Bosch BMP085 pressure sensor i2c on 1-wire?

[kroonen]

Hi,

I'm using a bmp085 for pressure measurement on a rpi. That wordk, but i'm limited to the rpi. I wanto to use the bosch bmp085 on fhem with 1-wire, or?? But it uses the i2c bus.

Is this possible with 1-wire, and is it simple to do?

I also bought an usb to i2c adapater on ebay, but he doesn't see it in linux

Any ideas if it should work with 1-wire?? And what do I need?

You cannot put an i2c device on the 1-W bus - totally different protocols and concepts.

You can use this sensor on I2C-bus on your raspberry with fhem. FHEM can use module (currently in beta-state) 51_I2C_BMP180.pm to do exactly what you want.

(only in German, but you will find essential informations there)

BMP180 and BMP085 use the same data, don't worry about this.
