Shelly Reviews 195

No good received, customer service doesn't answer, and when they do they lie

Very good devices, inexpensive, but reliable. They are also small and fit nicely in existent electrical systems.
I use some devices for energy monitoring with Home Assistant and it's a great combination, never had issues and downtime.
Good to see they are adding also devices with Z-Wave protocol, which has great range and keeps power consumption low.

Working with Shelly May has been amazing. She did an outstanding job with implementing North Fulton Ear, Nose & Throat Associates. Thanks

It started with one lousy star; After a firmware update, 3 Shelly Pros no longer came online and could no longer be made to work with the reset button.
Customer service was capable, they asked right questions, but did not provide a solution (after-service was clearly secondary). After lots of emails, I returned the defective pros.
Received a confirmation of receipt, but subsequently did not receive a new product and of course no further response, not even to reminders.

Nowadays I've installed a few hundred Shelly's, the delivery is getting faster and the reliability of the Shelly's is improving.
The app works stable so now Shelly get 3 stars.

Dimmers break down too quickly if an incompatible or non-dimmable light source is (accidentally) installed. There is a lot of dropout from the first series 2.5

Why Shelly? The flexibility is fantastic, the 10% failure rate after 2 years is far too high, but the savings on energy, cabling and simplification of complex circuits are many times greater.

I thought Shelly were meant to be a good company, how wrong I was.

I have a plug, that took 4 times longer to deliver than they said it would, that randomly turns itself off.

Support is hopeless, will take this up with PayPal to try to get a refund.

Steer clear of this company.
