But by reading the data sheet carefully, we discover an operating temperature limited to 0-40 \u00b0C. In other words, it measures up to -20 \u00b0C, but no longer works below 0 \u00b0C.

This sensor is rare in France and difficult to find at a reasonable price. I ended up ordering it on Amazon at \u20ac27.45 (the price went up to \u20ac28.42 two days after my order, and there were only 11 left in stock).<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Reception_et_premiere_impression\"><\/span>Reception and first impression<span class=\"ez-toc-section-end\"><\/span><\/h2>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">Ordered on November 8, the package arrived on November 14, despite a public holiday.

A push of the reset button (using the tool provided) finally triggers the pairing mode. Zigbee2MQTT immediately detects the sensor, which is displayed under the name <strong>TS0201<\/strong>.
