4CH Pro R3 multiple interlock

Is there a possibility for some new firmware change to add the option for configurable INTERLOCK behavior to 4CH R3 (Pro) devices?

Instead of having an interlock between all 4 channels, to have a possibility to:

  1. Have 2 + 2 channels two dual independent interlocks
  2. Have 3 + 1 channels with one triple interlock and one independent switch
  3. Have 2+1+1 channels with one dual interlock and two independent switches

Thanks for the ideas,

@Daniel_Zhan, let’s evaluate this feature with firmware team.


I’d be very interested in this. I have two projects right now for 3+1. Both three speed single phase fans with an auxiliary fan or pump.

Yes yes yes… Definitely need this.

Any update on this?

Funtionallity is available on Tuya, they let you create INTERLOCKING GROUPS and place any of the device outputs there.

And The MHCOZY 4CH module, costs less and has all the same features, Plus the ability to have more that one interlock group. Still I wish the SONOFF did.
