Arduino Yun - not enough i2c & interrupt pins? I'm trying to build a small personal weather station. The rain sensor, and wind speed sensor use interrupts. The barometric sensor uses i2c SDA and SCL. 

Reading the Arduino Yun manual, it says there are 5 interrupt pins, but 2 of them are SCL/SDA (pins D2 and D3), and 2 of them are serial comms between Linio and the 32U4 (pins 0 and 1). 

This leaves me with 1 interrupt pin left (pin 7). 

Is there a work around to get my 2 digital sensors AND SDA SCL pins connected?

If I do use pins 0 and 1 (Linux serial), what do I risk? I will need to use the Bridge to relay information to the internet.
OR the interrupt lines together so that you only need 1 external interrupt. Then when an interrupt is triggered, poll the devices until you find the one that triggered the interrupt. If the interrupt outputs are open-drain then you can wired-OR them together, otherwise you will need something like the 74LVC32 to OR the push-pull outputs together.
