Pimatic 0.9 .. is more stable , but unfortunately needs CPU power .

---

Hi, Pimatic 0.9 … running really much more stable than the old version , but unfortunately needs CPU power . I have not had a crash for almost a month . A few plugins are still missing , but the main run . In others, I can wait .
But I would like to know why my CPU utilization permanently located at about 50 % since switching to pimatic 0.9 ? Previously I had an average of 15- 20 % .

Furthermore, I can not get more than 24 hours the statistics . No matter what I choose , the result is always a 24 hour view .

Have you tried to restart the computer pimatic is running on? My raspberry has a CPU load of below 1% with pimatic running permanently. Several weeks ago npm or nodejs had a hickup. Can’t remember whether I killed the task or gave it a reboot. Anyway, CPU load dropped from 50% to 3%.

Also I wanted an arduino to handle the 433MHz communcation. Without an arduino but homeduino plugin ready to receive data, CPU rises to 16%.

Did you copy your old database? Otherwise it may take some time to collect the data again.

pimatic restart several times . Unfortunately, without a lower CPU utilization , thereafter . What strikes me is that my Wifi module flashes continuously . He has 0.9 … not done before switching on Pimatic . Not in this short frequency .

strange! my cpu load on a p3 is constantly at 9 to 10 % what i find relatively high, but this is due to the high query rate for my various iframe, shellsensor and variables devices

what pi do you use? and did you update an existing system or install from scratch?
what does the command top say? do you have any other services running that constantly generate high loads?

you can also install htop which has a nicer gui with sudo apt-get install htop

you can see that when pimatic is “working” the cpu rates are rising immediately but then go back to a low level again.

By the looks of your setups my Rpi3 is just idling at 3-8%…I think it is time to expand my system…

I like to use Htop, but for more information about what is using your system atop looks like a candidate… more info here.

Hello , I use the Raspberry B + without overclocking. The system I have reinstalled . So empty SD card, then Jessy , then pimatic , …
Besides pimatic runs only monit on the Raspberry . And so as I see it consuming node has a large amount of CPU power .

It is possible that the short interval to a device, the CPU load so ?
I use in a device a interval of 500.

Alright, on a B+ you could expect more load due to less CPU power. After reinstallation, did you let the system ‘set’ for a couple of hours?
I found that after altering my config.josn (adding in all the devices and plugins) the system needed some time to install.

@Stokstaart
What do you mean by system ‘set’ ?
I first installed Jessie , then pimatic immediately.

The system runs now already over a month . And despite the CPU problems , very stable

@Thrusty said in Pimatic 0.9 .. is more stable , but unfortunately needs CPU power .:

The system runs now already over a month . And despite the CPU problems , very stable

okay, then disregard my previous post. You really should get to identify the program that i hogging your CPU…

btw are you using Homeduino? (and is it in combination with an Arduino or are u using the Rpi directly??)

@Stokstaart
Yes I use Homeduino with an Arduino Nano . My output from top , htop you can see above . Atop this to say to me:

I fear there are too short Intervale some devices .
I had a device provided to test something on 50. Had it then unfortunately forgot . Another stood on 500.
Now that is one to 5000 and the other in 1000. As the CPU utilization is now looks lower.

@Thrusty Which version of NodeJS do you have installed? Make sure your installed version is 4.4.5, 4.4.6 or 4.4.7 (LTS). I remember some eralier 4.x versions had performance issues. Another source for “load” may be debugging (make sure you have debug turned of with pimatic and plugins) and database logging. About the latter I am not sure whether or not the defaults for DB logging have changed. We may review this at a later stage.

As other users have reported here the load on my pimatic 0.9 setup (homedunio, unipi, edimax, shell-execute, opeweather, johnny-five, sysinfo, filter, dewpoint) is below 1% on the average.

@mwittig I have installed these versions:

pi@rasppitest:~ $ node -v
v4.4.5
pi@rasppitest:~ $ nodejs -v
v0.10.29

But where can I debugging leave everything for pimatic and plugins ?
In the config I have this :

"messageLogging": [
        {
          "level": "*",
          "tags": [],
          "expire": "7d"
        },
        {
          "level": "debug",
          "tags": [],
          "expire": "0"
        }
      ]

And this:

{
      "plugin": "homeduino",
      "driver": "serialport",
      "driverOptions": {
        "serialDevice": "/dev/ttyUSB0",
        "baudrate": 115200
      },
      "receiverPin": 0,
      "transmitterPin": 4,
      "dstSearchAddressPin": 12,
      "debug": false,
      "active": true
    },
