Review: Great product - 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
Review: cool gadget - 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.

### ⭐⭐⭐⭐⭐ Just the job for what I wanted to do.
*by U***D on 1 February 2025*

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.
