Best option for Iot ? blynk?

basically my projects helps grow plant and you can set various setting on the tft display

i want to connect it to the internet maybe to blynk or similar if you have any better suggestions

i have created a keyboard to enter both wifi and password which i can set as a variable for blynk

can i change values on blynk, that’ll set on the mega2560, like on and off times so change a value that was previously 4 to come on at 6 instead

if you guys have any better suggestions im open

if you guys have any good tut on blynk also id be grateful

I don't know if this

is better, but it is very well supported
