Hi Jean! My project is to make a new implementation of my ha-server. The server is measuring daylight, external temp. and internal temp. through the game port and use the data to control heating, light and cars on my estate. As soon as I have built the wind speed sensor that will be added to. I will start with several pcf8574 on the i2c bus (parallell port) to exchange the control functionality I have today (direct driven from the parallell port) the pcf8574's should also give me some digital inputs to fiddle with. Thanks a lot for your answer. /Andreas > Hi Andreas, > >> Must confess that I am a little confused though, and the more I read >> the more insecure I get.
