ShellyPM Mini Gen3 | WiFi Smart Power Meter 1 Channel 16 A | Home Automation | Bluetooth Gateway | Compatible with Alexa & Google Home | iOS Android App | No Hub Required | Smart Schedules

I really like all of the Shelly products. Admittedly, the initial setup of the first one i bought was confusing. I almost returned it but I'm very happy that i didn't. Now that I understand the how and why of setup it takes less than 2 minutes to get a new one going. They a dependable and easy to use. Love them.

This device is just what I was looking for to track consumption of a toaster oven on a dedicated circuit. It's always plugged in so I don't need the switching capability.This thing is so tiny! It easily fit behind a GFCI outlet in a standard single gang box.Paired up with the app as soon as I turned on power and Home Assistant immediately recognized it once it was connected to Wifi.I've only had it a day, but so far I'm really impressed and totally happy.

This power-monitoring-only version only saves you 30¢ versus the Shelly that does power monitoring AND switching, so the number of use-cases for this device is pretty small. The reports and information in the app is the same for both versions.That said, it does work very well. You MUST be aware of the type of outlet box you have in your wall as some homes use metal boxes for their outlets, which will greatly reduce (or block) the WiFi signal this needs to work.There's not much to look at with this, as it's meant to be small enough to install inside the wall. The most important aspect are the reports and status screens available in the app OR in your HomeAssistant dashboard. As you can see from my screenshots, you can view the current voltage and amperage in use and you can also view comparison graphs (by day, week, month or even year!This one is wired-in to the outlet for my chest-freezer. You can see that in the last 30 days it has used 32.11 kWh of electricity (or about $5.78).

Just a week installed and it's working great tracking power to my furnace!I did opt to install it into an external plastic housing since installing it in the furnace electrical box would have shielded it with two very thick steel walls and I didn't think the WiFi signal would get out.Just keep that in mind when installing; WiFi doesn't like penetrating steel walls, steel ducting, and especially chicken wire!

One of the output terminals is a little loose, but other than that it works great.

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 this case I wanted to monitor a laundry machine so I could send alerts to my phone and/or smart displays when laundry is done. I wanted a better look than a smart outlet, and I knew I didn't want control (only monitoring) so the outlet is always powered, so I got this so I could put it into the outlet box, and it worked great.

Works as described. Amazing for such a small device. Easy to setup and use

Simple to install. Fits easily into even a shallow 1-gang box with an existing receptacle. Easily associates with the phone app and Home Assistant.
