Both have suddenly given me errors. For NTP it’s: Offline: Communication Error. The timeserver hostname 0.pool.ntp.org is unknown -> returning current sytem time instead.
For Yahoo Weather it’s: The Yahoo Weather API is not available for the location xxxxxx.
Any ideas please?
Just some ideas:
Are you online?
Any ports blocked by your router?
What happens, when you ping 0.pool.ntp.org?
Duh I feel dumb now. Turns out one of my network adapters had removed its static configuration, so once I set that back up, restarted OH2, back to working. And here I thought it might have been something to do with the binding instead…
Carry on peeps! 
Although I do have one potential Error: Could not connect to namespace root\OpenHardwareMonitor. Error code = 0x8004100e
This is most likely from the System Info binding, and I noticed my CPU Temperature just stays constantly on 30 degrees.
Have you updated OH recently?
What version are you using?
I am using OpenHAB 2.2.0. Have been using this since the beginning.
And your hardware?
I’m running it on a Windows 10 machine.
I don’t know windows…
Gave it up 3 years ago and not looking back.
Yes I have. I have some other things linked to the same binding and they’re working fine.
Look in event.log and verify that it actually isn’t changing.
Get a second opinion and look at the CPU temp using some opther program.
If indeed that item isn’t being refreshed as it should, put the systeminfo binding into debug or trace logging to see if you can find out anything useful.
With logs in hand, file an issue on the binding if necessary.
