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

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?
