Am working on a smart home project and found a smart plug, which has esp8266 …
Is it possible to update a esp82, with new code ie web server, externally, is it safe? Examples:
Yes, it should be safe if your code is working properly (but I’m not familiar with those outlets).
However, usually, after uploading your code, you’re not able to upload the original firmware (unless it is available online).
We’ve uploaded our own web server code to a sonoff smart switch and it worked well:https://randomnerdtutorials.com/reprogram-sonoff-smart-switch-with-web-server/
