+title: NEO Coolcam Temperature and Humidity 3in1 Alarm Siren (NAS-AB02W)
+date-published: 2024-12-17
+type: sensor
+standard: global
+board: esp8266
+---
+
+This is a Tuya siren with temperature and humidity sensor. Runs on USB and two CR123A batteries as backup (not supplied with the device).
+Hardware Versions
+
+There are, so far, three known hardware versions. The console will show one of these MCU Product ID’s: {"p":"ymf4oruxqx0xlogp","v":"1.0.0","m":0}, {"p":"ymf4oruxqx0xlogp","v":"1.0.1","m":0} , {"p":"ymf4oruxqx0xlogp","v":"1.0.2","m":0}, {“p”:”ymf4oruxqx0xlogp”,”v”:”1.0.3”,”m”:0} or {"p":"9fngbrgje6ljqhee","v":"1.0.2","m":0}
+
+The ymf versions work with tuya-convert but the 9fn version requires flashing the device with serial.
+
+The 1.0.1 version supports the TuyaSend0 command to query the MCU for the latest values but the 1.0.2 version does not appear to support that command at this time (2021-03-05).
+
+In an order on 2021-01-31 for three devices, one of each hardware versions was received. In an order from 2020-12, the 1.0.1 version was received, which is rock solid.
