Sonoff minir4

Hi I’ve just installed a couple of sonoff minir4 switches into my home assistant setup to allow me to control my heating system. I bought these specifically for the detachable relay functionality. This allows me to turn off ally heating no matter if any of my switch inputs are calling for heat.

My issue is if I have detached the relay from the input switch functionality when I then disable the detach relay function it doesn’t activate the heating if the input switch is already live. This is even with the switching mode set to “follow” the switch input.

Currently the sonoff LAN integration does not give visibility of the S2 switch input status so I’ve no idea if the heating should be on or off after disabling the detach function.

Has anyone any experience of getting visibility of the S2 switch status?
