Easy to setup, lots of features

Using eWelink to set this up took minutes from opening the box to fully working.

Lots of features included for timers, schedules, power limits and history. Really good value for the price.

Original purchased units have been solid

These are the second purchase I made of these devices. The first units, purchased over 2 years ago, are monitoring my washing machine and (gas) clothes dryer. With these units I am able to monitor and get alerts as to when my wash is done. I am even able to get notified if the dryer door is left open.

Great with Espurna

I buy and use these extensively after putting Espurna on them. They work fine with the included software, I just like connecting to services they don't support and using one central app.

Great product that works perfectly. Great integration within Home Assistant.

I use this to monitor the power draw of our washing machine and to send out a verbal notification to all our Alexa devices when the wash cycle is done. Works flawlessly. I highly recommend this product and will purchase more in the future.
