Reef-Pi I2C sensor connection handling ?

[Sral]

Hi everybody,

as I have already mentioned in the main reef-Pi thread: the documentation is a bit lacking, so I'll ask here:

Can reef-Pi handle I2C or SPI sensors with their custom commands and for example multiple measurement values ?
I'm thinking, for example, about this CO2, Temperature+Humidity Sensor with calibration commands. I would like to log those values with reef-pi, is that easily possible (e.g. by declaring the write/read structure in reef-Pi), or do I have to code that myself ?

Reef-pi can handle any sensor as it has a file input driver that will import values from text file that can be used through the pH tab. If you can't edit reef-pi directly you can setup an extra script to run full time on the Pi in the background that would read the sensor and save parameter to text file so reef-pi can read it. Here's an example of how you would do such a thing.

Flow Meter Addon for reef-pi

Hi, quite a few people ask about flow meters so I thought I would make up a simple program to manage them as my skills aren't up to messing in reef-pi. I'll have to put this in the intermediate category right now as it's a little messy changing settings but it's basically set and forget so not...

Thx a lot, I was looking for a flow meter anyway !
