Heatpump Control with Souliss

[Alex]

Hi,

I did a short introduction this week.

I promised i will give you some more details of the project which i am trying to solve with souliss.

Target:

I wanted to control my heat pump with my mobile phone. For the heat pump i used µC2 SE controller from carel.

On the heat pump controller i can define 2 inputs. One for switching the heat pump ON/OFF and one input to switch between two predefined set points. 

Maybe on a later stage adding some temperature measurements to display the actual state. But this feature is nice to have ;-)

My current way to the solution:

I did a look into my tinker box.

• Old Android phone
• Raspberry Pi
• Arduino Duemilanove + ethernet shield
• Wlan Router 
• Ethernet Hub

With this equipment I started the proof of concept phase on the bench ;-) 

To get a easy access from Internet to the android phone i used yaler.net web access. Which i installed on the raspi as described. Only thing i had to change is adding the port :8080 to the ./run script.

As web interface I use openhab i also installed it on the raspberry pi. So far so good. This page on your wiki helped me a lot to get the openhab side working.

Last step was souliss side which was very easy because i used the "Souliss_ex01_HelloWorld". Removed the input and added an additional output and the added also the openhab api. 

Currently planed improvements:

Use instead the Arduino a Olimexino 32u4 with mod-wifi. Because i don't want to wire a Ethernet cable. 

Olimexino is already here but at the moment i am getting some errors during the compile. 

Move from the bench testing to the real world into my heat pump control box.

This was a short introduction details will follow.

Alex

[Alex]

As i wrote above i tried to compile the same code for a olimexino 32u4 board and I getting some errors.

Only thing i changed was the Hardware setting from 0x04 to 0x0b. After that i am getting errors.

I am doing something which is not supported?

As i wrote on my introduction i am not the hardcore C hacker :-) maybe someone can help me.

regards

Alex

Hi Alex,

Is a simple bug, a wrong folder addressed in the files contained into the files in frame/vNet/drivers/ethMRF24/

Look to the files as the one in the below link
http://code.google.com/p/souliss/source/browse/Souliss/frame/vNet/drivers/ethMRF24/vNetDriver_eth.cpp

Is looking for files in folder wifiMRF24 instead of ethMRF24, just change the folder name and it should work.
If you can please open an "issue" so I will not forget to fix it for the next release.

I will read also your other post and give an answer,
Dario.

Thanks for your fast answer !

I will test it tomorrow. I will try to open an issue.

[Alex]

Issue is created.

I renamed it at vNetDriver_eth.cpp and vNetDriver_eth.h but i still get a compile error:

In file included from C:\Users\Alex\Documents\Arduino\libraries\souliss/frame/vNet/vNet.cpp:49,

[Di Maio, Dario]

In file vNetDriver_eth.cpp line 175 change with this:
  if(!uip_udp_sock((u16_t*)ip_addr, vNet_port, (u16_t)ETH_PORT))
   

Then, for now comment the openHAB APIs then we will include it back.

Let me know,

Compile works without error i will upload it to the board tomorrow and test if it works with the souliss app.

I will also enter an additional issue. Now i need some sleep ;-)

Alex

[Di Maio, Dario]

That's nice.

Please consider that the openHAB interface over uIP (ENC and MRF24) is still under testing.

Juan did some test that was successful with the ENC, but actually there is no support for MRF. It should not be a problem adding it, but I cannot guarantee that will work.

As you can see in the wiki, only Wiznet based devices has actually official support for openHAB.
So you will be the tester for it.

Regards,
Dario.

More, for other reasons I need a picture of the label on top of your wifi module.

I need to understand the production date and firware used because updates was claimed to be incompatible.

[Alex]

Hi,

I did not know that the module is not supported at the moment. I should read the wiki pages to the end ;-)

My project is not that urgent to waste your time.
But if you wanna spend the time i will for sure play the tester role.

As soon as i get home i send you the picture.

Alex

[Di Maio, Dario]

I'm not saying that isn't supported, but that isn't officially.

Actually on uIP (the software IP stack used with ENC and MRF24) the code looks working, is just a matter of few includes.

Once we get it compiling and working, we will move on openHAB side.

Nice. I ordered this one 2 weeks ago so they have some old ones on stock. Maybe I should order some more ;-)

I am checking the Olimexino board and i saw some strange behavior at the supply voltage on the UEXT connector.

Now I am reading through the manual and saw that the supply can be switched with D8. I have to get familiar with those boards.

Till now i used only original Arduinos..

As soon i know the details i will try to test module. 

[Di Maio, Dario]

Details?

Details of the olimexino board and UEXT connector. Because I have some problems there.

As I wrote yesterday the compile worked. I did download the code to the olimexino which is runing with the 3,3V setting.

But nothing happened so i began to check the supply voltage on the UEXT connector and it looks like this:

(No module on the UEXT connector)

With connected module the voltage is around 400mV. Which is not very good for a stable run of the wlan module ;-)

That's the reason I want to read the documentation again to understand how the UEXT connector should work.

