SPI Support for BMP280

[psbankar]

Describe the problem you have/What new integration you would like

BMP280 sensor supports I2C as well as SPI but ESPHome currently supports only I2C for it. It would be great if SPI support was added for this sensor as well.

Please describe your use case for this integration and alternatives you've tried:

Same as above

Additional context

I will support this feature request! Thanks

The case is that I have a need for greater distance and the sensor supports this, in the I2C case shorter distance is required.

any progress?

Did something done for this ?

I vote for this for sensor distance. It was not clear to me it did not support it until I read this and I was attempting to research how to do exactly what is requested.

I will try to make a version of bme280 for SPI within a couple of weeks

I also look forward to this.
Another advantage for SPI over I2C - more sensors can be connected.
My understanding is Pi Pico can only support 2 x I2C BME280 (unless including a multiplexer).
But with SPI can support many more sensors.

I am also looking forward to this as I need to extend the distance to my sensors.

Is there any work in progress on this issue?

Hello! I don’t have a BMP280, I can try to write a pull request blindly, but it’s not very convenient

I happen to have one I could spare but am in the domestic US, and would not even begin to know how to get something like that to Moscow. But, out of curiosity why did you say the above if you could not do it blindly?

I have a draft pull request which adds support for BMP280 via SPI. You can test it out by adding the following to your yaml file:

external_components:
  - source:
      type: git
      url: https://github.com/ademuri/esphome
      ref: bmp280-spi
    components: [ bmp280_spi, bmp280_base ]

sensor:
  - platform: bmp280_spi
    temperature:
      name: "Board Temperature"
      oversampling: 16x
    pressure:
      name: "Board Pressure"
      oversampling: 16x
    update_interval: 5s
    cs_pin: GPIO16

spi:
  clk_pin: GPIO13
  mosi_pin: GPIO15
  miso_pin: GPIO14
  interface: hardware

If you do, feedback on whether it worked or not would be helpful.

Thanks all
