Tuya T&H Sensor (001TH0202_CB3S / tdq) – no entities/unsupported, anyone solved?

Third party integrations

Hi all,

I’m having trouble getting my Tuya T&H Sensor to work with Home Assistant.
Model: 001TH0202_CB3S (category tdq)
Device ID: bf5521e446909f2407tq7q
Setup:

  • Sensor is online and working in the Smart Life/Tuya app
  • Integrated with both Tuya Cloud and LocalTuya (via HACS)
  • Local Key, Device ID, and LAN IP set up (device IP: 192.168.1.26)
  • Tried all protocol versions (3.1, 3.2, 3.3, 3.4)
  • Added manual DPS (1-8), tried changing scan interval
  • Home Assistant version: 2026.1.1 on HAOS

Problem:
The device is recognized, but no entities are exposed in Home Assistant. The UI shows “unsupported”, and the diagnostic JSON has function, status_range, and status as empty objects ({}). See below for snippet:

Code

"function": {},
"status_range": {},
"status": {},
"entities": []

LocalTuya also returns an unknown error and doesn’t show any DP values.

Is anyone using this model (001TH0202_CB3S) or category (tdq) and managed to get temperature/humidity entities in HA?
Are there any workarounds, alternate firmware, or tweaks for making this device show up with entities, either via Tuya or LocalTuya?

Any help or suggestions would be very appreciated—thanks!

there are multiple issues on github for tuya on this category. Check them out on how things get resolved. (or get off the tuya train and save you headaches and time)

This happens to me too with the 001TH0202_CB3S devices.
Do you mean “get off the train” with Tuya or with the type of sensors?

Tuya , you will see on this forum that tuya is just hard to manage with all this quirks. Find a brand that has bit more consistency, for your own good
