Installera din RTU5024 från uppackning till första öppningen. Guiden täcker SIM-kortförberedelse, reläkoppling, lösenordsbyte, tillägg av behöriga nummer och testning.

Du har precis packat upp din RTU5024 och stirrar på ett kretskort med en antenn, en handfull skruvplintar och en manual som verkar vara översatt av en kommitté. Du är inte ensam. De flesta RTU5024-ägare tillbringar sin första timme förvirrade av kopplingen, utlåsta av PIN-koden på sitt SIM-kort, eller undrandes varför deras SMS-kommandon inte får något svar.

## Vad är RTU5024?

RTU5024 är en GSM-baserad reläkontroller som öppnar grindar, dörrar och bommar via telefonsamtal eller SMS-kommandon över mobilnätet. Enligt tillverkardokumentation från King Pigeon (BLIIoT) stöder den upp till 999 behöriga telefonnummer, drivs med 9-36V DC och är kompatibel med 2G-, 3G- och 4G LTE-nät beroende på variant. Med cirka 70% marknadsandel är RTU5024 den mest använda GSM-grindöppnaren.

Modulen lyssnar efter inkommande samtal från behöriga nummer. När den upptäcker ett stänger den sitt relä under en inställd tid, vilket aktiverar den anslutna enheten: en grindmotor, ett dörrlås, en bom eller någon annan enhet kopplad till reläplintarna.

## Steg 1: Förbered ditt SIM-kort

Before you touch the RTU5024, get your SIM card ready on a regular phone first. This step prevents the most common setup failure.

What you need: a standard-size SIM card (the large one, not micro or nano) with an active voice and SMS plan. Prepaid SIMs work fine. Data is not required.

### Remove the PIN lock

Insert the SIM into a regular phone, go to Settings, then Security, then SIM card lock, and disable the PIN. According to the [RTU5024 v1.7 user manual](http://www.rtu5024.com/download/RTU5024-V2019.pdf), the module cannot handle SIM PIN prompts. If the PIN is active, the module powers on but never registers on the network.

### Verify the SIM works

While the SIM is in your phone, send yourself an SMS and make a call. Confirm both work. Note down the SIM's phone number. You'll need it for every step that follows.

### Check network compatibility

If you bought the 2G version (most common), confirm your carrier still operates a 2G (GSM 850/900/1800/1900 MHz) network in your area. Multiple European and North American carriers have shut down their 2G networks. If your carrier no longer supports 2G, you need the 4G LTE variant instead.

## Steg 2: Sätt i SIM-kortet och anslut ström

Power off or disconnect any power source before inserting the SIM card.

1. Open the RTU5024 enclosure by removing the screws on the back panel.
2. Locate the SIM card slot on the circuit board. Push the SIM card in with the gold contacts facing down and the notched corner going in first. You should hear a click.
3. Connect a DC power supply (9-36V) to the **V+** and **GND** terminals. A 12V DC adapter is the most common choice. Make sure the polarity is correct: positive to V+, negative to GND.
4. Power on. The **POWER** LED should light up solid. The **SIGNAL** LED will blink as it searches for a network, then settle into a slow blink (roughly once every 3 seconds) when registered.

**If the SIGNAL LED keeps blinking rapidly (every second),** the module is not finding a network. This usually means the SIM PIN is still active, the SIM is not inserted correctly, or there is no compatible network coverage at your location.

## Steg 3: Koppla reläet till grinden

The RTU5024 has one relay output with three terminals: **COM** (Common), **NO** (Normally Open), and **NC** (Normally Closed). For gate openers, you almost always use COM and NO.

| Connection | Default State | When Triggered |
| --- | --- | --- |
| COM + NO | Open (disconnected) | Closes (connected) |
| COM + NC | Closed (connected) | Opens (disconnected) |

### Connecting to your gate motor

1. Find the gate motor's control board. Look for terminals labeled "push button" or "open" or "start." If you already have a wired wall button, follow those wires to the motor control board.
2. Run two wires from the gate motor's button terminals to the RTU5024's **COM** and **NO** terminals.
3. Secure the wires in the screw terminals. Give each wire a gentle tug to confirm they're held firmly.

According to the [RTU5024 datasheet](https://www.iot-solution.com/gsm-gate-opener-p00211p1.html), the relay is rated for 3A at 240VAC. You're switching the control signal, not powering the motor directly.

## Steg 4: Ändra standardlösenordet

The factory default password is `1234`. According to the RTU5024 manufacturer documentation, you should change this immediately. Anyone who knows the password can add or remove authorized users, change settings, or open your gate via SMS.

Send this SMS to your RTU5024's SIM card number:

`1234P5678`

Replace `1234` with the current password and `5678` with your new 4-digit password. The format is `{password}P{new}` with no hash delimiters. The module replies with a password changed confirmation.

The RTU5024 password is exactly 4 digits, numbers only. Pick something you'll remember but that isn't obvious.

**If you forget your password,** press and hold the RESET button on the circuit board for about 10 seconds while powered on. This restores the default password `1234` and erases all settings except stored phone numbers.

## Steg 5: Lägg till behöriga telefonnummer

Only authorized numbers can trigger the relay by calling the module. You manage the list via SMS commands.

