Hi,
On the Raspberry pi I'm running Debian 8 “Jessie”
It returs the kernel info:
# uname -a
Linux hc-wv-rapi3 4.1.17-v7+ #838 SMP Tue Feb 9 13:15:09 GMT 2016 armv7l
GNU/Linux
I've checked my blacklist
# cat /etc/modprobe.d/owfs-common.conf
blacklist ds9490r
blacklist ds2490
blacklist wire
The loaded kernel modules:
# lsmod

At the moment I concentrate me on the owserver.
The owhttpd server return only the “Apache2 Debian Default Page”?
Other defined apache2 sites are working fine.

Checking the running processes with
# ps -ef | grep ow
I see only the owserver
The owget works:
# owget /10.0C95B7000800/temperature 7
# owget /1D.CAB804000000/counter.A 3335256
This for all 7 temperature sensors and the 2 DS2423 cards.
I wrote a small php script to read the sensors & counters
<?php
require "/usr/share/php/OWNet/ownet.php";
$ow = new OWNet("tcp://127.0.0.1:4304"); #default location, verbose errors,
Celsius degrees
$owadds = $ow->dir('/')['data_php'];
$owaddresses = explode(",", str_replace('/', '', $owadds));
$ow10temperatures = array(); // DS1820 - 1-Wire temperatursensor
$ow1DdualCounters = array(); // DS2423 - 1-Wire Dual Counter
foreach ($owaddresses as $owaddress) {
$fam = substr($owaddress, 0, 2);
switch ($fam) {
case '10':
$ow10temperatures[] = $owaddress;
break;
case '1D':
$ow1DdualCounters[] = $owaddress;
break;
default:
break;
}
}
$return_full_info_array = TRUE;
$parse_php_type = TRUE;
foreach ($ow1DdualCounters as $owaddress) {
$ca = $ow->get("/" . $owaddress . "/counter.A", OWNET_MSG_READ,
$return_full_info_array, $parse_php_type);
echo "Counter A " . $owaddress . " = " . $ca['data'] . "\n";
$cb = $ow->get("/" . $owaddress . "/counter.B", OWNET_MSG_READ,
$return_full_info_array, $parse_php_type);
echo "Counter B " . $owaddress . " = " . $cb['data'] . "\n";
}
foreach ($ow10temperatures as $owaddress) {
$tg = $ow->get("/" . $owaddress . "/temperature", OWNET_MSG_READ,
$return_full_info_array, $parse_php_type);
echo "owt->get returned: ".print_r($tg, TRUE)."\n";
echo "Temperature sensor = '" . $owaddress . "' = " . $tg['data'] . ' ' .
$tg['unit'] . "\n";
}
This returns:
# php ownet-test.php
Counter A 1D.CAB804000000 = 3335256
Counter B 1D.CAB804000000 = 10985886
Counter A 1D.53BE04000000 = 10060396
Counter B 1D.53BE04000000 = 1024
owt->get returned: Array
(
[0] => 0
[1] => 12
[2] => 12
[3] => 258

[data_len] => 12
[data_php] => 6.875

)
Temperature sensor = '10.0C95B7000800' = 6.875 C
owt->get returned:
Temperature sensor = '10.4282B7000800' =
owt->get returned:
Temperature sensor = '10.B284B7000800' =
owt->get returned:
Temperature sensor = '10.D6ADC4000800' =
owt->get returned:
Temperature sensor = '10.61B9C4000800' =
owt->get returned:
Temperature sensor = '10.832409000800' =
owt->get returned:
Temperature sensor = '10.6F90B7000800' =
If I check the owserver running in a separate console I see that all the
temperatures are read but are not transferred to the php script! Only the
first one.
Here some cut-outs from the owserver debug lines:
DEBUG: ow_read.c:(620) Read /10.6F90B7000800/temperature Extension 0
Gives result 0

…
All reading of the sensor & counters generate a lot of owserver debug
information which I don't understand.
I hope this info will be enough so someone can help my further.
Kind regards,
Willy
