On the DieseRC EW-4CH Bluetooth remote, can I disable the 'All-on' and 'All-off' buttons to use only channels 1 through 4? Also, can I rename the channel buttons in the eWelink app to custom names like 'Gate Open'?

Based on the manual for the DieseRC EW-4CH and the standard functionality of the eWelink app, here are the answers to your questions:1. Disabling 'All-on' and 'All-off' buttons: The RM2.4G Bluetooth remote is a fixed-function hardware accessory. The manual does not provide a method to disable or unbind specific buttons like 'All-on' or 'All-off' while keeping the individual channel buttons active. These buttons are typically hardcoded to broadcast a command to all paired relays on the module.2. Renaming channel buttons in the App: Yes, you can rename the channels in the eWelink APP. To do this: Open the eWelink app and select your EW-4CH device.Tap the three dots (...) or the settings icon in the top right corner.Look for "Channel Name" or "Settings".Select the specific channel (e.g., Channel 1) and type in your custom name, such as "Slagboom open" (Gate open).If you find the 'All-on' button on the remote is causing safety issues with your gate, it is recommended to rely primarily on the App or voice control where you have more granular control over individual actions.

Қуат кірісі: The module can be powered in two ways:

Via Micro USB: DC 5V/0.5A.
Via Terminal Block: DC 7V-48V/0.5A.

Релелік қосылымдар: Each of the four relays has three terminals:

ЖОҚ (Әдетте ашық): The circuit is open when the relay is off, and closes when the relay is activated.
COM (Жалпы): The common terminal for the relay.
NC (қалыпты жабық): The circuit is closed when the relay is off, and opens when the relay is activated.

3. Құрылғыны жұптастыру

Power on the EW-4CH module.
Open the eWelink APP and tap the '+' icon to add a device.
Follow the in-app instructions to put the device into pairing mode (usually by pressing and holding the pairing button on the module until the WiFi indicator light blinks).
Connect the device to your 2.4 GHz WiFi network.

Жұмыс режимдері

The EW-4CH supports two main operating modes: Inching (Momentary) and Self-locking (Toggle).

Инч режимі: The relay activates for a set duration (e.g., 0.5 to 3600 seconds) and then automatically deactivates. This is suitable for applications like garage door openers or pulse-triggered devices.
Өздігінен құлыптау режимі: The relay toggles its state with each activation. One press turns it on, another press turns it off. This is suitable for traditional on/off control of lights or appliances.

You can configure these modes within the eWelink APP for each relay independently.
