Direct comparison between the Callny G202 PLUS and the RTU5024 — the two most common GSM gate opener modules sold in 2026. We compare price, SMS protocol syntax, default password, features, ecosystem support, and ideal use cases, so you can pick the right one in five minutes.

## At a glance

For most single-gate installs, the **RTU5024** is the safer pick: cheaper, larger community, supported by every app worth using, and uses the simpler 4-digit password. Choose the **Callny G202 PLUS** if you want a longer alphanumeric password or separate admin roles, or the G203 if some users should only be able to open the gate. The two are incompatible — commands written for one will not work on the other.

The two GSM gate opener modules you're likely choosing between in 2026 are the RTU5024 (and its 4G sibling the RTU5035) and the Callny G202 PLUS (also sold as Daniu G202 and LPSECURITY G202). Together they make up roughly 85% of all GSM gate openers in residential use. Here is the honest, head-to-head comparison.

## At-a-glance comparison

| Feature | RTU5024 | Callny G202 PLUS |
| --- | --- | --- |
| Default password | `1234` (4 digits) | `1234` (4 to 12 letters and digits) |
| Command syntax | `{pwd}A001#+phone#` | `{pwd}#TEL{phone}#{userID}#` |
| Max authorized users | 999 | 999 |
| Relays | 1 (RTU5025 has 2) | 1 |
| Admin roles | No | Super admin and admin |
| Call-only users | No | G203 only |
| Community size | Large (~70% market) | Medium (~15-20%) |
| Third-party app support | Many | Few (GateOpener is one) |
| Manual quality | Poor English, lots of guides online | Multilingual quick guide, fewer online resources |
| Price (2026) | €25-45 (4G) | €20-35 |

## Choose the RTU5024 if…

- You want the cheapest reliable option for a single residential gate.
- You value being able to Google any error message and find a fix within seconds.
- A four-digit password and one level of users are enough for you.
- You may want to switch apps in the future — almost every GSM gate app on the market supports the RTU5024.
- You're replacing an existing RTU5024, RTU5015, or RTU5025 and want to keep using the same SMS commands.

## Choose the Callny G202 PLUS if…

- You want separate roles: a super admin and admins who manage users. The first number you add becomes the super admin.
- Some people, such as a cleaner, should only open the gate and never change settings. That needs the G203, which adds call-only normal users.
- You want a stronger password: up to 12 letters and digits instead of four digits.
- You're in a region where the Callny brand is easier to source locally than the King Pigeon / BLIIoT RTU5024.

## Protocol differences (the deep dive)

The two modules are *completely incompatible* at the SMS protocol level. An SMS command that works on one will be silently ignored by the other. Here's the same operation in both protocols:

### Add user +31 6 12345678 to slot 002

RTU5024

`1234A002#+31612345678#`

Callny G202 PLUS

`1234#TEL+31612345678#002#`

### Open the gate by SMS

RTU5024

`1234CC`

Switches the relay on

Callny G202 PLUS

`1234#ON#`

Switches the relay on for the set relay time

## Final verdict

For 80% of buyers, the RTU5024 (4G variant) is the right answer. It is cheaper, has a vastly larger community, and is supported by every third-party app worth installing — including GateOpener. The Callny G202 PLUS is a worthy alternative if you need its specific extras (longer passwords, admin roles), but don't choose it on price alone — you'll be trading ecosystem size for €5-10 of savings.
