[solved] Using Domoticz with many LAN raspberry and DS18B20

[PeM1664]

Hi everybody, I'm a newbie with Domotics and I'm using it for recording temperature issue coming from DS18B20 1-wire sensors.
I've put one or more sensors in each raspberry I have in my house (more than 5) and I'm wondering if I can regroup all the measurement in one Domoticz window?
All the raspberry are in the same network and I've tried to locate them with a Domotics windows in my Ubuntu server but I didn't find the way to do this.. On All Raspb I've installed Domotics but I have to open 1 windows by raspb for have one measurement and 1 log of it..
Is it possible to use only one interface of Domoticz for capture the measurement of different raspb by ssh?
tks for yours answers

Check the manual and look for domoticz remote server.

I found it! Thanks

Hi all I re-send... why can"t I see the GPIO ports declared in 1 domoticz web server (and I can see and control them) threw/via a global server using raspberry remote server control config( witch is working very well for temp)?

I found it! just have to action the switch in domoticz remote server to update in domoticz primary

Hi,

Installing Domoticz on all client is a bit overkill.

I solved like this:

temp.sh

Code: Select all

TEMP=$(cat /sys/bus/w1/devices/28-00000463dd89/w1_slave | grep  -E -o ".{0,0}t=.{0,5}" | cut -c 3-)
VAR=$(echo "scale=2; $TEMP/1000" | bc)
curl --connect-timeout 60 "http://192.168.1.54:8080/json.htm?type=command&param=udevice&idx=51&nvalue=0&svalue=$VAR"

And you can run every 5min with cron.

I'm trying to implement this script but it does not show me the temperature.
Sensor updates but nothing else
Sensor ID and IDX from Domoticz I have inserted correctly
Maybe some error in the script is

Uh, I am not using this anymore, but I am trying to help.

What is the output of:

Code: Select all

TEMP=$(cat /sys/bus/w1/devices/28-00000463dd89/w1_slave | grep  -E -o ".{0,0}t=.{0,5}" | cut -c 3-)
echo $TEMP
VAR=$(echo "scale=2; $TEMP/1000" | bc)
echo $VAR
curl --connect-timeout 60 "http://192.168.1.54:8080/json.htm?type=command&param=udevice&idx=51&nvalue=0&svalue=$VAR"

Unfortunately it does not work

temp.jpg (64.11 KiB) Viewed 3400 times

It only works if I manually make each line separately

temp2.jpg (83.72 KiB) Viewed 3398 times

When you add 1.3 at the end of the line ";" works but the console reports errors

temp3.jpg (68.46 KiB) Viewed 3395 times

Code: Select all

TEMP=$(cat /sys/bus/w1/devices/28-031552e458ff/w1_slave | grep -E -o ".{0,0}t=.{0,5}" | cut -c 3-);
echo $TEMP
VAR=$(echo "scale=2; $TEMP/1000" | bc);
echo $VAR
curl --connect-timeout 60 "http://192.168.1.100:8078/json.htm?type=command&param=udevice&idx=59&nvalue=0&svalue=$VAR"

Everything works.
It helped:

Code: Select all

Resolved with Notepad++ :
1) Menu->Edit->EOL Conversion -> Unix/OSX Format
2) Then Save
Fixed

Can you write how to add script to cron every 5 minutes?

[pvm]

'crontab -e' there's a description in the file which shows up then.

Everything works great.
Thanks a lot!
