BLERelayPro: BLE Controller

BLE Play Relay Control makes it easy to connect and control BLE relay boards from your iPhone, iPad, and Apple Watch.

The app supports relay boards with 2, 4, or 8 relays and can manage multiple boards simultaneously. This allows you to control all your relays clearly from a single screen.

For each relay, you can select the desired function:

• Hold • Pulse • Toggle • Delayed off • Blink

Automatic switching based on light levels is also possible. For example, you can have a relay turn on automatically when it gets dark and set the sensitivity and delay yourself.

Customize the controls entirely to your own preferences:

• change button names • choose the shape of the buttons • adjust the text size • set the background color • set separate colors for buttons that are on or off

BLE Play Relay Control is designed for users who want to control their BLE relay boards in a clear, flexible, and local way.

If you encounter problems: check Bluetooth and the relay board’s power supply, then try reconnecting.

Supported relay boards: common BLE relay boards with 2, 4, or 8 relays.
