Just looked at the site, wow, this will be fantastic.. The two BAE910 units
I ahve on my salt water aquarium + 1 for power monitoring have been great
since installation.
I have two projects where I will now wait, i/ weather station and ii/ an
updated aquarium controller where I needed more I/O than the original BAE910
could provide.
.
Will wait until its released before asking too many questions although I
would be interested to know if the next software release has capability to
provide some more math functions and I would still like the idea of direct
connecting a DS18B20 to an I/O pin for temperature control.

Subject: Re: [Owfs-developers] interfacing into 1wire
Hi everyone.
Indeed, I'm actively working on a new slave that allows to connect i²c
devices and more i/o.
I already have some i²c component to test connectivity like port extender,
16bit adc, 10 bit DAC, temperature sensor and eeprom. But potentially any
i²c based sensors could be accessed.
This should made easier the interfacing to your pressure sensors also.
I just got my alpha version of pcb today (see here
<http://www.brain4home.eu/index.php?option=com_content&view=article&id=38> )
but regarding the firmware development only 50% is written.
Paul already plan to support it in future release.
I will provide more info about this bae0911 soon.

I think Pascal Baerten was pondering plans for his devices that might be
relevant.

I have been putting off buying 1wire barometers and humidity sensors due to
price. I have since discovered that I can buy I2C barometers and pressure
sensors for $10 - $15.00.
I was thinking of using a simple PIC (PICAXE) to interface to the sensors
and then use a 1wire counter coupled with maybe 3 digital I/O wired between
the the pic and 1wire. I could then pulse a input line on the PIC to send
one measurement to the counter (simply as counts (0-100% or 0-1200mbar) and
then simply read the delta change in the counter module. As I will
eventually want a rain gauge I shall need the 1wire counter anyhow. Having
two channels on the counter I was thinking it maybe easy to use the second
channel for this.
Anybody else got any other simple idea's to get this type of info into
rrdtools running on my server. I could also simply provide an ascii rs232
signal direct to the port however liked the idea of using the 1wire bus.
