I think you should have a raspberrypi folder at

/usr/share/emoncms/www/Modules/raspberrypi

and rather than a cron entry  it's started with this file

/etc/init.d/rfm12piphp

at start up or using

sudo service rfm12piphp restart log

during installation

Do you have those files ?

Paul

I've just checked and yes I do :

pi@raspberrypi /usr/share/emoncms/www/Modules/raspberrypi $ ls -al

well that's a good start, i would try commenting out the cron line, reboot and see if raspberrypi_run.php is running

sudo ps -ef | grep raspberrypi_run.php

it should be running if it isn't try 

sudo service rfm12piphp restart log

and check again.

I have noticed some anomalies with my install while looking at this and as I've been doing some experimenting, I'm not sure on what is correct. I will do a fresh install later this evening to check some odd file locations I've discovered.

Paul

I took the cron entry out and did the reboot. Here's the result of:

sudo ps -ef | grep raspberrypi_run.php

root      2811     1 89 15:08 pts/0    00:11:17 /usr/bin/php -f /usr/share/emonc
ms/www/Modules/raspberrypi/raspberrypi_run.php
pi        2854  2778  0 15:20 pts/0    00:00:00 grep --color=auto raspberrypi_ru
n.php

Looks like it is running. Not sure why grep came back with two entries.

Terry

One is just the command you ran to find the command, which isn't itself excluded from the search :-)

If you run the restart command with "log" on the end as above, it should leave a log file in /var/log. On my system I can tail that log and watch the packets arrive - that should tell you if the problem is before or after the rfm12pi software interface?

This is what I'm getting:

pi@raspberrypi /var/log $ sudo tail rfm12piphp.log
00,18,07,00s
00,18,07,00s
00,18,07,00s
00,18,07,00s
00,18,07,00s
00,18,07,00s
00,18,07,00s
00,18,07,00s
00,18,08,00s
00,18,08,00s

Doesn't look right. From memory my transmitting nodes are on 10, 19, 20 and 21.

Terry

No that doesn't look like its receiving, how frequent are these packets showing in the log? if every 5sec's maybe it's the time being transmitted for emonGLCD unless you have disabled it.

Did you edit /boot/cmdline.txt (requires reboot if edited) you should have 

dwc_otg.lpm_enable=0 console=tty1 root=/dev/sda2 rootfstype=ext4 elevator=deadline rootwait

(sda2 may differ the rest should be the same) and edit /etc/inittab to allow raspberrypi module access to the serial port by commenting out the last line so it reads

# T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100

I think it may be the latter that's causing the issue, it wasn't commented out on my system and as I'm not using rfm12pi I wouldn't of known. (restart rfm with sudo service rfm12piphp restart log if edited)

Paul

Hi

Changed /boot/cmdline and /etc/inittab and that fixed it.

Thanks for taking the time to sort this out for me - you're a good man. Hopefully I'll be able to return the favor sometime.

Next step is to let the software run for sometime to test whether the lock ups I experienced before updating the RFM12Pi software have stopped . Then I'll start trying to get the multi zone stuff working that's being developed.

Thanks again for your help - much appreciated.

Terry 

No problem only too pleased to help.

Regards the "locking up" have you tried updating the rfm2pi firmware? I believe the new firmware was updated to target that complaint in particular.

Paul 

Yes I have updated the RFM12Pi firmware using these instructions from theRFM12Pi v2 hardware pages. I have an SD card based on Raspbian and nothing else solely to let me do the updates to the RFM12Pi.

$ sudo apt-get update
$ sudo apt-get install arduino
$ sudo apt-get install python-dev&&python-rpi.gpio
$ git clone https://github.com/mharizanov/avrdude-rpi.git
$ cd avrdude-rpi
$ sudo cp autoreset /usr/bin
$ sudo cp avrdude-autoreset /usr/bin
$ sudo mv /usr/bin/avrdude /usr/bin/avrdude-original
$ sudo ln -s /usr/bin/avrdude-autoreset /usr/bin/avrdude
$ cd /home/pi
$ git clone https://github.com/mharizanov/RFM2Pi.git
$ cd RFM2Pi/firmware/RF12_Demo_atmega328
$ sudo service rfm12piphp stop
$ avrdude -v  -c arduino -p ATMEGA328P -P /dev/ttyAMA0 -b 38400 -U flash:w:RF12_Demo_atmega328.cpp.hex
$ sudo service rfm12piphp start

I'm assuming this will give me the latest version which should help with the lock ups.
