TSL2561 - stodev-com-br/tasmota GitHub Wiki
This feature is included only in tasmota-sensors.bin
Otherwise you must compile your build. Add the following to user_config_override.h:
#ifndef USE_VEML6070
#define USE_TSL2561 // Enable TSL2561 sensor (I2C address 0x29, 0x39 or 0x49) (+2k3 code)
#endif
The TSL2561 luminosity sensor is an advanced digital light I2C sensor, ideal for use in a wide range of light situations.
| TSL2561 | ESP8266 |
|---|---|
| GND | GND |
| VCC | 3.3V |
| SCL | GPIOy |
| SDA | GPIOx |
| INT | not used |
In the Configuration -> Configure Module page assign:
- GPIOx to
I2C SDA (6) - GPIOy to
I2C SCL (5)
After a reboot the driver will detect TSL2561 automatically and display Illuminance.

Sensor sends a tele/%topic%/SENSOR JSON reponse:
