Issue with Tuya Humidity Sensor (myd45weu) Data Accuracy

Hi everyone,

I’m experiencing an issue with my Tuya humidity sensor (model: myd45weu). Recently, the graph color changed unexpectedly, and the data has become unreliable, as shown in the attached screenshot.

Previously, the sensor worked fine, but now the data appears inconsistent and useless. I haven’t changed any settings or configurations.

Has anyone else faced similar issues? Do you have any suggestions on troubleshooting or improving the data accuracy of this sensor?

Thank you!

If it is a battery-powered device then be sure to replace the battery with a fresh one, (as the reported power level reading presented by many devices are often not aqurate), and note that power will drain faster if you do not have main-powered Zigbee Router devices close to each battery-powered device. Also check that your device is connected via a Zigbee Router device and not directly to the Zigbee Coordinator →

Regardless of the root cause, before troubleshooting any deeper you should first really take some basic actions to avoid EMI and add more Zigbee Router devices that act as repeaters/extenders so try to follow all the best practice tips in this guide here, as doing so removes many known Zigbee issues:

If that does not work then also recommend upgrade the firmware on your Zigbee Coordinator adapter.

This and more general issues are also covered in ZHA docs troubleshooting section, so read that too:
