Re: Humidity sensor for unipi that can work with evok or owfs ?

Still looking for a 1-wire outdoor humidity/temperature sensor. I tried to order the UNICA sensor, but the web site says they are all out of stock and I don't see an option for the coated board. Any suggestions? -Thanks

Re: Digital input not detected

You got it. I had a PiFace connected to this PI previously and didn't disable the SPI bus when I removed it. As you know, it's clock is on GPIO 11 (I07). I disabled the SPI, but it still didn't work. I found a forum on line that says you have to disable it twice before the GPIO pins it uses are free...

Re: Digital input not detected

Doesn't EVOK set the GPIO pull-up resistors for the digital inputs? I am testing the UniPi analog input with a pressure sensor using the "UniPi control panel" and it works perfectly. However the control panel says Input 7 is on, but nothing is connected to any of the digital inputs and the...

Re: 24V AC Input

I thought of bridge rectifier, but I would need 8 of them. I found a gang of eight 24vac relays about the size of the ones on the UniPi, but I didn't think that was elegant and power efficient.

24V AC Input

What is the easiest and most reliable way for the UniPi to accept 24VAC digital input besides using a relay? -Thanks
