22 Sep: The local weather server (a micro PC) has failed after over eight years of continuous operation.
The weather station is still working but can't send its data to the web server. Only the new IP camera is working as it is directly linked.
I am working on getting a replacement PC, ETA 2 weeks. In the meantime, data is being sourced from other local weather stations.
