Eh, that ship may have sailed already…
With regard to the SD card, it has been on the roof for two winters and 1.5 summers and I am sure it wasn’t new either. Ireland so normally temperate, some wide swings in temperatures by chance in this card’s life. The packet forwarder died before, I can’t recall exactly why but I do sort of remember re-building the application using Git and Resin.io. The gateway also stopped right after a power cut/reset in one of those autumn storms. It restarted with a power cycle then but not today
