On paper seem like the ideal products… On paper seem like the ideal products for making your home smart, but there are some unacceptable deficiencies: For starters, the app is really poorly built, with very long loading times, which makes you get up and flick the button anyways. Second, the customer service is garbage, my products couldn't seem to connect to the cloud, so updates and remote control did not work for me. I emailed customer service to help with this problem, sending detailed videos and explanations of all the steps I took, but eventually they gave up on me. My advice: Don't choose Shelly just because they are a little bit cheaper compared to the rest. You will pay for it.

Shelly products are amazing through and… Shelly products are amazing through and through. I have 30+ devices. Switches, Relays bulbs work perfectly and allow for detailed settings and to me it is very intuitive. Smart home automation in an easy and economical way. What needs improvements are Motion2 detectors and Shelly Blue Door/Window. That's still a bit buggy but as I can see steady OTA firmware updates bring improvements. So despite that, I am a big Shelly fan and proud that Shelly is a European company actually!

Slow shipping and misleading information on website Order a Shelly EM module as website saying the item was in stock and then told of a shiping time of about two weeks away (after the order was placed). I messaged customer services a day after when it should have shipped to be told they are still waiting on stock. The website continues to show the product as being in stock.

I bought a single shelly relay device I bought a single shelly relay device, the shelly plus one. Initially I found it hard to determine how to wire it correctly for my application, but after getting it working it is just fantastic. With many wifi IoT devices it can be frustrating to connect the devices to your home wifi, or have other connectivity or responsiveness issues. Not so with shelly - their device is rock solid on wifi, the app is fluid and responsive, and the device just works as intended. Of all the research into different available devices to make my home smart, this company really ticks all the boxs: Affordable - compared with replacing wall switches to ugly and expensive smart switches, or worse, smart bulbs. Versatile - So many products for any niche application you can think of, and with home assistant I have ultimate control in how my smart home should work. Private - no hub or cloud servers collecting your data required. I will be outfitting my entire home with these marvelous little devices.

Terrible logistics Like many other reviews here: good product bad logistics Still waiting about 5 weeks after order Really weird messaging slash support system so not very easy to to contact Told to just wait as the courier wasn’t their problem Like others I ordered their product initially through Amazon, then made the error of going direct to Shelly after
