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.
