sitemap:

About the sensors, if i add another address in the hashmap other than temp and hum the web freezes, if i leave only the temp and hum, the web page can be refreshed and will display the temp and hum values. In the mean time my server receive info as i said previously from both sides (webpage and sensors) but is not sending them forward.
have anyone made it with relay with button actuators and openhab? the task would be to switch on/off the relay from webpage and button and to get the status on the web page even if the relay is operated from that physical button.

About the CT sensor, in the server monitor i get this msg:

2015-07-24 13:34:09.614 [WARN ] [.model.script.actions.BusEvent] - Item 'null' does not exist.
Watt item: null watt: 621372.3 2015-07-24 13:34:13.805 [WARN ] [.model.script.actions.BusEvent] - Item 'null' does not exist. Kwh item: null kwh: 0.6

I guess this "null" is because i didnt connect yet the CT sensor? Can anyone who have exp. with this kind of sensor help me? my Openhab config are above.
Thanks for any help.

With this rule:

rule "Light"
        when
                Item lightBar01 received update
        then
               if(receivedCommand == ON) {
            sendCommand(Arduino, "101;1;1;0;2;1\n")
        }
        if(receivedCommand == OFF) {
           sendCommand(Arduino, "101;1;1;0;2;0\n")
        }
end

i get this error:

2015-07-24 17:40:02.994 [INFO ] [runtime.busevents             ] - lightBar01 received command ON
2015-07-24 17:40:03.020 [ERROR] [o.o.c.s.ScriptExecutionThread ] - Error during the execution of rule 'Light': The name 'receivedCommand' cannot be resolved toan item or type.

i cant believe that there are 1.7k users here, more than 1k online, more than 500 views (including mine (maybe half them :)) and nobody helps :eyes:

Help please.

ewgor

can anyone try my example above and tell me if it is working or not? speaking to hero members, not to those as me! Common people, please help us, we are not stealing your jobs or future, we just want to light a simple led on/off!
thanks to all intelligent people here :P

People might not have run into the same problems as you're having you know. And the amount of community members running OpenHab+MQTT isn't that huge I guess. So even if many here would like to help you we don't have the time or possibility to re-create your environment.

A good approach to isolate the problem (shaving off as much as much irrelevant stuff as possible). You know that the wireless communication is working... so something must be wrong in the rules or you've found some kind of bug in OpenHab.

You don't need CTs to test sending in a value from the Arduino.. Just set and send any value using the API to test it. Mocking is a good approach when testing.

ewgor

@hek thanks for your replay! i'm not using OpenHab+MQTT but the serial gateway communication explained by @TimO and i got the errors shown above so my questions are point by point. i tried different ways to see if i can get loose of the errors but no chance and than i came here asking for help.
My idea was if somebody have the needed time to test my config (opehab + arduino) and to tell me if is working on their pc or not and maybe some instructions where or what needs to be changed, modified deleted or added.
I count on experienced people who can see quikly where is the mistake and who could give me useful information as for example @TimO did at one point.

Once again, besides hum and temp that works at this hour i need to add a few buttons who could turn a light on/of from openhab and from physiscal buttons too and to understand why if i add a new device as CT sensor its not displaying anymore the rest of the devices.
Thanks for understanding.

TimO

Hi @ewgor ,

could you make your whole configuration available for download? It is easier for us to help you to find the error.

ewgor

@TimO what do you mean by " configuration available for download"? i'm combining different Arduino sketches found here on the site and i'm trying to find a way to match them with the Openhab configuration found here too! All my files are above but right now i'm trying to combine the Arduino sketch from above with this one for relay with button actuator from here http://www.mysensors.org/build/relay and its very difficult. couldn't do it today, maybe tomorrow :(
As a conclusion because i don't know if i was very clear: Could anyone help me combine Arduino sketch from above with the one for relay with button actuator for 2 (two relays and two buttons) devices and to check the Openhab config which are above too? As i already said, today o tried all day long to combine them but cant lose the errors, it cant compile :(

Hoping for an answer ...

