And now everything is connected together. I had to change some values on the resistors. R6 = 10k and C4 = 10 nF gives 2.5 seconds ON time. I also changed the sensitivity from 4 s to 0.05 Seconds, I am considering changing this a bit to some greater value to increase the time some.

@Denke Probably cheaper/easier to get a complete unit, rip the electronics out and DIY the inside.

@Oitzu Ahh, sorry I missunderstood you - the other way around. I read it like you had to have the nrf attached to make it work :)

@bjornhallberg The sensors are working fine and have been installed in my home for the last couple of years. Some optimisation needs to be done to the code, that i have not done. This is more connected to understanding when the mysensors network is in "range" as i want to fallback on the manual knob if the mysensor network is inactive for some reason or if i sell the house and the controller goes with me.
