ParticipantI just received a model A, plugged it in, and nothing happened. It turns out the back plate is thick and the board moves in the case, so the power cable doesn’t always make contact with the socket. The fix was to insert the ethernet cable, and pull on that (which brings the PCB flush with the back plate) while pushing in the power connector. I’ll probably replace the plug with something a little longer at some point, but I’m fine for now. Reporting here because others might have a similar problem.
March 25, 2017 at 4:27 pm #4151ParticipantI don’t think it is related to the cable, since the box is not being moved, but it keeps rebooting. Here are some logs from the past day highlighting reboots:

March 26, 2017 at 11:39 am #4154ParticipantI have removed the back plate so that the power cable seats easily. Still rebooting, so it’s not a loose connection.
I have also replaced the USB brick with another 5V 1A model. Still rebooting.March 27, 2017 at 1:17 pm #4164uRADMonitor
KeymasterThe model A unit will reboot itself if the net is down for more than 4 minutes.
All the data received from 11000103 looks ok, and the system is functioning correctly. No need to replace power adapter or remove the end plate.
Instead, please check the Internet router, and any security settings or DHCP settings that could prevent the unit from obtaining Internet connectivity.
Alternatively, try a different Ethernet cable, or a different Internet router.
Let me know if this helps.
Thanks!
RaduMarch 27, 2017 at 7:42 pm #4199ParticipantHow is it determined if the “net is down for more than 4 minutes”?
I’m polling the unit every 20-30 seconds over the LAN and that works fine with no gaps until the reboot happens. In the logs I pasted to the forum, you can see the timestamps:
Sat Mar 25 02:32:26 EDT 2017
{“data”:{ “id”:”11000103″,”type”:”1″,”detector”:”SBM20″,”voltage”:378,”cpm”:14,”temperature”:30.25,”uptime”: 1026}}
Sat Mar 25 02:32:53 EDT 2017
{“data”:{ “id”:”11000103″,”type”:”1″,”detector”:”SBM20″,”voltage”:376,”cpm”:0,”temperature”:30.25,”uptime”: 15}}Poll at 02:32:26 . Reboot about 12 seconds later. Poll at 02:32:53.
There was no loss of LAN connectivity.
March 27, 2017 at 9:39 pm #4203KeymasterLAN is one thing, but the watchdog will do the reset if the unit cannot communicate with the server via the Internet (no HTTP 200 being received for more than 4 minutes). So it seems there is no connection to the server.
March 28, 2017 at 1:04 am #4204ParticipantOk, that makes sense. How do I disable this 4 minute timeout? or change it to something longer? My internet connection is slow, so perhaps 4 minutes is overly optimistic.
OTOH, 4 minutes is a long time, so maybe there are connectivity problems elsewhere. What is the IP that is being checked? I’d like to monitor ping and traceroute to see if there is a correlation with the reboots (because I haven’t noticed any problems using other parts of the internet during these times).
March 28, 2017 at 8:35 pm #4207KeymasterYou can see the IP when you connect to your unit’s internal webserver, directly via LAN . It is right after the “Server:” tag.
March 28, 2017 at 8:41 pm #4208ParticipantI have monitored ping times during a reboot, and they are usually between about 50mS and 200mS without any obvious drops. Simiarly, traceroute didn’t show an obvious problem.
How can I disable the 4 minute reset?
March 31, 2017 at 9:23 am #4210KeymasterIf you disable the watchdog, in case the device will fail for some unknown reason it will remain stuck until you manually reset it. I think we should find the cause of the missing server replies instead. I will investigate it on the other end and let you know what I find.
