Hi.

I'm having a problem getting cm160 to run on my Raspberry Pi.

When I plug in the Owl I see it appear in /var/log/syslog and a device for it appears at /dev/ttyUSB0.

However, when I run ./cm160, I get this output, with the "No error" message on the first pass and the "could not detach kernel driver..." message from then on.

# ./cm160 
Wait for cm160 device to be connected
Found compatible device #0: 0fde:ca05 (002)
Found 1 compatible device
bulk_read returned -110 (No error)
Wait for cm160 device to be connected
Found compatible device #0: 0fde:ca05 (002)
Found 1 compatible device
bulk_read returned -110 (could not detach kernel driver from interface 0: No data available)
Wait for cm160 device to be connected
Found compatible device #0: 0fde:ca05 (002)
Found 1 compatible device

If I tail /var/log/syslog, I get this the second I run ./cm160

May 28 20:49:31 pi-zero-w kernel: [1043641.132661] cp210x ttyUSB0: cp210x converter now disconnected from ttyUSB0
May 28 20:49:31 pi-zero-w kernel: [1043641.132802] cp210x 1-1:1.0: device disconnected

At this point, /dev/ttyUSB0 no longer exists. If I do the following it reappears until I run ./cm160 again:
rmmod cp210x && modprobe cp210x

So, my uneducated guess is that running cm160 is instantly upsetting the cp210x module.

I've tried building cm160 myself and have tried jesjimher/eagle-owl fork, which explicitly mentions running it on a Raspberry Pi. I've tried two different Owl units, and three different Pi's, all with the same result.

Any help would be appreciated. I bought this Owl specifically to monitor via a Pi and I've hit a bit of a dead-end.

Cheers.

I am running the cm160 binary in a non demon mode like: ./cm160 just to check the data coming in. If I terminate this, and try to restart it, I get the following:

zoell@srv02:~/eagle-owl/src$ sudo ./cm160
Wait for cm160 device to be connected
Found compatible device #0: 0fde:ca05 (036)
Found 1 compatible device
bulk_read returned -110 (could not detach kernel driver from interface 0: No data available)
Wait for cm160 device to be connected
Found compatible device #0: 0fde:ca05 (036)
Found 1 compatible device

And it does not do anything just retries these. The only solution I could find is to unplug/plug the usb, but this is a bit pain if I am not at home. Is there any idea on this?

Hi, just a little info in case someone runs across the same problem I did...

I set this up on a Mint 17 (Ubuntu 14.04) based machine, and was able to see the live data via live.php ok but there was no historic/stats data available.

I assumed that this would normally be derived from the stats_db (which appeared to be updated correctly - file size was growing, and mod times were recent), and displayed via index.php. However when I accessed index.php it displayed nothing, and there was no error message.

Further searching in the logs revealed a server error (PHP Fatal error: Class 'SQLite3' not found...). To fix this:

apt-get install php5-sqlite

Then restart apache - the latter is important because the initial restart following installation of sqlite didn't sort it out. After this it worked fine.

Cheers.

Hi guys,
Being trying this incredible project today, on RPi 3B+, and RPi4, with the most recent OS, and an old Jessie just in case, all the time I get the next:

And nothing new come to the application, which remains to wait for hours:

You have the fclose on the .live file inside of the check data integrity if statement. This means that you slowly build up a load of open files every time there is a data issue. This continues into the OS file limit is reached and then the program stops being able to write data to the SQL db. Move the fclose outside of the if statement and all should be fixed.

Hello,

when I launch the daemon I got:

data error: invalid ID 0x29
0x29 - 0x49 - 0x44 - 0x54 - 0x43 - 0x4d - 0x56 - 0x30 - 0x30 - 0x31 - 0x01 -

Any clue about the reason is not working?

Thanks a lot

Reno.

Hi,

Since one month and a half the cm160 process display :

But on the LCD screen the month is well set to March.
Any idea ?

Hello,

I tried the application and encountered a few hickups:
-I got some data at year 2555 ?!? which I thought should not occur has this is an issue that has been flagged and solved.
-The application suddenly crashed.

I wonder Is there a way to have logs when it is daemonized ?
I am not a programmer so I have no real clue. I suppose that it is in daemonize.c where stdout & stderr are redirected to /dev/null but I am not sure.

Hi there,

Thankyou for writing this software. After running it for a few hours I've started getting the following output:

0xff - 0xff - 0xff - 0xff - 0xff - 0xff - 0xff - 0xff - 0xff - 0x50 - 0x59 -

Restarting the cm160 binary fixes it. Any ideas or how I could go about debugging further ?

Thanks,

After I upgraded the system to Ubuntu 15.x, the data collection from the device is no longer working.
I think that it is not an issue with your software but with the usb link, however my knowledge of Linux is to limited to find the error.
attached some clipping from Syslog, where I disconnected and reconnected the usb cable, and then restarted the cm160 program, and they are no longer talking to each other.
(sorry no attachment, I can't upload a txt file, so... see below)
Worked perfectly under 14.x.

I would appreciate if you could put me on the right track to fix it.

Best regards,

Luc

OWL CM160 have 3 sensors (for triphased current).
Right now we can read only the main sensor but maybe it is possible to read both 2 ou 3 sensors ?

I've tried to figure out myself how to do that, and I think maybe it's in the rec->addr field ?

Hello!

Sometimes I got these wrong readings from daemon, despite validity check I see in sources.
Killing and restarting daemon helps, just need to cleanup sqlitedb afterwards.

How can I help in troubleshooting this?

Hi,

Any idea?

Hi,

Firstly it's a great utility, really useful thank you.

However, powertop shows it wakes the CPU 800 times per second when running as a daemon. This adds 3w to the draw of the system, or put another way increases my electricity bill for that server by about 5%.

Can you fix this wake issue?

Thanks,
Niall

Hi, OWL has worked for two weeks smoothly, but today stopped working suddenly. What I have is dmesg flooded with entries like the following:

Device seems to work after restart of cm160 process, but I have numerous Nautilus popup on Unity that tell me I can't mount MTP device ... I don't know what I have to do in order to stop these popups appeared today, I think something is changed with the last Ubuntu kernel?

Any help would be appreciated,
thanks!

It seems the OWL has a temperature sensor on board, I'm wondering if I could get that from the received data.

I've looked through the code and can spot the bit where a frame is decoded but I can't seem to find any information regarding the size of the frame and therefore any other potential data that might be along side the electricity data.

(I still have to look through your code)

Could it be possible that the live info is referred to 230V even if I set 220V in the Owl receiver?
I'm reading (now) 257W on the .live file while the LCD display on the Owl is showing 246W.
The ratio is very similar to 220/230V...

How to get back the data by python or other one and to send them in influxdb (grafana) ?

Hello!

Daemon writes live reading to .live file - 16/02/2016 15:35 - 177.10 kW
Power output is wrong, should be 0.177 kW

when selecting one full year, I got "JSChart: Input data in wrong format for selected chart type" and other follwing errors in separate dialog boxes

I'll investigate (if I can, I don't know javascript)

substitute "source" with "." and it works

my .live file sometimes gets filled with data such as:

255/01/2255 255:255 - 724.50 kW

did it happen to you also?

I hope it's the last one, I'm testing and I'm reporting my findings to improve your software ;)
