Hub time way out of sync

[gcaley]

Hi all, I was trying to work out why a driver hadnt updated for over a day, and eventually realised it wasnt the driver, but Hubitat was reporting the wrong date. I had to update the date/time from my browser to get it back working.
Is this common? Is there no way to build NTP into the hubitat code?

Thanks all.

Your HE should be updating its time via NTP. Are you blocking NTP requests? Could your internet provider be blocking NTP requests?

Good point. I'll have a look at the firewall logs. Thanks.

Your hubs firmware needs to be at least 2.1.5 then you can use this community created driver

NTP Client / Local NTP Server support

All, with the just release Hubitat version (2.1.5) there is a new function to set the Hub time via an API call. Here is a driver that allows you to specify a local NTP server to retrieve the date/time from and it will update the Hub accordingly. Right now, the driver does NOT support SNTP, only plain old NTP, however. It checks the time on boot and every X minutes (configurable). The configuration should be pretty self-explanatory but I am happy to elaborate if anyone has questions. You d…

to choose your own NTP server, by default it will try to contact a specific pool on the internet but if it cannot access the internet for a while it seems to stop trying until rebooted and if it cannot connect to the internet when the DB backup is performed each night on on reboot then it really will get out of sync like days or more. If you have a Windows machine always running on your network that NTP driver works great once you setup an NTP server service.

Ah thanks I will look to set that up. NTP is getting through my firewall ok, so this may alleviate the problem.
