Shelly 1PM Mini Gen3 WiFi Smart Switch Relay

This Shelly 1PM Mini Gen3 works great for my house lights. Tiny size fits anywhere, easy setup, accurate power monitoring, and reliable. Price is good. I’ll be buying more for my whole home automation!

These little things are awesome. They work exceptionally well and kudos on the Shelly app also. I had an atypical situation which needed an alternate wiring setup different from the instruction diagram. I submitted my diagram to them through the Shelly support site and asked if my diagram would work. They promptly replied and told me that there wouldn’t be any problem with the diagram I sent them. So technical support is an A+ too. Installed them as I needed and they work great.

Love these little relays. Works using the internet, put a backup on your router for power outages, you'll never lose internet and the relay will always work on schedule. I use it for controlling a water pump to empty my aerobic system. Never have to question whether it will work. My old analog timer was always going out. $50 to replace every 2 years. Now, these little relays are half the cost, and I hope last longer. I've had this one for about 6 months now. Working flawlessly.

I love the Shelly brand because the devices are open and can work without cloud, which is how I have it -- connected to Home Assistant. Full functionality including firmware upgrades are supported. In my case there is an indoor dimmer which controls outside lights. I wired the pm mini so the dimmer and lights were behind it and placed it into the dimmer's outlet box. I then connected it to the wifi and then Home Assistant picks it up. From there I put in an automation to turn on lights at sunset and off at 11:30pm. The power monitoring is a bonus for me and wasn't a reason why I bought it, but now I know my lights use 0.05 kWh each day, a fraction of a penny of electricity cost. The other benefit of the power monitoring is the dimmer is in the basement where it's not easily accessible, I can manipulate the dimmer and see the power usage and guesstimate how bright the lights are. I only had to set them once though. You might ask why I didn't use Shelly's awesome dimmer. Well, I did. But the LED lights are the 24 VAC kind and whatever transformer is on there caused them to blow up (as in pop and smoke) 2 Shelly dimmers at which point I just kept the old, non-digital dimmer and used this Shelly as a switch.

This is a tiny little unit for home automation. It fits neatly inside a back box and lets you control things from your phone. You can also use a variety of other tools (Alexa, Google etc) to control it by voice but I don't bother with that stuff. Installation is easy. It has three inputs - live/neutral/switch and one output. Live and neutral are obvious, and if you want to use it in conjuction with a switch the live coming from the switch goes into the switch input on this unit. Then the output from this unit is connected to the load. It will connect to 14ga wires. I have two of these, one connected to a power socket (with no switch feed) and one lurking in the box behind a light fitting powered by three-way switches. The power socket operates with a simple on/off that I set up with a timer The light is set up so that the Shelly effectively acts as a four-way switch. If I flick either of the switches the light toggles, and if I operate the Shelly I can turn the light on or off. You can also set it up so that the switch will operate normally - this means that if the switch state doesn't match the Shelly state you have to flick the switch twice to toggle the light (e.g. if the switch is off and the Shelly is on then the light is on - if you turn the switch on the light stays on and when you turn the switch off the light goes off). Where a lot of smart switches require a neutral wire, this unit can be installed behind the switch or behind the light, so if you have a switch loop you can still use it. I'm wishing I'd found these before I installed other smart switches.

Works well overall and is the smallest smart wifi relay and fits inside a electrical box, but has weak wifi in a metal box. It has convenient electrical connectors and still allows the wall switch to control the circuit AS WELL as the relay). I do wish that it worked directly with Tuya/Smart or Google Home instead of requiring the Shelly app as an additional intermediary. The Shelly app is actually quite good in its own right and quite customizable and can monitor energy usage, but It is quite complicated to get to work with SmartLife, Google Home or especially Alexa, and a bit wonky once connected (Alexa could control it, but in spite of "including" it in a group "kitchen lights", would not control it as part of the GROUP. Google Home had no such issue contolling it individually or as part of a group.

Lots of uses and ways to set them up. Amazing how well they receive WiFi signal with just a chipset antenna.

I love these Shelly relays! They’re so versatile, easy to install, easy to setup, have a great user interface within the app & seamlessly integrate into most all smart home eco systems. I have these little bad boys all over my property. Behind dumb switches to make them smart, behind 1 switch controlling 2 circuits, in line w my outdoor lighting old school timing box (to make it smart) so that when i lose power, i don’t have to manually go out there & change the time. I have them behind stadium light switches to monitor the power, make sure the lights aren’t left on for too long & to control them from anywhere. I even figured out how to use a shelly 2pm to control the motor function of pool cover! now I can automate the cover opening before my waterfalls/slides run their automatic flush cycle everyday and have it wait 10 minutes & close the cover again. All of that done automatically without me doing a darn thing! Pretty frickin cool! And they’re so inexpensive to boot! Can’t say enough good things about these bad boys. If you have a need or problem to solve that traditional circuitry, switches or plugs can’t handle, i bet some creative thinking and a Shelly can do the trick!

Simple solution to make an output smart, wiring diagram could be better described in case you don't have a switch

l'offre tarifaire était intéressante. super module pour commander à distance des éclairages extérieurs depuis le téléphone. je l'ai en plus couplé à un détecteur de mouvement.

Very small product with easy installation. What I prefer the most is that is compatible with Home Assistant.

biri 30 gün içinde bozuldu,arıza yaptı çalışmıyor.Diğerleri ne zaman arıza yapıp çalışmaz bilmiyorum.
