【Super Tiny Size】Its compact size allows it to be installed in various mounting boxes, including the smallest European standard.
【External Switch Control】Easily connect to the momentary switch, door exit switch, SPDT switch, latching switch, and even dry contact sensors.
【Detach Relay Mode】MINIR4 has “detach relay” mode, which means the states of external switches and relay are separated, so operating the external switch button won’t affect the relay state.
【eWeLink-Remote Control】MINIR4 is a smart switch with the gateway function of “eWeLink-Remote”. You can add “eWeLink-Remote” sub-devices, R5 and S-MATE, after pairing with MINIR4, both R5 and S-MATE can act as remote controllers to control MINIR4 locally through the eWeLink-Remote signal.
【Safe & Reliable】TÜV, CE, and FCC certifications ensure a safer and more reliable product.

Great product
Another great sonoff product easy to pair using Ewelink, well made and value for money

Small enough to fit in a lightswitch
easy to set up and work perfectly. This model does require the internet to access the smart control though, and it does need a neutral either at the switch or up at the light. I use these behind by switches so the deeper the box the better.

Very useful
Does what you need and small enough to fit into most boxes

Tight fitting into the back box but work well.
Finally wired these two into some lights at home. You’ll need deep back boxes to fit them and the cable but work well as long as they fit.

Sonoff smart switch – it is!
What an excellent little smart switch, converting my old passive hall light into a smart light, able to control using the existing switch and via my phone (via app or Home Assistant or Alexa etc..).Simple to fit if you are happy with a little bit of electrical work and have deep back box behind the switch.Was fitted and working within about 30mins and setup with some clever routines to turn on at sunset if no-one home but do nothing if someone home (Home Assistant automations). Connection to WiFi straight forward (2.4G only).Smallest smart switch on the market currently I believe, well built and looks robust. So far, can recommend.

Solid and responsive
I used one of these to make my hallway light switch smart. It fit nicely into the light switch socket along side some terminals and has been rock solid in terms of connection and responsiveness; somewhat surprising for how cheap it is. Definitely recommend but make sure to look-up some videos on YouTube on how to wire it up properly, especially if you’re using it on a two-switch wiring setup like my hallway.

One of the best things I have bought.
These are simply amazing. If you are confident enough with home electrics, these will transform your home. Combine these with WiFi bulbs and sockets and work out which option is best for you, you can effectively fully WiFi your house. Donât worry about the neutral wire – you can bypass that easily enough

Installé pour domotiser un circuit d’interrupteur “vas et vient” ça marche bien pour l’instant, juste besoin d’un module par circuit. reste à voir dans le temps..

I have smart lights in each room but don’t want to lose the wall switch function nor would it make sense to change the wall switch to a smart switch. Most smart switches do not function the way I want, which is to keep the power connected but act as a remote to the light. These are excellent modules to install behind an existing wall switch to enable smart functions and can be reprogrammed using ESPHome for exactly the behavior I want. My family doesn’t have to change their habits or learn to use some app and the lights stay connected to my Home Assistant server for smart monitoring.Installation still requires electrical knowledge and skill since the module requires both live and neutral. The screw terminals are functional but might not be strong enough to handle a full bank of solid copper wires like the romex used in North American standards. It requires some planning to make sure wires bend where they should or switching to 18 AWG stranded copper wires where possible. The wall switch connection can definitely be smaller wires since they use a low voltage.
