<h2><a class="title-link" name="considerations" href="#considerations"></a> Considerations</h2>
<p>If you are using the state of a platform that takes extra time to load, the
Template Sensor may get an <code class="highlighter-rouge">unknown</code> state during startup. This results
in error messages in your log file until that platform has completed loading.
If you use <code class="highlighter-rouge">is_state()</code> function in your template, you can avoid this situation.
Template Sensor may get an <code class="highlighter-rouge">unknown</code> state during startup. To avoid this (and the resulting
error messages in your log file), you can use <code class="highlighter-rouge">is_state()</code> function in your template.
For example, you would replace
<code class="highlighter-rouge"><span class="p">{</span><span class="err">{</span><span class="w"> </span><span class="err">states.switch.source.state</span><span class="w"> </span><span class="err">==</span><span class="w"> </span><span class="err">'on'</span><span class="w"> </span><span class="p">}</span><span class="err">}</span></code>
with this equivalent that returns <code class="highlighter-rouge">true</code>/<code class="highlighter-rouge">false</code> and never gives an unknown
with this equivalent that returns <code class="highlighter-rouge">true</code>/<code class="highlighter-rouge">false</code> and never gives an <code class="highlighter-rouge">unknown</code>
result:
<code class="highlighter-rouge"><span class="p">{</span><span class="err">{</span><span class="w"> </span><span class="err">is_state('switch.source',</span><span class="w"> </span><span class="err">'on')</span><span class="w"> </span><span class="p">}</span><span class="err">}</span></code></p>
