Hi All,

I’m looking for smart kitchen stove knob or any good recommended smart sensor able to do retrofit and communicate to homey ? At least able to detect knob position ON/OFF please share your ideas and suggestion. Thank you 😃

Does the existing knob, switch an electric heating element or is it a Gas oven?  
In case of an Gas oven, is there somewhere room to place a micro-switch? (picture?)

Maybe a small magnet in the knob and a small zigbee door/window sensor undernees the inox plate?

Xiaomi Mijia Smart Door & Window Sensor (with round edges) are the smalest I have seen. From Banggood (not sure if they are still deliverable, otherwise the more sqare Aqara)
