I was looking for a reliable solution, here. Instead of trying to integrate Blynk as well as non-WiFi capable tasks into the same board, I decided to use two boards. One is dedicated to communicating sensor data to my phone, and one is dedicated to showing sensor data and status on the LCD as well as activating a relay if required. The non-WiFi board is monitored by the WiFi capable board, letting me know if there is a malfunction. Each board can operate independently of one another in case one does malfunction, which increases system reliability.
