Description

Device normal info

  • Shenzhen Zhenniu Innovation
  • Model: ZN-MT29

Device info (please complete the following information, which can be found in log):

I'm sorry, but the log was removed and now I don't know where can I find requested information.

In few words, there's no information about CO, TVOC and PM1.0 data in homeassistant. In Tuya app I can see all this values.

Contributor guide

Research direction
Trace the data point (DP) mapping for the ZN MT29 device in the integration's device profiles. Check the Tuya API response for all available DP IDs and compare with the mapping in tuya home assistant. Ensure CO, TVOC, and PM1.0 DPs are correctly registered and exposed as sensors.
