Integrate existing doorbell with NEXA WBT-912

Postby magnuslu » Sun Jul 16, 2017 4:17 pm

I want to integrate my existing traditional doorbell with the NEXA WBT-912 meaning pressing the doorbell button would also activate the WBT-912 device sending a signal to my Telldus.
I have been thinking of using a kind of relay for this purpose but since I have limited skills in electronics I have not been able to find a suitable relay. Does anyone know how to do this and what the best solution would be?
P.S I know NEXA has a doorbell device but I really want to use my existing traditional bell and button instead.

A 5 or 12V DIL relay should do the trick.
I don't know where you are located in the world, but here is a link to a Swedish re-seller:

Many thanks for your tip! I went down to Kjell & Company and bought that device and it works like a charm;) My doorbell is powered by 3 Volt instead of 5 Volt which is the specified voltage for the DIL relay but it works anyway. /Magnus
