Antenna Control

[PeteKnight]

I’m assuming you’re talking about the boards that have a couple of relays and an ESP-01 on board to control them?
If so then the relays are controlled via serial commands and you would need to re-program the ESP-01 to work with Blynk. Is this what you had in mind?

Is it this type of board?..

ESP-01 and HW-655 Relay not working with Virtual Pin

I have been trying to get a ESP-01 and HW-655 relay board. I understand that the serial code needs to be sent via the esp to another chip on the relay board I have loaded the blink code that operates the relay using this serial information. Works fine I have got Blynk talking to the ESP-01 and I can turn the blue LED on and off on GPIO1 Tried using the Virtual pin to run the code to send the serial string. When I press the button on the IOS app nothing happens. The GPIO Pin will turn the LED…
