Meteobridge RPI: fixes a bug that prevents from re-installing the Dashboard.

The reason I ask is the folowing:

I write a new sdcard today with the .bin file downloaded to my ubuntu 22LTS computer and use Raspberrypi imager to do so.
after starting up everything works fine exept for the dashbord.

I write a new sdcard on the same computer with dd.
after starting it up ...

echo data20 $(printf "%0.0f" $(echo "$volt*100"|bc))"\n"data21 $(printf "%0.0f" $(echo "$amp*100"|bc))"\n"data22 $(printf "%0.0f" $(echo "$watt*100"|bc))"\n"data23 $(printf "%0.0f" $(echo "$wattH*100"|bc));

that is, IF you have "bc" installed.

GNU grep 2.6.3

So, different grep, sorry
I have a working script here on debian squeeze, with multiplication included, but it seems I can't help you because the differences in our systems.
Just in case someone wants to try: #! /bin/sh
#
while :
do
WhatWeRead=$(grep -m 1 V /dev/ttyUSB0)

# Format ...

did find another way using grep:
-m 1 :stop after 1 match
and we know there is allways a "V" in the string

#! /bin/sh
#
while :
do
WhatWeRead=$(grep -m 1 V /dev/ttyUSB0)

# Format reading
volt=`echo $WhatWeRead | cut -c -7`
amp=`echo $WhatWeRead | cut -c 10-16`
watt=`echo $WhatWeRead | cut -c 19 ...

Note: I tested the script using a file, are you sure cat is not hanging when you use it with /dev/ttyUSB0 from within the script ?
I have never done that.
you can see what shellscripts are doing when you use and start it manually

This should do it if:
When you do a cat /dev/ttyUSB0
the result is:00016.3V-00013.4A 00218.2W 00557.5WH

#! /bin/sh
#
while :
do

# Read data from sensors
WhatWeRead=`cat /dev/ttyUSB0`

# Format reading
volt=`echo $WhatWeRead | cut -c -7`
amp=`echo $WhatWeRead | cut -c 10-16`
watt=`echo $WhatWeRead ...

The best I can really do so far is (from SSH):
cat /dev/ttyUSB0
(or ttyUSB1) will output:
00016.3V-00013.4A 00218.2W 00557.5WH


#! /bin/sh
#
while :
do

# Read data from sensors
WhatWeRead=`cat /dev/ttyUSB0`

# Format reading
volt=`echo $WhatWeRead | cut -c -7`

echo data20 $(printf "%0.1f ...

I have two questions:
First how the crontab to do? (where he edited, how)
Second as the graph created by upload via FTP to other graphs?
:!: Are you sure you want to try this ?
You can brake your system and nobody can fix it for you.

Using cron is one of the basics in Linux, so I don't know it ...

You can try this

Hello,

installing the latest updates I hoped for the indication of memory wear but memory wear indication does not work on my NSLU2.

I get the following error messages in my system log:

/home/meteohub/wear.sh: /home/meteohub/wear.sh: 38: Syntax error: +
cat: /sys/block/s: No such file or ...

Great job, like always.

See it in action ? I'm using it.

Thank you Boris, it sure will help Ken to build a nice template for the meteohub system

I've got my Sheeva Meteohub now uploading to a local FTP service.. now to figure out how to insert a custom template for the MHtags file on the Meteohub.

Best regards,
Ken
Had to move the function to put the data in array to the defs-file.
Meteohub seems to replace everything between [ and ] and ...
