<ul class="simple">
<li><p>Calibrate the device in the web interface</p></li>
<li><p>Check the angle/tilt. If the device is reporting 90 degress then its not going into sleep. Tilt the device and check if sleep works.</p></li>
<li><p>Check in reported voltage of the battery in the web interface. If this is higher than 4.15V the device belives its beeing charged. In that case adjust the voltage factor under hardware so the voltage drops below 4.15V.</p></li>
<li><p>Check if the <cite>always on</cite> option is activated in the web interface.</p></li>

<h2>Calibration error (unable to find a valid formula)<a class="headerlink" href="#calibration-error-unable-to-find-a-valid-formula" title="Permalink to this headline">#</a></h2>
<p>If you have issues to get a calibration formula. When a formula has been created the device always tries to validate the formula against the supplied values and if there is a to high deviation on any of the values then the formula will be rejected.</p>
<p>The image here shows such a case, one of the values is out of bounds.</p>
<a class="reference internal image-reference" href="_images/qa_1.png"><img alt="Calibration Error" src="_images/qa_1.png" style="width: 500px;"/></a>
<p>To fix these this you can;</p>
<ul class="simple">
<li><p>remove the value from the list (setting the angle to zero will do that)</p></li>
<li><p>change the advanced setting (Formula max deviation) to a higher value and save the values again.</p></li>
</ul>
<p>In the case above this paramater was changed from 1.6 SG to 4 SG and the formula was accepted. The deviation on this point was just above 3 SG.</p>
