Shelly Plus 1PM | WiFi Smart Relay Switch with Power Metering | Home Automation | Bluetooth Gateway | Compatible with Alexa & Google Home | iOS Android App | No Hub | Wireless Lighting Control

Ordered to replace the same gen non-pm version for a fan automation that exists in an unattended location. I wanted to add the ability to check the current draw after turning it on or off to make sure it was actually in the command state and to monitor when it was on to detect intake blockage or bearing issues. I have written and tested the functions and they work. You have to wait a second or two to get an accurate status read, but it will work for my intended purposes. I do have to wait until I get to that location to physically install it.

We purchased this as a component to build a wifi smart switch for a 240 volt water heater, in combination with a contactor and enclosure. The switch is easy to control/schedule, although a simple interface the switch has plenty of options for most peoples needs...but if that isn't enough then you can always control it with Home Assistant, Smart Things, etc. We've been using the switch for well over a month and it has not yet once failed to start/stop the water heater at the scheduled times. This is better than any built in wifi, if the tank fails I can reuse the switch for the next one.

I used this to control a irrigation pump - I just put it in a water tight box - works great!

Good quality and reliable connection.

Great

Works great
