Shelly Pro 1PM | Wi-Fi & LAN, 1-Channel Smart Relay Switch with Power Metering | Home & Facility Automation | Compatible with Alexa & Google | iOS Android App | Remote Appliances Control

I've got dozens of Shelly devices running various things around two residences, and I'll only buy the Pro PM versions any more. They've got it all, Ethernet, front-panel switches, power monitoring, etc. A bit of Python code, and a Raspberry Pi can monitor and control any number of these things. I use them in one residence to control the HVAC splits based on the solar power system battery State Of Charge, so they can run 'constantly' over the summer when I'm not there, and I can come back to a house and (especially) closets that don't smell musty when you open them up. Pricey, yes, but all the features you could ever ask for! [Don't use them for 16A loads, derate them about 50%]

Shelly's products are Excellent; they works as intended for my installation. The insallation is easy, as described in the user manual. I had used them over WIFI and works great, they works over Ethernet (LAN) and Bluetooth too.

Works great. I have started moving ALL of my smart plugs to various types of Shelly Products because they work so well.

I have numerous Shelly wifi devices and really like them. The app is great also.

The product claims "receive alerts for after work hours usage" but it is not possible with this product. I can view information but not notifications are an option. This seller was dishonest about capabilities.

Mooie degelijke techniek van Shelly, gekoppeld aan home Assistant , kan zelfstandig op eigen netwerk gebruikt worden zonder afhankelijk te zijn van een cloud provider . Aanrader, ik ga er nog meer van Shelly kopen, veel verschillende oplossingen hebben ze.

Ottimo prodotto. Nulla da dire. Funzionalità oltre le aspettative

👍🏼

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
