I have a BME280 connected to my V4 and it works, but I seem to recall that the expected SDA and SCL pins are different to when I used to run Meshtastic. I went down the modular DIY route for each component so changing them was easy, your mileage may vary. According to the scribbles in my notebook I think you may need to rewire as SDA is pin 17 and SCL is pin 18 with Meshcore firmware.

Try PowerSaving 16.
It supports auto select I2C addresses for BME280/680/BMP280.
