Wow! Amazingly versatile interface, works great, beautiful design.
I just discovered Shelly products and I’m impressed. It’s a beautiful small, compact, durable, and clean design. The network interface is extremely versatile, supporting many protocols. My favorite is a straight html web interface with API, which can be monitored and controlled from any computer with any software. Shelly also supports practically all the home automation stuff out there, as far as I can see. I use mine to monitor and control the AC portion of a small scale solar setup I put together myself, using my own home brew software.I have a non-Shelly product that came with a phone app for control and monitoring. There is no data logging. There is no way to use anything except their proprietary app. When I asked their customer service, they assured me that their app was unbelievably awesome and I had no need for anything else. Well. They’re wrong. Shelly is right.Shelly products have the opposite attitude. They are flexible and accommodating. Their web site has oodles of information, schematics, data sheets, and use case examples. As an engineer, I now have a crush on this company.The contacts can accommodate up to a single #12AWG wire, solid or stranded. It’s snug fit. Gently and slowly pushing in stranded wire instead of turning it works best. There are redundant contacts, so wire nuts and trying to put two wires into a contact are not necessary. DON’T try to put two wires into a contact, even if they’re small gauge. That’s what wire nuts or compression connectors are for. Don’t know what I’m talking about? Google it.Personally, I LIKE the fact that it has no mounting features, and simply hangs on the wires. AC wiring can be very tight inside a box, and if a device is bolted to the wall of the box, extra wire length has to be used, crowding the box even more, and forces are put on parts when all that wire is crammed into the box. I think most professionals would agree. The Shelly philosophy is to let the device hang where it will, like a wire nut, which is a good thing.DIYers should always read up on electrical or consult a professional before doing their own work. There are a lot of codes that seem pointless to novices but are written for good reasons. If you’re installing this device in a small box with solid wires, only strip the wires about 1/4″, so the insulation goes right up to the body with little or no bare wire showing. Bend and “dress” the wires FIRST, before attaching the device to them, and check to see that everything fits in the box with no interference. Take your time. You’ll be proud of the result, instead of a little nervous about it.

It’s small and powerful. It works great for turning any device on and off remotely.
It works well.

Cannot be permanently mounted.
I have not yet installed it, but this is a review of the physical device. It’s Nice and compact. Dealing with heavy wires in such small terminals may be awkward. There are no mounting holes nor mounting brackets, so the device must hang from its wires (unless you want to glue it to the inside of the J. box). Kind of unprofessional for a technician to leave a device just hanging. There really should be a way to mount it correctly.

Make smart plugs
They are great devices. Turns and any light switch or plug into a smart device and show how much power it pulls on top of being able to make anything smart.

Great little relay
Works great. I installed this on a fireplace Fan and couldn’t be happier.

Works great!
I connected these to all my wall switches: lights, ceiling fans, etc. No problems, work great with Google Home.

Köpt en hel del produkter med märket Shelly och jag gillar deras setup samt hur bra dom fungerar med Home Assistant och denna var inget undantag, lite långsammare i web interfacet än dimmer 2 och plug men i övrigt bra funktion.

Très bien mais l’inclusion est expliquée sur dépannage de la marque !

Der Shelly 1PM mit Leistungsmessung ist ein smarter Schalter, der Leistungen bis 16A schalten kann.Die Einrichtung mit der Shelly App klappte sofort und ist selbsterklärend. Er kann mit oder ohne Cloud, also auch rein lokal im eigenen WLAN, verwendet werden. Ein klarer Pluspunkt.Ich verwende ihn mit Home Assistant um verschiedene Verbraucher smart zu schalten. Funktioniert bisher ohne Probleme.
