SONOFF D1 Smart Dimmer Switch

I'm a big fen of SONOFF, been using devices in the last 8 years for garage doors, liht and fans and some DUI access control.
Purchased two dimmers and two wall switches. Wall switches paired immediately, the dimmers can't be find when starting the "ADD" procedure, and one of the dimmers made popped sound when power restored, since that moment it doesn't turn on. Really disappointed with the dimmer experience...

the description of the product is correct, all the functions that are described work, I am satisfied!

It looks like a device designed for a market from a few years ago. I decided to switch devices from MOES to SONOFF but this dimmer is considerably worse than the other manufacturer's.
It doesn't have the input for external switches, this is a huge problem because it actually prevents you from being able to use it.
it's damn big and there's no support for it.
it is less accurate than that of the competition, my lamps have NEVER buzzed with the other device, with this even at 50% of the power they emit an annoying hum.

the software itead instead is better, on this there is no pargone. Better and more understandable graphics, some translation errors, however, still denote aspects to be improved

Works great! I can control the lights from anywhere i can connect to internet.

Works really well with both phones and remotes. Love the ability to turn on or off the light from anywhere

Works great, very small little module, fits inside a standard box easily.

Produit vraiment simple d'utilisation et très petit. Peux être mis dans une boite électrique existante ou même dans le plafond. Plus besoin de passer de fil jusqu'à un commutateur mural!

This is the cheapest solution to control and dim lights with mobile app, alexa and google home.

Great dimmer. I use it with LED bulbs and Home Assistant.

Item was easy to install. I added it in the overhead light, between the switch and the light.
Dimming feature is great.
The ability to control via app and set schedules is awesome
