Shelly Plus 1PM WiFi Smart Relay Switch with Power Metering Home Automation Bluetooth Gateway Compatible with Alexa Google

My wife was saying she wished she could hear the machine machine buzz when the wash was done. I put this in line with the power to the washer and set it up in the app so that any time the power flow drops to zero for 5 seconds Alexa announces that the washer is done. The app has a bit of a learning curve, I set it up to notify Alexa and Alexa recognizes it as a button push, but it's a better app than most. I can't say for sure but I also get the impression that Shelly will improve it's products, including the app, unlike a lot of other iot companies. I really like the device though so maybe it's just wishful thinking. One of these days I'm going to set it up to turn all the lights on and off and play music. My wife will love that! ... actually no, no she won't. Muwahahahaha! Read more

Great for DIY automation of lights or sockets. Integrates seamlessly with Home Assistant. The build quality is good and there are plenty of YouTube tutorials explaining the wiring. Provides Power Monitoring. Only supports WiFi and Bluetooth though. Read more

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. Read more

This is an excellent device overall, great firmware and UI, easy integration with Home Assistant, able to accept sensor accessories, etc. It's extremely small and that seems to come at the cost of not having terminals large enough to accept 12AWG conductors, so it ends up needing pigtails and wire nuts which results in higher volume than if it had bigger terminals. I've been able to squeeze in 14AWG stranded, but the specified maximum for this is 16AWG which is not okay under the NEC for common 15A branch circuits. That said, I like these for building "smart" extension cords for Christmas lighting with current monitoring and programmable shutoff thresholds. Read more

Works great for my perimeter lighting Read more

Works perfectly for my 220V in-wall heater. The setup was simple, and it integrates seamlessly with Home Assistant. Power monitoring is accurate, and it's great for creating automations based on usage. Solid build, reliable performance, and very responsive. Definitely a must-have if you're looking to monitor and control high-voltage devices. Read more

What can I tell you? They work as advertised. Latency is lower than other smart switches i've used. Read more
