I have 7 GDO Blaq devices configured on my wifi. When I try and scan for devices on my Samsung phone, it sits there scanning for ever and never finds any devices. If I try to add manually, I enter the IP and port (80) click ok, it just goes back to the previous screen and doesn’t add any device or give any error message.
To add devices manually, you should not need a port number.
Tap the 3-dots menu, Add ESPHome Device, enter the IP address only, pick a unique name for each device, and select GDO blaQ from the model drop-down menu.
