- Remote ON/OFF switching – Wherever you are, you can now turn on or off the connected electrical devices remotely.
- Supports four circuits - four relays in one, independent switching of four circuits within one device
- Can be fitted to the DIN rail of an electrical cabinet.
- The four circuits can be controlled separately from the mobile app
- Controlled circuits independent of the supply voltage required for the operation of the relay, even suitable for voltage-free dry contact switching.
- Pulse switching mode is also supported using the auto-off / inching function that can be set between 0.5 seconds and 1 hour
- It can also be switched to locking mode, in which the relay switches off the other 3 circuits when one circuit is switched on, so it can also be used to control rotary motors
- Physical push buttons for manual switching of the four circuits.
- Compatible with RF remote control: all four channels can be controlled separately with a fixed-code RF remote control (jump-code remote controls are certainly not compatible with it):
- the Sonoff 4CH Pro R3 (in contrast to the R2 version) can already pair several (4) remote controls per channel: e.g. it is compatible with Sonoff's 4-button remote control / Sonoff's 8-button desktop / wall remote control or SmartWise's RF wall switches, all of which are capable of remote control.
- Mobile App – Free iOS and Android mobile App: eWeLink
- Status inquiry - The mobile app shows the current status of the switch relay (on or off)
- Timing – Several timing functions are available: setting a specific time, setting repeating times, countdown / timer
- Can be shared with others - You can give access, e.g. family members for remote control
- Device groups - You can organize your devices into groups and turn several of them off or on with one click
- Smart groups - By connecting to temperature, humidity or other external sensors, you can even control the on/off automatically
- Compatibility - Connects to Amazon Alexa, Google Assistant, IFTTT and Google Nest for voice control
