Product description
Sonoff 4CH Pro & 4CH Pro R2 are 4 gang WiFi switches. They support switching among 3 working modes: interlock/self-locking/inching mode, and both supports to set 1-16s delay in inching mode. This feature allows you to let your switch turn on for a few seconds then goes off, which works like a pulse switch. They integrate with a 433.92MHz RF receiver module, making them possible to be controlled by RF Remote. The smart switches are DIN Rail mounted. Users can remotely turn on/off the connected lights/appliances by iOS/Android App eWeLink or 433MHz RF Remote. They can create 8 enabled single/repeat/countdown timers to automatically turn on/off at the specified time. The timers can run themselves even when the network is unavailable. To let the devices be controlled by others, users can simply share the devices to other accounts and allow specified timers permissions. Users can even create some scenes or smart scenes to trigger ON/OFF the switch.

the 3 speed fan to medium. Another routine is set up to turn flame off then fan off after a 20 min pause.
The voice control seemed difficult at first as the sonoff unit has a name, then each of the 4 channels has a name so you have to append the phase of the unit name to each of the four channels. An easy work around is create Alexa routine(s) where it doesn't matter what unit name and each channel is called.

I was able able to trigger the valve to be automatically closed when water leaks are detected using eWelink smart scenes. I purchased Garosa Water Leakage Sensor 433MHz for this, along with the SONOFF RF BridgeR2 433 Smart Hub.