[Di Maio, Dario]

There is a drawback with UEXT, that isn't standard, some pins may change from host to host. Use a flat cable and broke non used pins, in your case you just need SPI and power.
As example, the I2C and USART on board side can be interrupt on MODWIFI side.

I got them working quickly, hope will be the same for you.

It works now after a little hardware hardware hack ;-)

I did open the FET3_E jumper (red circle) and connected r21 direct to GND (red arrow). Now I have supply on the module and it works with the souliss app.

But a software solution should also work. Set D8 as output and to LOW. 

I tested it with WiFi_OpenNetwork, WiFi_WPA and WiFi_WPA2 and Souliss APP

[Di Maio, Dario]

Mmmmh... Yep!

Some UEXT modules has external power supply and feed the board through UEXT, so this way let you select if you want or not this.

I've done most of test with an Olimex T32U4 that hasn't this feature, but last time with Olimexino didn't give me any supply problem. Probably I've that jumper open.

So now is time to move to openHAB :) go into Souliss.h file and include the MRF24 define as per ENC one otherwise your code will never be loaded.

Don't enable PEESISTANCE as first shot, otherwise you will run out of RAM. That mode is available only on Mega or with a lowered maximum number of nodes and slots.

Let me know if you succed,
Dario.

[Alex]

Hi

Thank's for your tips

I am not sure if i did understand you.

So what i did was adding a OR to the include of the ENC with the WIFI_MRF24. 

So for example:

#elif((OPENHAB == 1) && (VNET_MEDIA1_ENABLE && (ETH_ENC28J60 || WIFI_MRF24)))

# include "interfaces/openHAB_HTTP_uIP.cpp"

#endif 

If this is complete "bullshit" please forgive me. 

Nevertheless i tried to compile it. But now i have to less program space on the AVR.

Binary sketch size: 30,670 bytes (of a 28,672 byte maximum)

Alex 

[Di Maio, Dario]

Is it, but the MRF24 drivers looks too big to fit into the Atmega328. You need to move to a bigger microcontroller :(

You can't use this hardware for openHAB.

I used a 32U4 but i think same problem because both have only 32k of flash.

Which controller with more memory is a good option for souliss?

Would it be a solution to use my arduino+W5100 shield as gateway (openhab handling) and the olimexino+mod-wifi (io handling) as my node for the switching on heatpump side.

[Di Maio, Dario]

Yes, use an Atmega2560 (Mega) as gateway you will no longer mind about RAM and FLASH.

I have now a working solution without a mega ;-)

Using a Arduino board with w5100 shield as Gateway node. This one does the Openhab handling and Gateway functions.

On the 2nd node i use the Olimexino 32U4 with mod-wifi for the relay switching.

Thanks Dario for the support. I like the souliss project more and more.

I guess that you have reduced the number of nodes and slot. Is it?

I am using the W5100.

I will give you some feedback. 

The Range was not that bad ~12 Meters in the building (two walls in between).

Now i add the node to openhab so i can do some switching cycles through the week. To get a feeling how stable it works.

Alex

[Alex]

Nrf24 runs since 1 week without any problems. Also the control over openhab runs very stable. Nice work.

Is it possible to use a pin interrupt and one timer on the node. Or are the resources already used from souliss? Node with souliss and configured with Nrf24 interface.

Alex

[Di Maio, Dario]

For which scope?

Are you running with W5100 or ENC?

Only nrf24 nothing else because w5100 is on the gateway which does also the bridge to the nrf side.

I have installed DALI at my home and i thought maybe i can use souliss to transfer the 2 bytes of data.

Flavio you are right. It's a manchester coded serial signal.

Did some first quick and dirty tests ;-)

timer0 is used by arduino for millis() function.

Did some tests with timer1 seems not to be used.

After that i did some concept testing without timer function and it looks good so far.

Tomorrow i will test it as souliss node and do some tests if NRF24 is still working.

Alex

[Di Maio, Dario]

Which is the scope? Running the nRF over interrupt? Probably is yet in that way, but I'm not sure at 100%.
The Atmega radio driver is interrupt driven.

Actually there are some methods to runs a battery-friendly Souliss node, letting him sleep till an interrupt, but has never been tested.

Dario.

On the scope you can see a dali forward frame. Currently I am not using the interrupt i used the standard delay microsecond function to generate the signal. That's why i said quick and dirty ;-) Also I am currently try to learn C so i am limited to handle things. But i am getting better. 

The nRF and the souliss framework is still standard on the node. I will test it tomorrow if it still works but it should..

Which Atmega radio driver? 

Currently this runs on a 32u4 with one nRF and using one digital output for the dali tx.

Which kind of interrupt do you use to wake it up?

regards

Alex

[Di Maio, Dario]

The radio on Chibiduino module, gives an interrupt to notify the micro.
