Shelly 1PM Gen3 WiFi Smart Relay Switch, 1-Channel 16A

Works perfectly with Home Assistant. Quick and easy setup.

compact design with advanced features and so far reliable. Takes some electrical knowledge and a software skills (or lots of patience), but worth it.

Researched lots of pool pump time clocks and didn't want to spend that much money on them. Found these Shelly relays and love them! Recently got into smart home integration and was very happy with how easy it was to get the relay included on my home assistant instance and programming the automations was pretty easy after a few youtube videos.

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.

As with my Shelly temperature monitors, this power monitor was annoyingly difficult to get online, requiring too many tries, but once connected it has looked reliable and consistent. Also keep in mind that installing any wifi device inside a grounded steel box is not going to work well for wifi. I installed mine in a "non-metallic" electrical box and still had a PITA getting it to connect the first time. But again, once connected, works reasonably well. Load measurement agrees with my Amprobe meter. Interesting issue-- i tried it on my hard-wired water pump, which is outdoors and therefore on a GFCI circuit breaker. I had it on the load side of the breaker, and it kept tripping the GFCI. In theory this should have worked, because the Shelly device should simply appear as a tiny additional load. When i moved the Shelly to the source side of the breaker, no problems. Odd.

This little device is just great. I wrote a python web app around the Shelly device to monitor power usage of a computer system.

I am not an electrician or an engineer. I wanted to control a heated sidewalk from my phone. I simply put this in place of the manual timer, installed the app on my phone and in a few minutes it worked. Unbelievably simple. Hopefully it works for a long time. I feel certain it will.

easy to install, great instructions on YouTube. I control it with my raspberry pi using its APIs great for automation

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.

Die Firma Shelly produziert im Prinzip alles, was man zur Umrüstung bestehender Hausverkabelungen auf Smart-Home oder auch für die Erstausrüstung eines Neubaus benötigt. Man muss nur im Vorfeld genau planen, was man wie und mit welcher Funktionalität schalten möchte. In unserem Fall war der Plan, das Außenlicht, bestehend aus zwei Lampen neben der Vordertür, sowohl mit dem bestehenden Wandschalter als auch zeitgesteuert schalten zu können. Da der Schalter selbst mit einem anderen Schalter und einem Taster in einer Reihe sitzt, liegen in der entsprechenden Schalterdose nur zwei Kabel an (Phase wird geschaltet). Somit musste der Shelly in der Verteilerdose verbaut werden, da er eine dauerhafte Stromversorgung benötigt. Auf Grund der kompakten Bauweise der Shellys ist dies jedoch problemlos möglich. Wie der Shelly anzuklemmen ist, kann Schaltplänen und Youtube-Videos entnommen werden und sollte Fachleuten bekannt sein. Mit der Umrüstung kann nun unser Außenlicht sowohl mit dem Schalter bei Bedarf, per Zeitroutine oder auf Zuruf mit Alexa, durch die Shelly-App direkt oder durch einstellbare Zeiten in der App geschaltet werden. Zusätzlich kann man den Stromverbrauch im Blick behalten, was heutzutage ja immer wichtiger wird. Fazit Wer kostengünstige Smarthome-Lösungen sucht, die auch bestehende Hausschaltungen "smart" machen kann, ist bei Shelly gut aufgehoben. Die einfache Integration durch Nutzung der direkten Wlan-Anbindung ohne einen Hub, verbunden mit der hervorragend arbeitenden Shelly-App, macht die Shellys zu einer klaren Kaufempfehlung.

De momento sorprendido con las pruebas que eh realizado al equipo, muy buen performance, rapida respuesta, compacto, superfacil de configurar, muchas opciones de automatizacion e integracion.

Handige compacte WiFi schakelaar met energiemeting, met veel nieuwe mogelijkheden t.o.v. vorige generaties. Je kunt o.a. een Lora module plaatsen.

Great product , great quality, app is very stable
