I’ve edited your post to add triple backticks at the start and end of your code so that the code displays correctly.

It would help if you provided some information about what this project does, what the relays control and what the app looks like.

thanks… still trying to figure out how to do that… like add a picture

This all started when we build this awesome stray cat shelter so i decided to add some remote control and monitoring capability.
I have 4 channels of relay control, a 12 amp PWM LED dimmer… and a temperature and humidity sensor.
the PWM LED dimmer will control the indoor lighting and the relays will be for outdoor light, heating pads and fan / supplemental heat

I know of several forum members who live in worse situations than the stray cats in your area!
Don’t be surprised if you find one of them curled-up in your cat house one morning (especially the ones that think that ‘cat house’ is a euphemism for something else).

Just one comment about your code. You’re using WiFiManager, but seem to be missing some of the code needed to allow it to store the credentials and Auth Code in SPIFFS. Is this something that you dabbled with then forgot to remove fully, or am I overlooking something?

it seems to be working and storing

You have SSID, Wifi Password and Auth Code hard-coded into your sketch, and once SSID and Password have been used by the ESP they will be stored anyway and it will continue to connect using these even if they are then not specified in code.
I think that if you took your device out of range of your Wi-Fi and tried to connect to a different Wi-Fi network using WiFiManager then it would probably fail. It would almost certainly not retain any credentials for the second Wi-Fi network after a reboot.

It’s only really an issue if you plan on giving one to someone else to use with their Wi-Fi and Blynk Auth Code.

im a network engineer by trade
i have several test SSID at the house and i have been switching between them.
// Blynk.begin(auth, ssid, pass); is commented out so
Blynk.begin(auth, WiFi.SSID().c_str(), WiFi.psk().c_str()); must be working yes?

Top left is a beer stain and top right is a piece of popcorn.
Obviously the stray cats aren’t very domesticated (unlike me of course :angel:) and they spill their beer and drop their popcorn when they’re watching TV in their 5 star cat shelter :open_mouth:

its a stray cat shelter and i want to monitor temp and humidity as well as have a dimmable interior LED light as well and the ability to turn on and off outdoor lighting

Is the black cat saying “Honestly Kimberley, that’s not my used hypodermic, it’s that ginger tom from down the block…”?

My cat would be swatting at and stealing all those wires sooo quick… I am often chasing her down to retrieve something I was working on :stuck_out_tongue:

one of my tuxedo cats loves to steal arduino wires and oddly places them in the food bowl after chewing on them
i have to lock her out of the lab… she does the same thing to heat shrink

That black cat is beautiful!

Are those flat brown things electric heating pads?

And I have got to ask, what is with the ball in the hoop thing?

Your trade skills show up in the orderly wiring :smiley:
