Smoke Detector 3 in 1 Smoke, Temperature, Humidity not bringing in all the values

Configuration
1

I have purchased 4x new smoke alarms Tuya Wifi Smoke Alarm Temperature And Humidity Detection 3 In1 Fire Protection Smoke Detector Sensor Smart Life Firefighter - Smoke Detector - AliExpress and hoping to get some control in Home Assistant. All required functionality works in the Smart Home/Tuya app however when I import the device in Home assistant it only shows that it is a smoke detector.

When I view the devices in google home it comes through correctly.

Ideally I would like the ability to turn off the alarms and view the temperature and humidity within home assistant.

Can somebody please steer me in the right direction.

Thanks!

I have tried to edit sensors.py myself, but I’m probably doing something incorrectly as the entities are not added in Home Assistant

Also, I would like to mention, I got here, when I have opened Feature request topic here: Tuya Smoke sensor with temperature and humidity So if you still have the problem, please vote for it.
