Allow using 3 different NTP servers and NTP over DHCP

[vortigont]

This is a really old configuration that is still used by default and allows specifying only one NTP server.
Any change this could be changed to use 3 by default?

The settings are done to save resources. We don't need more in Tasmota. If there are a good reasons to change, it will be changed. "Just" because the settings upstream are different is NO reason ;-)
NTP over DHCP will not be enabled, since it is disabled in Tasmota. Many consumer routers can't do or doing it wrong. We have been there...

[vortigont]

it will make me happy :))))
Actually resources there is only 4 bytes per server. Not sure how do you, guys, deal with only one server in Tasmota in case it becomes unreachable? Have additional code to track and switch it? It will use even more resources then 8 bytes for spare servers.
NTP over DHCP is just an option, it is disabled by default and won't interfere, you have to enable it explicitly in user code to accept opt 42.

Own code even with more NTP servers from "core", the NTP server handling is not good enough for Tasmota needs. Anyways we could waste this few bytes to make you happy ;-)

True but enabling and not using needs flash space :-(

I invested many hours to save resources as much as possible. Fighting for every byte more free. I am sure you understand that I will not sacrifice this win.

[vortigont]

Deal! :) I can live without opt 42, not a big waste.
BTW, do you backport anything to previous versions of Arduino core, i.e. 2.0.x? Or it's all long gone? :)
Would be nice to have HTTPClient lib without SSL that I pushed to upstream recently but for older core also. Still using it. Now I have to drag this patched lib into projects as a side component.
Just asking.
You've done a really good work making this core as light as possible. Impressive!

[Jason2866]

Core 2.x should possible to compile. All changes from espressif upstream branch release/v2.x are merged (soon) in Tasmota version.
BUT I do no Backport work for core 2.0.x. If you provide your HTTPClient lib without SSL as PR against Core 2.0.x here https://github.com/tasmota/arduino-esp32/tree/release/v2.x
I will merge and build a framework. Just wait until I have updated with the commits from today...

[vortigont]

That will be great! I'll come up with PR a bit later.
Thanks for all your efforts!

Btw. the last Tasmota core 2.0.17 has the TLS part stripped too in http client
You can use with

Awesome, thanks!
