How to switch on light

Hi, I have an ESP8266 that mimic a real candle flame via an LED. It is working fine as it is but currently I am relying on home assistant to turn it on and off.

I would like it to turn on/off automatically without wifi presence and as a standalone device without needing home assistant to be always connected.

I have tried to modify the code but i am stuck and do not know how to continue.

I would like the ESP8266 to always turn on the candle at 5pm each day and then turn off at 8am the next day.

I am not sure how to call the ESP8266 to automatically turn on the GPIO via ESPHOME itself.

Also, will the ESP8266 remember what time it is without wifi? I am not sure about the use of the SNTP platform too.

Could someone please steer me in the right direction?

Where is my_light defined?
Isn’t that supposed to be candle?

ahh yes it is candle. I mistype there.

When i flash the code to the ESP8266, the code does not seem to run and the candle does not get turn on.

Is there any other error on my code per se? I wonder if the SNTP code is correct to be used this way?

Is it because you have a manual IP address and need to specifiy DNS ?

Also you might need reboot_timeout: 0s if you plan on using it without WIFI as it will reboot every 10 minutes without WIFI connection. Not sure time will work without WIFI though

I would add time check and time conditions. otherwise, if you turn off the electricity after executing your code, the light will not turn on

Thanks for that reboot_timeout. That might have been the issue why it wasnt working in my case but I am not entirely sure. I have now put in that line.

Thanks lordzid.

Am I understanding correctly that is running the script every 5 seconds? If so, I don’t quite understand why?

Thanks mate. If I am going to run without wifi, will the SNTP part still work?

I will give an example: the sunset has come. the light should turn on. power outage for some reason and then appeared. your condition will not be met.

Sntp will work until the power is turned off. after turning on, you need to synchronize the clock. There are separate modules for this.

Do you mean that the 5seconds time delay will happen everytime before the switching on of the GPIO?

so in my case if i wanted to switch on the GPIO at 5pm everyday, then this is telling the ESP8266 to wait 5 seconds first before switching on?

so what happens if my ESP8266 has a power failure, it won’t continue to boot because it is trying to connect to internet to synchronize the clock?

no, the device will turn on and everything will work, but no time-related automations will be performed

sorry not sure what you are referring to…are u referring to nothing will work because it cannot connect to the internet to synchronize the clock or are you referring to the 5 seconds delay?

Getting more confused.

I mean: if the Internet is disconnected, there will be no time synchronization and the conditions will not be met. when there is synchronization, every 5 seconds a check for conditions is performed and everything will work

I see! I understand now.

in my case i wanted the esp8266 to switch on automatically at 5pm and off at 8am even when there is no internet and no wifi. What should i do?

you will need This is a module And customize it. and make code.

Thanks. I will check out the GPS module - although I am not sure if my ESP8266 supports GPS.
