It works as garage door button from galaxy smart watch LTE without even phone
I ordered this gadget to open/close my garage door without garage control just by using Galaxy LTE smart watch. It was relatively easy to connect the gadget to Dalton garage door motor. But, creation of Garage Door button and scene on my phone with Shelly Application and making it work on Galaxy Smart Watch 5 Pro LTE took some time. Most surprising that the created virtual button on the galaxy watch LTE works very far away from my home and phone. Overall: Great gadget.

Great product
Used one to add a remote control to a kitchen led strip. connecting it to Home Assistant was easy, and the product functions perfectly. recommended !

Do it all device!
What a great, do it all device! It takes a wide variety of input voltages from AC 240v down to DC 12v. It speaks a baffling number of protocols (works with zigbee, matter, wifi, Bluetooth….) It is insanely well priced for the value you get in a tiny package!It even looks like they left debug pins open, but I *like* the firmware they put on it (that *never* happens with 90% of the Internet of stuff devices I get)

Easy to connect now with Bluetooth
I like Shelly has a lot of functions most of which most won’t use . But they are cool to mess with and know you can basically control everything from how it connects to the internet or matter or zigbee, the Bluetooth function is a much improved way of connecting to the device than the old version especially when first setting up.Works with smart things too.Over all I’d say out of any Shelly I’ve tried this is the best and really only one you need.

Smart switch
Works good. Took a bit to figure out how to wire it up and get apps installed on phone but once fot it hooked up it works great.

Perfect for what I wanted
Works perfect for its purpose. Easy to setup. Smaller than I expected. Definitely a capable device.

Easy install and set up
Easier than most products like this to set up. The Matter QR code worked flawlessly. The circuit took a bit of thinking thru on my part, but once I got that figured out, the product did exactly what it was supposed to do with next to no effort. Actual user here with a fair amount of experience with automation devices, and this one is the easiest set up I’ve had so far. Will definitely buy again.

Defective. Will not connect to local network.
I’m a retired electrical engineer, so I am pretty capable with electronics. I have enjoyed the process of adding digital automation to my home. Most of my devices operate within the framework of the Samsung SmartThings network. I’ve never previously had any trouble integrating any smart device into my network.But this Shelly 1 smart relay device is terrible, in my experience. First I properly connected it to a regulated bench power supply operating at 12 volts with proper wiring. The device immediately drew high current and got warm. So, I changed to the 24 to 48 volt power option and correctly wired the same bench power supply operating at 27 volts. The device seemed to operate correctly, drawing only a small intermittent current that probably corresponded to the triggering of the WiFi, or Bluetooth, transmitter.However, I then wasted almost two hours attempting to get the device to connect with my network. Even the Shelly App could not find the device. I read through all of the Shelly 1 Knowledge Base, and attempted every recommended step, but without any success.I am returning the device to Amazon to order a different brand of smart relay.

La Gen4 ha hecho que por fin me decida a adquirir mis primeros Shelly, gracias a su compatibilidad con ZigBee. Los dispositivos funcionan a las mil maravillas y domotizar con ellos es tan sencillo como práctico. El pack sale muy a cuenta teniendo en cuenta todo lo que ofrece.

KurzfazitDer oder das Shelly hat meine Erwartungen erfüllt und ist mittlerweile täglich zur Bedienung meines Garagenrolltors im Einsatz.Lieferung & VerpackungDie Lieferung erfolgte innerhalb von einem Tag, das Produkt war sicher und wenig aufwendig, dadurch umweltfreundlich verpackt.Erster Eindruck & VerarbeitungDas Gerät wirkt hochwertig verarbeitet, ist außen eindeutig beschriftet und vor allem schön klein.Praxistest / AnwendungIch habe das Shelly vor dem Motor meines Garagenrolltors installiert. Zum Glück gibt es bei YouTube eine Menge Videos dazu und die KI ist auch sehr hilfreich.Einmal installiert ist die Bedienung sehr einfach und zuverlässig. Die Einbindung in die Shelly-App lief intuitiv und zuverlässig.Nun öffnet/ schließt mir Alexa auf Zuruf das Tor und ich habe auch aus der Ferne Zugriff!Fazit & EmpfehlungFür alle, die eine einfache und zuverlässige Lösung für die Einbindung der alten Technik in die schöne, neue Smarthome – Welt suchen, ist dieses Produkt eine klare Empfehlung. Das nächste Projekt sind meine Rolläden! 😉Wer technisch nicht so versiert ist aber besser einen Fachmann zu Installation beauftragen!
