Automatic time update

[rroblik]

Dear all,

I've just updated both hardware (Due => ESP32) and software (2.0 => 4.1) and thanks o the help of @fredlcore all is working fine now 😸 .

I've see in config file that we setup NTP server ; so the BSB board know what time is it short time after starting up.
As I have issue with my Siemens board (date / time not retained after power loss, seems to be a hardware know issue) I ask to myself if is it possible (and also : how !) to automatically update the heatpump date/time at startup directly from the programm itself during startup (maybe in a _custom_ file) without requiring any human / external (MQTT) intervention.

Thanks a lot !

It would really help if you would at least try to make an effort to search the manual/wiki/custom_code library. Because exactly what you are looking for can be found there.

Okay sorry I didn't find it and after some research and for anyone come here : the how to is here

Thanks

[rroblik]

I used the given code but no date time update every 10 minutes. The custom command is enabled in config. Any idea ? Thanks

[fredlcore]

Sorry, from a distance and without any logs, I can't help you.

Hi, ok shame on me I didn't removed the comment before the define CUSTOM_COMMANDS 😨

I've "optimized" the things by declaring a void setHostDatetime() in BSB_LAN_custom_global.h and I use it both in BSB_LAN_custom_setup.h after 15sec delay to init date time after powerloss, for example, and in BSB_LAN_custom_global.h every hour for "security".

Again, thanks a lot for your help !

[fredlcore]

Ok, but what is the advantage to declare it in _global.h and use it in _setup.h when you have it running in the regular _custom.h every hour? Is your heater that inaccurate that after a power-loss the delay will be noticeable within an hour? Usually, the heaters have a battery-buffered clock, so a power-outage would not affect the correct date and time...

[rroblik]

Because of a know hardware issue, my heater doesn't store the clock even after a short power loss. So I don't want to wait a tick (one hour) to be on the right date time. With that I'm directly at the right date time on boot. I should have removed the "every hour time update", as once set, the date time is accurate. But cherry on cake for no cost !

[fredlcore]

Interesting, is this a general known issue of your brand model or know issue of your heater specifically? What heater model is this exactly?
To save space on your system, you could set the initial timer to exceed the counter after which the custom command is executed. This way, you'll have it executed after reboots as well as every hour :)...

[rroblik]

Yes, regarding forums it's look like an know hardware issue on Atlantic Extensa Duo (and similar with same mainboard, Siemens) even after only 5 or 6 years like mine 😞 ; also note that those models doesn't come with a dead simple 2032 battery to keep this precious information !

Bonus : I ask to myself if that behavior (automatic date / time update on boot when connection with heatpump is ok) shouldn't be "natively" integrated into your program, and activable by removing comment in front of a definelike you do for CUSTOM_COMMANDS in BSB_LAN_config.h 😊 (cherry on cake !).

Side notes:

1. I found a GetDateTime() function in main BSB_LAN file that may be usable directly (instead or recreating a similar function)
2. I don't really understand the save space you mentionned, maybe you can explain a little bit more ?

Thanks

[fredlcore]

Ok, thanks for the info. I don't integrate the NTP function because it is not available for the Arduino Due, for example. Also, for some users, it's important that BSB-LAN does not require an external internet connection as well as doing uncontrolled writes to the heating system.
Saving space was meant in the way that you don't have to set up a function and call it, but you can just set the timer variable in _setup.h to a value exceeding the comparison value so that the code will be executed right after boot and not after x seconds. But probably the memory saved is minimal, so never mind...

[rroblik]

Yes my cherry on cake was only for esp32 WITH ntp option enabled.
ok a understand thanks for clarification !
