BLE Play Relay Control makes it easy to connect and control BLE relay boards from your 

iPhone or Apple Watch.

The app supports relay boards with 2, 4 or 8 relays and can manage multiple boards at 

the same time, up to a total of 28 relays.

This allows you to control all your relays clearly from one screen.

For each relay, you can choose the desired function:

- Hold

- Pulse

- Toggle

- Delayed off

- Blink

Automatic switching based on light level is also possible. For example, you can let a relay 

switch on when it gets dark and adjust the sensitivity and delay yourself.

Customize the controls to match your own style:

- change button names

- choose button shape

- adjust text size

- set background color

- set on/off button colors

BLE Play Relay Control is intended for users who want to control their BLE relay boards in 

a clear, flexible and local way.

depending on the board protocol.
