Functionality of the real time Clock

Hi I have an RTC installed on one of my Emonpi’s it was all working ok. However I have powered it up today after a few days off with a non network connected laptop. It sees the nodes and there current temperatures but for some reason is not updating the time stamp. Once plugged into the network it starts working ok. Any Ideas? I need to use it as a remote logger as from tomorrow.



SSH into your pi.
You can set the correct time easily. First run date to verify the time is correct. Plug in Ethernet or WiFi to let the Pi sync the right time from the Internet. Once that’s done, run

[email protected]: sudo hwclock -w

to write the time, and

[email protected]:sudo hwclock -r

To check if hwclock is there:

[email protected]:timedatectl
