The Sonoff Basic R4 is a smart switch relay is the new version of Sonoff Basic R2, the entry-level member of Sonoff's internet-controllable relay switches. As a new feature, it is also compatible with Sonoff's eWeLink-Remote remote controllers (Sonoff S-MATE / S-MATE2 modules, R5 wireless switch).
It is a relay switch module with WiFi + Bluetooth support, requiring a 230V AC power supply and can be used to switch on/off electrical appliances. Using an App running on an Internet-connected iOS (Apple) or Android mobile phone, you can remotely control the switch and set a scheduled on/off.
Of course, there is also a physical push button switch on the relay. And the remote access option via the mobile app can be shared with family members. Perfect for smart control of household electrical devices that don't need to be on all the time, but need to be switched on/off intermittently (e.g. aquarium circulator or aerator). It can be used to conveniently turn on appliances remotely before you get home, and can also be used to conveniently time off to save energy and money.
Sonoff Basic R4 does not have an external thermometer/humidity sensor input, no wired sensor can be connected.
If you also need temperature range or humidity level control, choose Sonoff TH relay series instead.
