A Shelly relay can add phone control to an existing gate or garage door, but the relay is only one part of the installation. Before buying, check the controller’s command input, the available power supply and how you will reach the device over the network. If you would rather start from a working remote, 1Control SOLO offers a different route for supported models.
The useful comparison is between complete installations: a correctly fitted Shelly relay and a compatible SOLO setup. Both leave the existing motor in service. Neither fixes a faulty gate or replaces its safety devices.
Which Shelly model fits the job?
Shelly 1 Gen3 and Shelly 1 Gen4 have potential-free relay contacts. The important point is whether your controller accepts that type of command. A proprietary wall-control bus is not automatically a dry-contact input.
Do not substitute a 2PM because it has two channels: Shelly explicitly distinguishes 2PM Gen3/Gen4 from the dry-contact models for this application. Give the installer the exact module and controller references. The motor brand alone cannot establish electrical compatibility.
What the two installations include
| Check | Shelly 1 Gen3/Gen4 | 1Control SOLO |
|---|---|---|
| Command path | Relay wired to a suitable controller input | Radio signal learned from a supported working remote |
| Power | Supply compatible with the exact module | Batteries in standard SOLO |
| Nearby operation | Configured local network/control path | Phone within Bluetooth range |
| Remote operation | Suitable internet-connected setup | LINK with internet and Bluetooth reach to SOLO |
| Installation work | Wiring, configuration and testing | Guided remote learning; possible receiver authorisation |
If the remote is unsupported, SOLO KIT may provide an alternative after checking the controller. KIT requires wiring: it must not be confused with direct wireless copying.

Check power and connectivity before ordering
Ask the installer to verify voltage, AC or DC, available current, enclosure space and the controller’s command behaviour. Configure the relay for the pulse required by that controller, rather than copying an arbitrary timer value from another installation. Gate controllers can contain mains voltage; use a qualified installer for electrical work.
Shelly can be used locally on a configured Wi-Fi network: cloud access is not mandatory for every use. Opening from another location requires a suitable remote connection. Test the chosen connection where the module will sit, with the enclosure closed. A network reading beside the house does not prove coverage at the gate.
When SOLO is the simpler fit
Choose the radio route when you have a supported working remote and want nearby phone access without adding wiring to the controller. Read its full model number, check compatibility and follow the 1Control app’s learning procedure. Some receivers still require authorising the new device; wireless does not mean every installation avoids the receiver.
Test SOLO from the actual arrival point before fixing it in place. Walls and metal affect Bluetooth and radio reach. For family access, choose the version with enough included users; standard SOLO includes ten, and extra capacity may be purchased. For an overview of the other approaches, read opening a gate with your phone.
Remote access and door status are separate choices
SOLO alone operates nearby over Bluetooth. For opening while you are elsewhere, add LINK, with power and stable 2.4 GHz Wi-Fi or Ethernet, within Bluetooth reach of SOLO. LINK has no SIM. A successful command does not prove that the gate has closed.
Likewise, a relay being on or off is not the position of a garage door. Budget for a suitable status-sensing solution if that information matters. For the 1Control route, check the compatible opening sensor and second-generation LINK; see checking whether the garage door was left open.
Compare the complete purchase
Shelly is worth considering if you want a configurable relay and already have the installation skills or an installer. Include the power supply, enclosure, network improvements, labour and any position sensor in the estimate. For SOLO, include the correct version and only the accessories your use requires.
On a shared gate, agree any installation or receiver access with whoever manages it. Keep the existing remote as a fallback and test normal operation after setup. For a broader comparison beyond Shelly, use the wired-module versus wireless guide.
Frequently asked questions
Can any Shelly module control a garage door?
No. Check the exact relay output and the controller input. Shelly 1 Gen3/Gen4 have dry contacts; 2PM Gen3/Gen4 are not equivalent for this purpose.
Does Shelly always need its cloud?
No. A configured local Wi-Fi setup can operate locally. Access from elsewhere needs an appropriate remote connection.
Can SOLO copy any remote?
No. Check the exact model and variant. A working compatible remote is needed for direct learning; an unsupported model may require a wired KIT solution.
Does SOLO alone open the gate from another city?
No. The remote route requires LINK with internet and Bluetooth connectivity to SOLO.
Will either solution tell me the door is closed?
Not from the command alone. Door-position information requires a suitable sensing setup.
