Hi, According to page 18 from BST-BME680-Integration-Guide-AN008-47.pdf, it should be possible no? Here pseudo code from that page:   "2.8 Simulate multiple sensors using single BSEC instance Last but not least, it is possible to simulate data collected from multiple sensors with one BSEC instance by following below integration pseudo-code: call_update_subscription() // Same sampling period and outputs for all sensors retrieve_state_file() // Get default state string call_dummy_do_step() // do_step needs to be called for proper initialization of the library. Populate input struct with time stamp equal to zero, sensor id of BSEC_INPUT_TEMPERATURE and signal equal to 25 for (i_sensor = 0; i_sensor < n_sensors; i_sensor++){ // For loop for all sensors load_state_file(i_sensor) // Load state string for the particular sensor. In case that the sensor was not used before, use default state string values from the library set_input(i_sensor, input) // Populate input struct using recorded data-point call_do_steps(input) // Call do_steps retrieve_state_file(i_sensor) // Retrieve state string for the particular sensor }" ...
