Callny G202 PLUS vs RTU5024: Which GSM Gate Opener Should You Buy?
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 only if you specifically need time-window access (open only Mon-Fri 09:00-17:00) or per-user open counters. 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.

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.
- You don't need time-window access or per-user counters.
- 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 specifically need time-window access — for example, the cleaner can only open the gate Monday to Friday between 09:00 and 17:00.
- You want per-user open counters — see how many times each authorized phone has triggered the gate.
- You're running a short-term rental and want stronger password complexity (six digits vs four).
- 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
#PWD123456#WHL002=+31612345678 Open the gate (manual relay pulse)
RTU5024
1234GOT5# Pulses relay for 5 seconds
Callny G202 PLUS
#PWD123456#GOT5000 Pulses relay for 5000ms (5s)

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 (time windows, per-user counters), but
don't choose it on price alone — you'll be trading ecosystem size for €5-10 of savings.
