i have tried making the MPR talk to arduino, but i could not find the right library for your code.. what lib are you using? the adafruit one just spews out errors..

yes there is indeed something in the source code there.. but it is only the setpoint almost like a thermostat.

in my code i presented three values. two of these values where not recognised as could be seen in the last post. but the last value was indeed a temperature setting and was recognised as a thermostat.

i guess i will post this to domoticz and hopefully it will be implemented :D

Thanks you guys for the help!

i will post back here if i find anything usefull or when it is working just so others can find it.

@mfalkvidd thanks for the tip! i got the following result in domoticz.

16-08-29 11:22:34.763 (mysensor) Temp (Baro Temp)
2016-08-29 11:22:34.772 (mysensor) General/Barometer (Baro)

2016-08-29 11:22:35.298 (mysensor) Temp (Baro Temp)

this is what i get when presenting 3 values back to domoticz.
i guess this means that V_HVAC_FLOW_STATE and V_HVAC_SPEED are not implemented in domoticz yet?
is there a way for me to work around this?

is there anyone that has the switch for HVAC working in domoticz?

i have tried several times to create a HVAC switch by presenting my node with " present(CHILD_ID_HVAC, S_HVAC);"
but when i look in domoticz there is no node to be found in the devices or in the hardware( under setup), only in the log i can see that the node has presented itself correctly.

is it possible that S_HVAC is not supported by domoticz? is there a workaround for this?

thanks for the help anyway!

count me in!
i'll be happy putting in some effort to help MYSController!

arduino pro mini + nRF24L01+ @ 3.5v

you can search for MYScontroller on the forum, you'll find this post regarding OTA updates with MYScontroller.

it involves flashing a new bootloader, but it is totally worth it once you upload new code to a node embedded in a wall or something.

@tekka
Awesome! everything now works like a charm! many thanks for your help!

i tried using the OTA FW update by following your guide a few posts up and i must say i like it a lot!
i just cant figure out how to upload FW from the software. every time it starts uploading FW by responding on FW requests my gateway seems to freeze, i use a usb ttl converter and arduino pro mini with radio as gw. i also uploaded the log. by the time the server responds to the FW req i have assigned FW to the node. then the GW just stops recieving and transmitting for no apearent reason so there is no communication back and forth, then when i reset the GW ( by pushing the reset button on the GW the comm is back up.. when the GW is frosen the led (pin 13, clock) is also completely off.. and yes, i also tried a radio with capacitor.

ahw, I realy like the ui of EasyIoT.
isn't there any other way I can feed it serial data? it doesn't necessarily have to be so easy, but if I could just get it to accept my data I would be verrrry happy :)

I can imagine there is a function requesting data from some sort of library that handles communication with the RF24 through the GPIO ports. but can I not feed the serial data directly to the requesting function? sure, I like it a lot that the GPIO pins get used for the radio, but unafortunatly I do not own a raspberry.

@EasyIoT In the description of EasyIoT it says that it also works on the windows platform.
I can get the server running on a windows machine but i can not seem to get it connected to my serial gateway. i have a usb interface with arduino nano and a rf24 module but i can not find the setting in EasyIoT to use COM14.

is there anyone with the same problem?

@Dirk_H
I use LiFe batteries in my battery sensors. they are a bit oversized, but they work just fine.
And because of the lower operating voltage I don´t need any type of voltage regulation :+1:

@epierre
as a battery operated solution I use li-fe battery's they have a lower voltage per cell then lion and lipo so there is no need for any type of voltage regulation witch makes it simple. I just need to watch out not to over discharge the battery, but with 3Ah on a temp/hum sensor that will not be much of a problem ;)

OT:
seems like a very interesting board with lots of function and usefull stuff. But for $25 I would mutch rather throw my own hardware on a breadboard or protoboard or something.

@tbowmo
The relays are 12VDC so the arduino can not be wired directly to the relay. the arduino should power a shift register, transistor, FET, or other semiconductor (and not pulling any more than 40mA.) and therefore indirectly controlling the 12v flow to the relay.

I think it is wise to use optocouplers if you would want to protect the 5v circuitry against the 12v rail, but everyone should chose for themselves since the extra cost and hassle for optoisolators may not weigh up to the cost of the 5v circuit.
all that happens when you accidentally apply 12v to your arduino is that it may smell a bit and it will never work again, witch is a quick fix with a new nano. Opto-isolation is more effective when working with 110 - 220v and when working in humid environments i.e. shower or bathroom.

if you are going to be on the cheap side and use relays without a breakout board and/or set up your own relayboard then please pay attention to the flyback diode you should have across the coil of your relay. it prevents flyback voltage from building up and damaging your fet/transistor/shiftregister. ( even though it might not fail on the first time you try it without flyback, it will eventually and finding the problem is quite a pain)

wow, this is something!
would really love to set this up at home!
i also can't wait for your link to appear, really exited !

Never had a roomba, but i have obtained remote control of my automatic LG vacuum :+1:
I just copied the IR remote commands and transmit them on command from a sensor node.
There is no feedback, but i don't think i need feedback, when the battery is empty it drives back to the docking station. All i can say is that just pushing start remotely and getting home to a clean house is nice ;)

bump

I also wonder what the S, T, PT & L values stand for..
i see them coming and going but never understood what they are here for ;)

happy new year!

@daulagari

i installed DomotiGa with a git command as described on the installation page. so i guess i have th latest version.

Eventhough i did execute the command sucessfully and the response was that i am already a member of the group i think something must have gone wrong is this step. i wouldnt know how to check or redo/undo whatever this step.
"
$ sudo addgroup domo dialout
"

thanks!

hello @hek ,

i have installed the domotiga server on my ubuntu machine but i can not seem to get the usb connection working :(
when i start domotiga i can configure the mysensors interface according to the installation guide, but i can not open the serial connection ..

this is all i got .. what am i doing wrong?
2014/11/20 23:03:12 [Plugin] MySensors, Instance #1 enabled.

hey,

i really feel like i'm just nagging about things here.. sorry about that.
i can not seem to get the sensor to listen to the serial output from the plugin..
i suspect the plugin from not transmitting a newline, every string transmitted should end with \n

thanks :)

Thanks @tbowmo !
I uploaded two standard sketches to the node and the gateway so i never noticed before.
It seems quite logical to define the child-sensor-ID in the sketches on the sensor node itself.
will do that next time i upload a new sketch!
