# COMFORT / VIVID Technical Reference Manual
There are several releases of the COMFORT/VIVID sensor (formerly known as Home Sensor, Smart Room Sensor). The Technical Reference Manuals (TRM) applicable to each revision are provided in the table found below.
1. COMFORT refers to the base model.
2. VIVID refers to the PIR model.
Before selecting a TRM, you will have to identify your model and revision of the COMFORT/VIVID sensor.
### Model Identification
Please see the above picture for identifying the following:
1. T-code
2. Revision
3. Serial number
### Firmware Version
Some TRMs correspond to specific firmware versions of the COMFORT/VIVID sensor. To determine this, you will need to send the following downlink to the sensor:
1. Hex: 0x71
2. Port: 100
When the sensor responds, the **first 3 bytes** determine what the firmware version of the device is.
### Table of Technical Reference Manuals
Once the T-Code and revision has been identified, please match it according to the table below for your specific TRM.
