ESPhome clock

Hi there,
I’m a newbie.
I want to build an accurate clock with an ESP8266 nodemcu and 4xMAX7219 dot matrix displays.
My configuration file is follows. When I installed as an ESPHome project, the clock works good for aprx. 15 minutes and then display shows 03:00 and goes on.
Is there something missing or forgetting?
Tnx.

Ok, first of all! You gotta do code formatting with that mess you copy/pasted… There are icons above your keypad or use 3x ``` above and below the code. Silly question but what was the time supposed to show after 15min? For all i know you been smoking that whacky weed and 15min ago it was 2:45.

Also, why gpio0? You really dont want to use that pin if you dont know how to use it or especially if you dont know why not to use it. Change that pin out and reflash with the updated pin#. Im surprised you got this far honestly. Didn’t see any other weird things happen? blinking led? esp going offline? anything?

You can say about formatting errors.
But you can’t decide whether a question is silly or not. I guess you think you’re a judge!
I don’t want help from you or those who think like you.

You generally should use gpio0 and gpio2 carefully, they are strapping pins and have pullups. Instead use default spi pins gpio12-15. Also you could use sntp time instead of HA.

Clearly, I was referring to my question to you.

If you go around looking to be offended, youll always find something and people like that are no fun.
