You can get the part number on the Shelly website. **Q: Is this the UL Certified version?** A: A UL version is available at an additional cost. You can get the part number on the Shelly website. **Q: What is the maximum load I can run on the switch? I have 4x60w lights connected to it. The ports don't support a normal electrical wire gauge.** A: The units each have the maximum current capacity printed on them. It says :"MAX 16A" that means the maximum current is 16 amps. I have no trouble inserting #14 gauge wire in the slots. Larger size wire can carry more current than 16 Amps, so I assume it is a design feature to prevent people from wiring larger loads into the unit. **Q: Can i use this device to trigger an output based on an input? for example, if i receive 24v through a switch, i would want it to trigger an output.** A: Yes ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by J***S on 21 October 2024* Es un producto magnífico pero no funcionó para lo que necesitaba, ### ⭐⭐⭐⭐⭐ Review *by C***S on 26 June 2025* Es tal cuál lo que compras, el cable máximo creo yo que acepta es del 14 awg, para mejor 16 awg según menciona, llegó pronto y son lo que anuncian. ### ⭐⭐⭐⭐⭐ Review *by P***. on 29 August 2024* Bottom Line Up Front: These are high-quality smart relays made by a reputable company. They provide "dry contacts" (that is, they simply connect or disconnect the wires connected to the switched terminals. They do not connect the relay terminals to line voltage. The switched terminals are fully isolated from the line voltage that powers the relay.) which are useful for switching both low-voltage and line (120V or 240V AC) voltage circuits. They do not require any network access, and can be configured using the device's built-in WiFi access point or Bluetooth connection using the Shelly app or built-in webserver. You can also control the relay with a separate switch, like a regular light switch or pushbutton switch, which allows you to control loads with higher current or voltage than your switch could handle. You optionally can use the free Shelly cloud service and/or integrate it into a variety of smart home systems like Home Assistant. This model is UL listed, which means it has been tested by a third-party testing laboratory for electrical and fire safety and has passed those tests. I recommend them. Background: My house occasionally gets power outages, and also has rooftop solar and Tesla Powerwalls (to provide whole-house backup power). I wanted to ensure that my central air conditioner and electric vehicle charger would switch off when there was an outage and the batteries had been discharged to 50% or less, but neither the AC nor the charger were "smart" devices that could play nicely with my Home Assistant installation at home. Power: The relays can be powered with 120-240V AC mains power, 24-60V unregulated DC (the relay has an internal regulator), or 12V DC from a voltage-regulated power supply. Terminals: The relays have screw-type terminals that can support stranded or solid wire up to 14 AWG size (12 AWG will not fit). The manual recommends solid wire, but I've found that stranded wire with crimped ferrules work extremely well and do not loosen with time. Installation: My AC has "utility curtailment" terminals that are intended for an electric utility-provided device to signal the AC to turn off for short periods of time when the electric grid is overloaded. The AC's terminals required a dry contact relay to signal when the AC should turn off or on, which these Shelly relays have. I simply powered the Shelly using the 240V connectors in the AC unit (I added 1A fuses to the wires powering the Shelly for safety) and connected wires from the relay terminals to the AC's utility curtailment terminals. After connecting the the Shelly relay to my home's WiFi network and adding it to my Home Assistant server, I configured some Home Assistant automations to turn the relay off when the power was out and the Powerwalls were <50% full. For my car charger, I installed a Shelly relay in a similar way, except I connected the charger's "control pilot" wire to the relay terminals. When the Shelly relay is on, the charger works as expected. When the relay is off, the car and charger both detect the loss of the pilot signal and immediately stop charging and the charger opens it's high-current contactor to make the plug connector electrically safe. As far as both car and charger are concerned, the charging plug was simply disconnected. Integration with Home Assistant: Home Assistant supports these relays natively, including a bunch of useful properties like the device's internal temperature, detecting and installing firmware updates, state of the relay and the input switch terminal, and others. Integrating them with Home Assistant is a cinch. Standalone Use: When first connected, the relays operate in a "standalone" mode where each creates its own WiFi access point to which you must connect in order to configure and use them. This access point can be disabled or secured at your option. You can connect to the relay's built-in web interface or use the Shelly app to configure the device, change any communication methods (turning the access point on or off, connecting to a different WiFi network, enabling Bluetooth control, etc.). You can configure the relay with schedules, responses to certain actions, and so on. The web interface and app are both intuitive, easy to understand, and have many useful options and settings one can change. Connectivity: It is possible to use this relay with no WiFi connectivity whatsoever if that is desired. Once configured, it's possible to have the device be completely standalone, be controllable locally using Bluetooth and/or it's standalone WiFI access point, or be connected to a WiFi network with or without internet access. No cloud service is required, nor is there any dependence on any outside service. That said, Shelly does offer a free cloud service to remotely access the relays if one wishes, but it is not required. Put simply: these are great relays that do what they're advertised to do, don't require any external connectivity, and integrate well with Home Assistant. ## Frequently Bought Together - Shelly Plus 1 UL | WiFi Smart Relay Switch with Dry Contacts | Home Automation | Bluetooth Gateway | Alexa, SmartThings & Google Home Compatible | No Hub | Remote Control | Garage Door Opener (4 Pack) - Shelly Plus Add-On | Wi-Fi & Bluetooth Add-On for Shelly Plus Devices | Measure Temperature and Humidity | Home Automation | Works with Alexa & Google Home | iOS Android App |No Hub | Digital Sensor --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.id/products/747811449-shelly-plus-1-ul-wifi-smart-relay-switch-with-dry](https://www.desertcart.id/products/747811449-shelly-plus-1-ul-wifi-smart-relay-switch-with-dry) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-14*