To add your phone number to slot 001 (the primary admin slot), send:

`1234A001#+447912345678#`

Replace `1234` with your password, `001` with the slot number (001-200), and `+447912345678` with your full phone number including country code. The format is `{password}A{slot}#{phone}#`.

### Use international format

Always include your country code prefix. For UK numbers use `+44` or `0044`. For US numbers use `+1` or `001`. For Dutch numbers use `+31` or `0031`. According to community forums, omitting the country code is the second most common setup mistake after leaving the SIM PIN active.

### Slot 001 is special

This slot receives SMS confirmations when the relay activates (if enabled). Think of it as the admin slot. To add more users, repeat the command with different slot numbers:

`1234A002#+447912345679#`

For the full RTU5024 SMS command reference, see the [RTU5024 commands page](https://gate-opener.app/sv/hardware/rtu5024/commands/).

## Steg 6: Testa installationen

Call the RTU5024's SIM card number from an authorized phone number. The module should detect the call, reject it after one ring (you won't be charged), close the relay for the configured duration, and open your gate.

### If the gate doesn't open but the relay clicks

The wiring is correct but the relay close time is too short. The default may be too brief for gate motors. To set the relay time to 5 seconds, send:

`1234GOT005#`

The GOT value is a 3-digit zero-padded number in seconds: GOT005 = 5 seconds, GOT030 = 30 seconds. GOT000 = 0.5s latch pulse. GOT999 keeps the relay on until the next call (toggle mode).

### If nothing happens when you call

1. Is the SIGNAL LED blinking slowly (network connected)?
2. Did you add your number with the correct country code?
3. Are all SMS commands typed in UPPERCASE? The RTU5024 only accepts capital letters.
4. Is the access mode set to "authorized users only"? Send `1234AUT#` to re-enable authorized-only mode, or `1234EE` to check the device status.

## Steg 7: Valfria inställningar

Once the basics work, these optional settings are worth configuring.

### Check device status and signal strength

`1234EE`

The EE command returns the relay state, GSM signal strength, and firmware info. If the signal value is low, reposition the antenna or use an external antenna.

### Enable relay action notifications

`1234GON11#GateOpen#`

The GON command configures relay ON notifications. The two digits control who receives the SMS: first digit = slot 001 user (1=yes, 0=no), second digit = caller (1=yes, 0=no). The text after the second `#` is the custom message content. To disable relay ON notifications, send `1234GON##`. To disable relay OFF notifications, send `1234GOFF##`.

### Restrict to authorized users only

`1234AUT#`

This is the default, but worth confirming. The opposite (`1234ALL#`) allows any phone number to trigger the relay, which is a security risk.

## Vanliga misstag och hur du åtgärdar dem

### SIM PIN still active

The module powers on, the POWER LED lights up, but the SIGNAL LED blinks rapidly and never stabilizes. Remove the SIM, put it in a phone, disable the PIN lock, and reinsert it.

### Commands not in uppercase

Sending `1234p5678` does nothing. The RTU5024 only processes commands in capital letters. Check that your keyboard is set to uppercase and auto-correct isn't changing your input.

### Missing country code

You added your number as `07912345678` instead of `+447912345678`. The module stores numbers in international format. Without the country code, your call won't match.

### Wrong SIM card size

The RTU5024 uses a standard (full-size) SIM card. If you only have a micro or nano SIM, use an adapter. Make sure the adapter sits flush and the gold contacts align with the reader.

### Relay time too short

The default pulse may not be long enough. Increase with the GOT command (3-digit zero-padded seconds). Most gate motors work well with GOT003 (3 seconds) to GOT005 (5 seconds).

### Wiring COM to NC instead of NO

If your gate stays open and only closes when you call, you've wired to NC (Normally Closed) instead of NO (Normally Open). Swap the wire from NC to NO.

## Ställ in RTU5024 med GateOpener-appen

## Vanliga frågor

### What SIM card does the RTU5024 need?

The RTU5024 uses a standard-size SIM card (25mm x 15mm). It needs an active voice and SMS plan. Data is not required. Remove the PIN lock before inserting. If you only have a micro or nano SIM, use an adapter.

### How many phone numbers can the RTU5024 store?

According to the manufacturer specifications, the RTU5024 supports up to 999 authorized phone numbers. For SMS-based management, slots 001-200 are available directly.

### Can I use the RTU5024 with a 4G SIM card?

The original RTU5024 is a 2G device requiring a carrier with an active GSM network. If your carrier has shut down 2G, you need the RTU5024 4G variant, which supports LTE and is backward compatible with 2G/3G.

### What happens if I forget the password?

Press and hold the RESET button for about 10 seconds while powered on. This restores the default password `1234` and erases settings. Stored phone numbers are retained.

### Does the RTU5024 work during power outages?

No built-in battery. If power is lost, the module shuts down and the relay releases. For uninterrupted operation, connect a 12V UPS or battery backup to the V+ and GND terminals.

### How far can the RTU5024 be from the gate motor?

The RTU5024 connects to the gate motor via a simple two-wire cable. Standard 0.5mm or 0.75mm cable can run 50-100 meters without issue. The module needs cellular signal, not proximity to the motor.
