This Shelly 1PM is a quality product. Shelly products just work how they should. I feel they are a trustworthy brand and you can actually trust the stated specifications unlike a lot of other IOT brands. I’ve fitted this in my “Fusebox” consumer unit and it fits without any modifications to the cover etc. I’ve connected this one via WiFi and it despite the metallic enclosure it is installed in, I haven’t had any issues with the connection. (WiFi signal is good tho). However I’ve also installed many of these using the Ethernet port. This is certainly my preferred method when installing for clients or installing lots of them, as you can’t beat the reliability of a wired connection. If installing wired ethernet cable in the UK you’ll need to consider: BS7671 Regulation 528.1 – Segregation of circuits Specifically, this includes the requirement that: “Where cables of different circuits are installed in the same wiring system or enclosure, the insulation of all conductors shall be suitable for the highest voltage present.” Basically standard Ethernet cable doesn’t have the required insulation specifications to be in close proximity to the mains voltage cable. You can get special Cat5 cable that does, or you could perhaps install some additional insulation over the cable. When installing them you have to consider the terminal capacity and you will likely need to use connectors in a lot of cases as the terminals will only accept a single conductor if you’re using 2.5mm or larger. The terminals have a maximum torque of 0.4Nm which is quite low. I purchased a smaller torque screwdriver to ensure I didn’t exceed this, I think a lot of the issues you see others complain about with Shelly products are caused by not following this instructions when installing. The app set up is straightforward, with multiple options to set up, including Bluetooth or scanning local network etc. The Shelly app is good, but Shelly excel at integrating with other systems such as home assistant. I’ve also used home assistant to get them to work with Apple HomeKit. You also can use these completely locally so they don’t need a cloud if you want. I’ve got this set to come on when I have cheap electricity rates to charge my partners car via the 13 amp plug she has for it. It also records energy usage and does so on time based tariffs well. I wouldn’t hesitate to buy more of these in the future

Brilliant gadget it can turn off or on anything you link it too in fuse board. little tricky to fit but after 3 minutes it’s done. i followed youtube video for tutorial as instructions are for european countries.

This is a great bit of kit. I’m partial to using DIN rails for the kit I want to permanently install because it’s better to get it in a fixed enclosure. Din rails are made for the job. I have set this up to tell me when my heating system is working or at least when the valves are sent power and when this then sends power to the pump and to the boiler. This is achievable via the switching functionality. I have used wago din rail mounted solid state relays to isolate the Shelly from the loads and connected this via Wago TopJob S din rail connectors. The switch inputs can be set to disconnected mode where they just report back if they have power fed to them or not. It’s now integrated with home assistant so when I turn on my home heating via my smart heating controls the dashboard lights up when the system is calling for heat or the hot water. The only thing is the mounting to the din rail isn’t as tight and secure as I would like to see when it’s clamped on.

Used to automated garden lights and pond. Shelly stuff just works!

But extremely good at power monitoring and Wi-Fi control

I use a lot of Shelly devices and this Shelly Pro 4PM relay module is just what I needed. I am using two of them together with Home Assistant to control 8 UFH zone actuators for the heating at home. I wanted Ethernet because wi-fi would not be rliable where they are located. My only negative comment would be that I am using them inside a small consumer unit and the depth of the modules is insufficient for the display to protrude through the slot in the way MCBs do. Functionally the modules are great!

Product is almost perfect The tech support from Shelly is far from it! Using mine installed inline in plastic box in wired custom power extension (do not like the few available extensions that are WiFi only and WAY too expensive)

More of this Shelly stuff - awesome automation. I use this one for outside of my home lighting control. Has automatic dawn/dusk control - turn all lights out in day time. Use wifi PIRs to turn the right lights on outside. Siri, Alexa etc can be used, even without IFTTT.

Very cool unit. I'm using it to control the lighting in my farm shop, the lights on the exterior of the shop, and also to trigger my electric door strike for the walk-through door and its programmed to turn the lights on if they're not already on. The coolest part is I have the fourth channel controlling a 60 amp contact closure relay to send power to my fuel barrels in my farm yard. This way no one can steal fuel All I have to do is open the app press the button and I have it programmed to shut off after 30 minutes. It works so slick! I really wish the unit had normally closed and/or dry contacts. Every output controls an additional relay because I'm either controlling 220 volts or the amperage exceeds the rating of the contacts. So the wattage function of the unit is useless in my situation. Outside of that, it works every time. I've since bought another one I'm going to wire it up to control my three-button overhead commercial door. The app to control this is very solid. If you're not patient or tech-minded you're going to struggle with this unit but stick with it and you'll get it. I'm completely hooked on these Shelly devices. I'm thinking of other ways I can use them like a timer to turn off my battery chargers for my Milwaukee tools so they don't blow up overnight. Currently wiring up exterior lights of my home on timers within the Shelly. My wife just rolls her eyes but I'm having fun! :) UPDATE: I've currently added another pro4 for more control over lights and I've added a pro 3 to control a commercial overhead door with a three-button open/ close /stop control. Each relay on the pro 3 performs the open/ close/ or stop function With an external relay for the stop circuit requiring continuous normally closed contacts. If I get around to it I'll post a picture of the wiring schematic.

Shelly Pro 2PM | WiFi worked for a month and it died, of course, the return window is closed, and I'm stuck with a faulty timer and non-working automation
