What about the ledStates and btnStates for your additional LEDs and physical buttons?
Pete.
Thank you so much Pete!!! It is finally working exactly as it should. I know you spoonfed quite a bit. This is how I learn the best. I can’t just sit and read the info, make it stick and understand it. I have to make it do something practical. Here is the final code I ended up with. I’d love to hear any suggestions to make it better even though it does function perfectly.

}Celebrated a bit soon I guess. It works flawlessly when being powered by they USB port, but once I power it with a 12v power supply it gets a little crazy. Maybe just a cheap power supply sending bad power to the board? I used this same power supply with a Nano close for years for a strip of addressable LED’s without issue.
You’re still using the wrong variables in places.
Your other issue sounds like a power supply problem.

Hello, I made an automation center using an Arduino Mega and a W5500 ethernet shield, below is the code exemplifying just one physical button synchronized with Blynk’s virtual button.
Everything works perfectly until the moment that there is a failure in the internet connection, the program crashes and the physical buttons stop working…
The Ethernet.linkstatus command only works to test the cable connection, and it works very well, when you remove the internet cable the code keeps working.
Could you help me how do I make the code continue running even without internet?
Thanks

}```@Rafaorme please edit your post, using the pencil icon at the bottom, and add triple backticks at the beginning and end of your code so that it displays correctly.
Triple backticks look like this:
```
Also, I’ve deleted your duplicate post in the other topic.
Please don’t post the same question in multiple topics, it gets very messy when people star responding to both questions.
Pete.
@PeteKnight
I edited the post, and sorry for the duplicity I remembered that I had already asked about it in another post and put it there with the code.
Thanks
