KR2201BY Wi-Fi Relay Switch for eWeLink, Optional Remote
Put a suitably rated wired circuit on a switching schedule instead of reaching for its switch each time. This KR2201BY single-channel relay works with eWeLink and a compatible Wi-Fi setup. It is for users arranging a properly installed smart switching circuit.
- ✅ Set a routine for switching — The app offers scheduled, countdown and loop-timer functions.
- ✅ Switch from your compatible phone — eWeLink provides the illustrated app-control interface.
- ✅ Use a handheld control in the set option — The 1set package adds the pictured remote and wall holder.
- ✅ Plan a compact installation — The small screw-terminal housing has mounting tabs for a suitable protected location.

The relay connects between a suitable supply and load using the marked input and output terminals. Its label states 90–250V AC, 50/60Hz and a 30A maximum marking. That marking does not establish suitability for every appliance, motor or starting current; the actual load and installation requirements must be checked by a qualified installer.
The eWeLink interface offers switching and timing options. Alexa and Google Home integration are stated for a compatible linked setup, with accounts, network access and any required services arranged separately. This relay is a switching device; overload protection or circuit-breaker functionality is not established.
Choose 1PCS for one relay, or 1set for one relay with the illustrated remote and holder. The remote's multiple buttons do not turn this single-channel relay into four independent channels. Remote batteries, installation wiring, controlled appliances and smart speakers are not confirmed included.
The label identifies the model, supply range and connection terminals.
Use timers and schedules for a suitable connected circuit.
An installer must check the wiring and load compatibility.
Marked input and output terminals distinguish the supply and load connections.
This is a relay switch, not a confirmed protective circuit breaker.
App control uses a compatible network and account setup.
Voice integration needs a separately configured compatible service.
