During boot, the ENS210 driver reports the following errors:

&lt;p&gt;Sensor startup code runs &lt;em&gt;before&lt;/em&gt; main, and thus runs before power pin is enabled. You can tell by putting a log statement into your powerInit function.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
