no ACK was received

[projectdimpreza]

I tried to copy your weather station.. and i would like a button on the nextion display to show the real world state of a light.. when it is turned ON by the physical switch.. like when its ON then the button on the nextion display would change too... I manage to turn the lights ON or OFF via nextion display button.. but i had no luck in changing its actual state if i turn the light ON using the physical switch... it shows OFF on the nextion display button.. and i have a error log on esphome like this...

Sending command 'lightlamp.pic = 1' failed because no ACK was received

here is part of my esphome config..

display:

• platform: nextion id: lightdisplay update_interval: 5s lambda: |- if (id (light_status) .state) { it.send_command_printf ("lightlamp.pic = 1"); } else { it.send_command_printf ("lightlamp.pic = 0"); }

Do you know what am i missing here? thanks !
