Image for raspberry Pi ?

Just install Debian or Ubuntu, install python 2.x from the repositories and copy the software over, install it and it should work. I don't see a differnce between a normal PC and the Raspberry Pi. You just need an USB-to-Serial converter as I believe the raspberry Pi does not have a serial interface, but I can be wrong on that point.

Thanks Robert Penz, that solved my question.

I have a Debian Wheezy image on the raspberry pi.
And I install (apt-get install phyton2.6) and install:
apt-get install python-serial python-rrdtool python-rrd python-setuptools rrdtool

But the package "pyrrd.rrb" are unable to install.
It is an the Image also python2.7 and python 3.
Please can you help me?

do you have the error message? did you search Internet for the error message. if the error occurs during installing a Debian package you need to contact the Debian guys.

This question was expired because it remained in the 'Needs information' state without activity for the last 15 days.

Hello Steffen,

any news? Have been able to solve this? I had the same Idear for my Tecalor

Thanks Jens

Hello Jens,
no I haven't solve the problem.
I would like to install a gentoo in the raspberry pi.
So i can emerge the package.

But if you have a Image for the sd card, please inform me.
Tanks.

Start the software as root.

Sorry I can not test at the thz403.
Because we have them delivered until next year.
Is it so ok?

You need to get root privileges .. As long as you have $ at prompt that's not the case.

HI Steffen,
Hi Robert,

my THZ403 is already running.
I have been able to start the heatpumpMonitor.py
But I~M not sure how I get a connection via my USB-RS232 adapter. Hardware is described very well from Robert. No Problem wit h that. But:

I'm quite new with Debian and of cause Unix .. it took me a while to get it running .. same as you did now.

Could my someone help me with the USB-RS232 adapter please?
A hint where I can get informations from would be ok for me ..

Thanks Jens

That's an other question, so please create a new entry

What's the error message now?

ok same on my Raspi ..
so try to start the webbrowser and use
http://localhost

Sorry Jens,
but when the applications heatpumpMonitor.py don't have a pid, I thing the application crashed after start?
I don't have a Display at the raspberry pi. I'm per SSH on the console.
So I don't can test it on the browser.
Please Robert help us.
BR Steffen

When the raspberry boot.
You Must Login as pi and Passwort.
The you must be Root --> sudo su
Please waite 1 Minute.

Now are the pid 2385 startend.
BR Steffen

If you don't have the pid @ ps aux
please Type:
heatpumpMonitor.py restart
It is a problem of the raspberry and the ftdi Chip.
BR Steffen

@Steffen,

Of cause you are right! I Need to have the process running to See a Chart.

I Used your description and finally I got it running a minute ago.

Finally I only got it running after really plug the Raspi with my Tecalor heatpump.
Thanks for you help on this. I did learn a lot during try to get it running.

Thanks BR Jens

How long does it take on a raspi to render the images?

HI Robert,
how do we count this? Have you add a counter somewhere in your scripts, which we need to change? Or do you just need a 'feeling' value?
Thanks
Jens

Meanwhile it works on my RasPi too. Rendering all images was not always managed within a minute, so sometimes I got warning messages in the log file. I changed the setup a bit (added humidity, no. of errors, graphs for 6 hours, 2 days, 3 days, error table, log file, error help section to the browser UI, switched to german lnguage, ...), and during these actions I removed the small graphs completely. This saves enough time to almost never reach the 60 seconds border. Meanwhile I additionally copy all data to a web server every 15 minutes, and still rendering works within 60 seconds always.
Next plan is to avoid rendering unnecessarily: e.g.in case of yearly view it's enough to build the png's once per day. This will give me enough free ressources to monitor my photovoltaic energy with RasPi as well.
