Thanks, N3tguru! I am not quite sure whether we lose the network or just lose the Zigbee, but a reboot does fix it. But we have not tried, "reboot when you lose network"; we have "reboot every day at midnight" and "clear USB buffer when it fails to change". But the latter is not foolproof: witness r...

Thanks for the quick answer. Your problems do not sound greatly different from ours, though I am not at all sure heat is the culprit. We do have a powered USB hub on our Pi (though that may not be practical for the full implementation, all 150 turbines). I am sure the Zigbees, which are not new, won...

Especially to N3tguru: how well is your Zigbee staying connected to your Raspberry Pi? We are using a Pi to collect data from wind turbines that talk via Zigbee radios (proprietary programming; we have to use the Mfger-supplied driver). The Pi rarely works flawlessly; it may lose communication with ...

It has been a long time, partly because it took us several months to get the Raspberry Pi to experiment with, and then it became necessary to try to make this work without cooperation from the wind turbine manufacturer--but, my very clever engineering student has successfully gotten our Raspberry Pi...
