Shelly PM Mini Gen3 WiFi Smart Power Meter 1 Channel 16 A Home Automation Bluetooth Gateway Compatible with

It is working very well. I am using it with Home Assistant but also works with the app on the phone. The first one went into the chicken house so I can see if the heat lamps were working. Sometimes they burn out. The second one watches the power for the garage fridge and the garage freezer. Through Home Assistant, I will get a notification if one unit does not pull power for 12 hours.

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). Read more

Great product, integrates with home assistant very easily. Easy to use on the shelly app if you like. I prefer to keep all my iot local and not use apps that send your info to wherever. Read more

I can’t believer how tiny this is! I’m using it to measure wattage of three outdoor flood lights, so that I can tell if one light stopped working over night. It works great for this purpose. I also use another one to watch power use by my washer, and I get a message on my phone (using this with Home Assistant) to let me know when the wash has finished. I recommend this Shelly PM mini!

This is an incredibly small power meter. You get real-time readings of intensity and voltage. It is very small. Probably smaller than the coil sensor used by other power meters. It is so small that it fits inside the electrical box, behind the outlet or switch, so it becomes "invisible". My only complaint is that the resolution of the chart, both in the cell-phone app and in the web-browser version, is very low resolution. In spite of the readings being almost in real time, the chart only shows one chart point per hour at best, even with the line chart or the full screen chart. Then, if you want to chart the last 7 days, you only get one data point per day, instead of one data point per hour. Since the hourly data is already on the server, there is not much of a reason to reduce the resolution of the charts. Apparently there is a "Premium" subscription that allows you to track the data in 1-minute intervals. No mention of this before you purchase the product. I may explore that option... Premium price is 4€/month or 36€/year. Read more

Used this power monitor to monitor the usage of my AC unit. Has worked great and had easy Home Assistant integration. Read more

It was super easy to install, much better than the normal one. I have Homeassistant and it connects perfectly with my existing system. Read more

Great product for monitoring power. Home assistant found it easily. Only challenge if using stranded wire crimp ferells on 15/20 away is a challenge. Solid core no issue Read more
