I have the repeater, an IRLP computer, and the Allstar node (now on a Pi) each connected to a port on the controller. The controller currently switches on a fan for 60 seconds whenever PTT goes active. I am thinking of ditching the IRLP and the Arcom and running my repeater with the Allstar node as the controller. I?m looking for some pointers on how to control the fan with either the URI GPIO, or the USB GPIO described in the How-Tos. I guess using the URI would be simpler.</p><p class=MsoNormal>><o:p> </o:p></p><p class=MsoNormal>> Thanks,</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>You won't be sorry to dump the 210.