The physical button is connected to digital pin 3 and a LED to digital pin 4.

but the LED is not switching on or off.
On the other hand when pressing the physical button on / off the LED is working but the switch in Openhab is not moving or refreshing.

i'm trying to take it easy! please help masters :)

Update:
i noticed that if i leave only the light Openhab config as bellow, when pressing the physical button on my breadboard it turns the led on or off and it changes the Openhab switch state from on to off and vice-versa but it doesn't work from Openhab to Arduino.

If i delete the rule "light" (the last part of rule file) the server doesn't show the error and the server still works so pressing the physical button it turns on or off the LED and it change the Openhab switch from on to off but from Openhab to Arduino, the same, still not communicating, not turning any LED!
This is how the server looks if i delete the rule "light" and i press the physical button on my breadboard:

and switching from Openhab but without changing the LED real state:

This makes sens and the problem i know is on the rule file. Now is there anyone who can help me make this work from Openhab to Arduino too? thanks all for your kindness :)

PS: using the Arduino relay with button actuator sketch on which i added the node id 101 and the pins 48,49 for my Arduino mega.

No body? Any idea?

TimO

Found it!

"received command" not "received update"!

rule "Light"
        when
                Item lightBar01 received command
        then
               if(receivedCommand == ON) {
            sendCommand(Arduino, "101;1;1;0;2;1\n")
        }
        if(receivedCommand == OFF) {
           sendCommand(Arduino, "101;1;1;0;2;0\n")
        }
end

Hi,
@TimO finally I managed to add the dht 11 too and it works fine. Can you please tell me what to change in the rule file to add more buttons (same as this one that works)? I tried to change some parts of the light address but it doesn't work.
I would like to add a normal button too (not like a switch) with a door symbol like door open or close for my exit door and to change its status from blue to red when you push the button.

Thank you for the help you gave me by now!
All the best!

Hi All,

Can anyone please tell me if I want to add a few more buttons (same as this one with relay with button actuator) what should i change in the Openhab rules and in the Arduino sketch too? can it be done as the relay actuator example ?

#define RELAY_1  3  // Arduino Digital I/O pin number for first relay (second on pin+1 etc)

i mean first relay is connected to pin 3 and the next relay to pin 3+1=4, pin 4+1=5 and so on and the buttons pins to be alocated in the same way? is there any way to do it like this but for the relay with button actuator example?

In the Openhab rules i tried to modify as i said above some of the addresses of the commands on or off from here:

sendCommand(Arduino, "101;1;1;0;2;1\n")

except the last numbers which i understand are like 1 for ON and 0 for OFF but it didn't work.

The last thing that i would like to add is related only to Openhab if ill get an answer or a suggestion to my ask here above is a normal button (not like a slider) to control an electrical strike through a relay so when pressed once door open for 5 seconds or more and than close again. I know that here are more to discuss because maybe the door its not gonna be psychically closed but the Openhab status could show that the door is closed but this can be solved with a magnetic contact (i think) that can be added so the Openhab rules should be made like so: if the magnetic contact is connected than the door is closed and locked, else the door is open / unlocked even the electrical strike is closed until the magnetic contact will be connected! or to close the electrical strike only after the magnetic contact is closed.
OH too much talking, I know this is maybe too much for me but theoretical speaking I know how to make it and I think i know how to set up the connection but physically is impossible because of missing knowledge in programming Arduino or Openhab!

Lets take it one by one: Can anyone help me with first part of my request, how to add a few more buttons same as the only one working now?

Thanks all

People i see that this post was seen by more than 2k times but nobody is answering! How is this possible? Nobody knows how to do it or everybody enjoy watching a noob asking for help? Common people at least off topic let's say hi each other!

A very beginner needs help - MySensors and OpenHab !
