Hi Matthew - Thanks for the pointers!
The weewx Rpi is definitely on the network, it's also my ntp service and gpsd service. The Ethernet switch to which the Davis IP data logger is connected does get a minimal handshake and the LED on the Davis IP data logger lights up and flashes intermittently. If I move the data logger to a different port (unmanaged switch) nothing changes. However, the ip data logger never responds to a ping. I suspect the data logger has entered a state that it no longer responds to queries from the network. weewx is configured to wait until network startup. To the idea that perhaps the DCHP service has a issue, I rebooted that. Did not change anything. I have no other subnets in the house, every device via the DHCP server has either a fixed IP address (like the IP data logger and the weewx RPi) or a lease. I have no unaccounted for devices. I can ping all the other devices that I know are active. The pi has wi-fi turned off. Both the weewx RPi and the IP data logger are on the same switch, within 2' of one another. The Davis console batteries are in fine shape, the console is plugged in to ac power, and I didn't lose ac power, just the dc power runs the switches and weewx RPi. (All the network gear, computers, etc., are on solar battery power.) This time I tried disconnecting the IP data logger from the network, then disconnecting ac power from the console but not removing the batteries from the console. Now the ip data logger pings. weewx starts up. This time I did not lose data! Lessons learned - don't short the 48 volt main bus %^). And, if I lose contact with the Davis IP data logger, disconnect ac power but do not remove the batteries. Next project, move the ac power supply over to the dc circuits. (It's just an odd 9 volts, so I've been lazy) Cheers - Jon On Sunday, March 30, 2025 at 8:36:08 PM UTC-7 matthew wall wrote: > also, if the pi has multiple network interfaces (e.g., wired and > wireless), be sure that weewx is using the interface that attached to the > same network that the davis is on. > > -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
