How to configure Tasmota on ESP8266 with HD44780 and BME280?

Hello
I have assembled a circuit on ESP8266 via I2C connected is: HD44780 2X16 display and BME280 sensor. I am trying to run a circuit that will display the hour and minutes on the top line for 5 seconds on the bottom line the date. After five seconds the display will change, the top line will display the temperature from the BME sensor, the bottom line will display the temperature from the DS18B20 (which I don't have yet) and so alternate between time and temperature. I am trying to get this working by uploading a tasmot to the ESP but something is not working. When I upload the display version I have no sensor support, when I upload the sensor version there is no temeprature support. Please help how I can get this working. It can be a different firmware, writing code in arduino or something else is not an option because I don't know how to do that.

You don't have to write it. You can even compile a version online which includes display and sensors.

You only need one user_config_override.h file in which you define which elements you want to have in FW and which you do not.
