<h2 id="recording"><span class="enumerate-headings-plugin enumerate-heading-plugin">1.2</span> Recording</h2>
<p>To record real images of a meter, you have to periodically fetch <code>http://&lt;IP&gt;/img_tmp/raw.jpg</code>.</p>
<p>To automate this, you can use the following shell script (Linux only):</p>
<pre><code class="language-bash">#!/bin/bash
while [[ true ]]; do
echo "fetching value..."
wget -q http://192.168.1.151/value -O value.txt
value=`cat value.txt`
echo "Value: $value"
diff=`diff value.txt value_previous.txt`
changed=$?
#echo "Diff: $diff"
if [[ $changed -ne 0 ]]; then
echo "Value changed:"
echo $diff
echo "fetching image..."
wget -q http://192.168.1.151/img_tmp/raw.jpg -O $value.jpg
else
echo "Value did not change, skipping image fetching!"
fi
cp value.txt value_previous.txt
echo "waiting 60s..."
sleep 60
