You can add up to 3 user defined sensors. Insert sensor's payload scheme in [*sensors.cpp*](src/sensors.cpp). Bosch BME280 / BME680 environment sensors are supported. Enable *flag lib_deps_sensors* for your board in [*platformio.ini*](src/platformio.ini) and configure BME in board's hal file before build. If you need Bosch's proprietary BSEC libraray (e.g. to get indoor air quality value from BME680) further enable *build_flags_sensors*, which comes on the price of reduced RAM and increased build size. RTC DS3231, generic serial NMEA GPS, I2C LoPy GPS are supported, and to be configured in board's hal file. See [*generic.h*](src/hal/generic.h) for all options.

Output of user sensor data can be switched by user remote control command 0x13 sent to Port 2. Output of user sensor data can be switched by user remote control command 0x13 sent to Port 2.
