ITEAD Sonoff 4CH R2 WiFi Wireless Smart Swtich for Smart home Control four home appliances Compatible Perfectly with Amazon Alexa, Google Assistant, IFTTT, Google Nest

This has four totally independent relays and the device is separately powered. I have added it into my home heating system which has three thermostat controlled zones and hot water cylinder. I am using it in-line with the existing thermostats, which used to double up as on/off switches for each zone, and replacing the on/off timer unit. So I will now have one relay each for Boiler (including hot water), Back of house, Front of house, Upstairs. It integrates with Alexa providing voice control and if set up properly using Groups in Alexa can control the relays individually (with names such as Upstairs Heating or Boiler) or all together e.g. ("Alexa turn off all heating"). Setting the dip switches is a bit fiddly and the cable exits could be better concealed and protected but at this price I still give it 5 stars.

Connects fast, mobile app works almost instantly! Just make sure you select 2.4 on your router to set up and pair all 4 switches. As soon as it's paired successfully turn router back to 2.4 and 5ghz. Works perfectly in all modes for me. Lights, security system and garage door all work brilliantly.

Small form factor, easy installation. A great little addition to allow smart control of the lights fitted to my man cave.Getting the device to sync with my home network using the app was a bit tricky and I had to set it up in the fall back mode by connecting my phone Directly to the devices WiFi service to enter the SSID and password. Once this was done the operation has been flawless. Integration with Alexa was easy. Definitely worth the money.

I’ve used this Sonoff as parts of my smart home. I have this linked to operate my electric garage doors. It’s compatible with IFTTT and Google Home Hub and is straight forward to get up and running. Lots of videos on YouTube to help you set up. Highly recommended.

Used it for Remote siren activation when viewing an incident on security cameras. Other outputs still to use.Solid app , easy to install. No English instructions came with , but there are plenty of tutorials on you tube .

After messing about with router does not work with sky router so I got a small 2.4g hub router to make it work . Works fine with alexia also with app so I can be ĺazy and say lights off and tv off now 😎

Excellent this what I expected good value for money I buy it again

A bit fiddly to set up (toggle switches are v small and eWeLink doesn't pair straight away) but once through that, it works well!
