Are there plans for setting the time / NTP Server?

[Progeny42]

I've got a smart plug (HS110 UK) connected to a VLAN which has it's own DHCP and NTP server, where NTP is served via DHCP options. Apparently the plug doesn't use this, and as far as I can see, there is no way to set the time with this library.

Are there any plans to add this functionality? Or is it even possible with what TP Link provide?

I'm afraid the plugs are hardcoded to use a specific set of time servers (and I cannot recall seeing that this would be configurable, but if so, we can definitely add it to the API). I think at least at some point my plug was leveraging some *.pool.ntp.org servers (but it's been a while since I looked into that) and falling back to something else, so maybe configuring static entries to your DNS server could help?

Wrt. dhcp&ntp, to my knowledge it is rather uncommon to use the NTP server as defined in the dhcp options (I know that systemd does that, no idea about others).

Ah, I thought that would be a possibility of them being hard coded. It's not necessary for me, would just be nice to set it up.

Yeah my DHCP / NTP server setup may be a bit unconventional, but means for certain clients, it is plug and play, no client configuration needed :)

I don't actually have a DNS server setup, thought it's getting to the point where name resolution would be helpeful rather than remembering lots of IPs, and if it'll also be useful redirecting these requests in the meantime.

Thanks

I can confirm, my DHCP server returns NTP servers, the smartplugs don't pay attention to it.

I've since setup a DNS server and redirected the NTP requests to my NTP server. It works, though they seem to default to a timezone which is not mine.

There is this old PR from pyhs100 on setting the timezone, but it never got finished: GadgetReactor/pyHS100#55 . If you wish, feel free to create a PR, considering that there hasn't been much requests on that feature, I presume that most of the users of this lib are doing scheduling out of the device, e.g., using homeassistant, cron etc.
