I have been running this OS for a long long time. All of a sudden I could not access it, so i went and checked it and saw the 0x2D Error. I restarted it, came inside and looked the error up on the forum. Searching the forum i see it is likely an SD Card issue.
When it happened a zone was watering. I had it up in a browser and even though the zone had physically stopped, it showed the zone still running hours later.
But if it is an SD card failure, why would it boot up and be running ok after recycling the power?
I guess if i see it again, i will swap out the SD card.
