Unrelated to the GPIO, I seem to be having issues getting 2.0 working.
When I view the claymore dashboard, it lists the rig_ids fine and shows how many gpus/etc are installed, but it's not populating any data to the dashboard. The rig-monitor app is running, and it does seem to be communcating with the miner:
INFO: 2018/05/12 18:08:19 rig-monitor.go:40: New rig monitor job received: miner01,claymore,nanopool,,http://192.168.10.81:3333,6,180,,noplug,,900,70
INFO: 2018/05/12 18:08:19 env.go:46: New environment monitor job received: miner01,claymore,nanopool,,http://192.168.10.81:3333,6,180,,noplug,,900,70
But I see no info on the dashboard.
-r runs grm only for the specific rig. Index starts at 1 not 0
