Sonoff 4CH is the 4-channel standard 230V AC smart relay of the smart home product manufacturer, with embedded WiFi chip and compatibility with eWeLink app.
It uses your local WiFi network to connect to eWeLink cloud, so it is remotely controllable from eWeLink smartphone app. Also, you may create scheduled ON / OFFs, timers and set loop on / offs. eWeLink app also supports scenes, which are automation with triggers / conditions and automation actions.
This product verson does NOT have an RF 433 receiver, so it cannot be remote controlled from a near RF wireless switch or from an RF remote controller.
Sonoff 4CH (R3 version) is a popular choice for switching 4 independent gangs of 230V AC devices such as lights, sockets, and other 230V AC electronic devices. It can NOT be used for dry contact switching (for garage doors or motoric gates)!
All you need is an iOS or Android smart phone with a data plan or WiFi-based internet connection, and here you are, you can remotely turn ON / OFF the 4 gangs of the relay. You may also share app access with others. Use it wisely to save on the energy bill, automate ON/OFF at certain times, set loop ON/OFF timers for your devices.
You may also active an INTERLOCK mode to allow only usage of 1 gang at a time, so you may use it to operate 230V AC bi-directional motors.
Important: Sonoff 4CH can only be used to switch 230V AC to all 4 channels, it cannot be used to switch DC or dry contact!
